Custom Server Controls

User control with nested GridView stops intellisense from working

richhollis — Sat, 31 Oct 2009 18:08:34 GMT

I asked this question a while ago, but I probably didn't describe it well enough, so here goes again!

I have a user control that wraps a gridview. The user control exposes the Columns property in its class definition.

Any page that uses this user control can still use the familiar GridView Columns tag in the markup (as roughly illustrated below) and the page works as expected. The wrapped gridview user control renders fine with the columns specified.

The problem with this is that intellisense stops working on the Columns element and any element inside the Columns element in the User control markup definition (e.g. BoundField, TempalteField, LinkButton etc) and the Accessibilty check throws up warnings for these user controls. It means you have to remember or lookup the attributes for each tag you use, unless you can remember.

Is there anyway to have Intellisense correctly function for nested items in this way or would you have to use a custom Control or something?

This post (http://forums.asp.net/t/1299374.aspx) looked promising - the item marked as answer I thought was a similar sort of problem.

Many thanks

Rough example code, not tested.

User Control (WrappedGridview.ascx) markup:

<div>
<asp:GridView ID="gv" runat="server" ...>
</asp:GridView>
</div>

User Control code behind (WrappedGridview.ascx.cs) code behind:

...
public DataControlFieldCollection Columns
{
     get { return gv.Columns; }
}
...

Page markup (SomePage.aspx):

<uc1:WrappedGridview>
<Columns>
<asp:BoundField ...>
<asp:TemplateField ...>
<ItemTemplate>
<asp:LinkButton ...>
...
</ItemTemplate>
</Columns>
...
</uc1:WrappedGridview>

Getting properties to show up as attributes in dom

da.3vil.genius — Sat, 21 Nov 2009 16:12:12 GMT

Okay,

So I've built a custom control with some properties and I have no problems setting them in the html but I need them to show up in the DOM.

Ex:

<uc:Example ID="myId" runat="server" myCustomAttribute="Something"></uc:Example>

The Dom needs to show

Does anyone have any ideas?

Issue Creating Custom ListView LayoutTemplate

bgibilaro — Fri, 20 Nov 2009 18:19:34 GMT

Hello,

I am working on a project where I will be displaying a set of data, however, depending on the user's settings, the columns that will be displayed will vary greatly. I am using a ListView control because of its flexible template system. I will need to define the template at run-time, since I will never know what columns need to be created and displayed until then.

So I decided to create my own LayoutTemplate and ItemTemplate classes. I am running into an issue with the LayoutTemplate (have not tried the ItemTemplate yet).

When I run my code, I get the following error:

An item placeholder must be specified on ListView ''. Specify an item placeholder by setting a control's ID property to "itemPlaceholder". The item placeholder control must also specify runat="server".

Here is the code for my LayoutTemplate class:

Public Class v_LayoutTemplate
    Implements ITemplate

    Private _strcolconfig As String

    Public Sub New(ByVal colconfig As String)
        _strcolconfig = colconfig
    End Sub

    Public Sub InstantiateIn(ByVal container As System.Web.UI.Control) Implements System.Web.UI.ITemplate.InstantiateIn
        'create a new HTML table object and set its attributes...
        Dim t As New HtmlGenericControl("table")
        t.Attributes.Add("class", "j-table")
        t.Attributes.Add("cellpadding", "3")
        t.Attributes.Add("cellspacing", "0")

        'add a table header to the table...
        Dim thead As New HtmlGenericControl("thead")

        'add the new table row objects...
        Dim tr As New HtmlGenericControl("tr")
        tr.Attributes.Add("class", "rpt_header_row")

        'create the initial columns used for icons...
        Dim th As New HtmlGenericControl("th")
        th.Attributes.Add("class", "ignore-drop")
        th.Attributes.Add("style", "border-left: solid 1px #275d86;")
        th.InnerHtml = " "
        tr.Controls.Add(th)

        th = New HtmlGenericControl("th")
        th.InnerHtml = " "
        tr.Controls.Add(th)

        'split the configuration string to get the list of columns we have to create...
        Dim arrCol As String() = _strcolconfig.Split("|")

        'create each of the content column headers...
        For Each s As String In arrCol
            th = New HtmlGenericControl("th")
            th.InnerHtml = "<divdrag"">" & s & "</div>"
            tr.Controls.Add(th)
        Next

        'add the closing column used for drag and drop purposes...
        th = New HtmlGenericControl("th")
        th.Attributes.Add("class", "ignore-drop")
        th.Attributes.Add("style", "border-right: solid 1px #275d86;")
        th.InnerHtml = " "
        tr.Controls.Add(th)

        thead.Controls.Add(tr)

        t.Controls.Add(thead)

        'create the tbody object...
        Dim tbody As New HtmlGenericControl("tbody")

        'Dim trph As New HtmlGenericControl("tr")
        'trph.Attributes.Add("runat", "server")
        'trph.Attributes.Add("id", "itemPlaceholder")

        Dim ph As New PlaceHolder()
        ph.ID = "itemPlaceholder"

        tbody.Controls.Add(ph)
        t.Controls.Add(tbody)
    End Sub
End Class

At runtime, I already have the ListView control on my webform and have simply left off the LayoutTemplate portion. (I know this is not the proper way, but I am only doing this for testing to see if I can get this to work)

Private Sub BindData()
        lvReport.LayoutTemplate = New v_LayoutTemplate("File No.|Cust No.|Opened|Entry No.|Concept|SCAC|Desc. Of Goods|ETA POE|ETA POI|ETA Dest.")

        Dim cmd As New SqlCommand("test_ReturnData", conn)
        cmd.CommandType = CommandType.StoredProcedure
        conn.Open()
        Dim rd As SqlDataReader = cmd.ExecuteReader(CommandBehavior.CloseConnection)

        With lvReport
            .DataSource = rd
            .DataBind()
        End With
        rd.Close()
    End Sub

I can't seem to find a lot of detailed on this info out on the net. Any help would be greatly appreciated.

Thanks!

Need help understanding Templated User Controls

Tasha1 — Wed, 18 Nov 2009 15:00:45 GMT

I am busy studying (exam 70-528) and I am struggling with templated user controls at the moment. In the Microsoft self paced training book they exaplian the following which I just dont understand

In the code-behind file implement a property of type ITemplate - where can I find more information on ITemplate?

Then you add a new class to the App_Data folder that contains the templates naming contianer class

SO the code will be:

public class NewClass : Control, INamingContainer

{

public NewClass(int _uID, string _uName);

{

UId = _uID;

UName = _uName;

}

public int UID

{

get{return _uID;}

set{_uID = value;}

}

private int _uID ---> WHY THIS??

The public / private property for each data element is done in both the ascx.cs and the .cs in the App_Data folder I dont understand why?

And can anyone maybe help me with some good labs that can help me practice Custom Web Controls?

Thanks

getting value on any arbitrary control

kevcpu_1 — Thu, 19 Nov 2009 19:04:38 GMT

Lets say I wanted to create my own custom validation system. Is there a way to pull the values from controls without testing whether the control is TextBox or DropDownList, further up the inheritance chain? It seems there are certain things groups of controls have in common like ".Text" property for text-based controls and ".SelectedValue" for multi-select controls. Are there any other commonalities like this and how would I go about manipulating them?

Custom Slider Control

kabir.khan.net — Wed, 18 Nov 2009 20:24:30 GMT

Hi Guys,

Is there a way to extend or customize the ajax slider control so that when it renders, it renders with different images as i provided. I want to get something like this http://www.blueshoes.org/_bsJavascript/components/slider/examples/example7.html, rather than getting generic ms slider, is it possible.

And also if i could get slider control that is already build that would be fantastic, either way i would like to know how to achieve my first question.

Thanks abunch.

Select Multiple Days in Calendar Control

aplocher — Fri, 06 Oct 2006 00:30:03 GMT

Hello, I've created a custom Calendar Control which allows you to specify various days of a month, instead of being limited to either a single day, single week, or single month. I was wondering if it's possible to somehow override the Calendar's SelectedDates.Clear(), SelectedDates.Add(), and SelectedDates.Remove() methods? SelectedDates is NOT virtual. Currently I am using specialized methods called SelectedDatesAdd(), etc, but that seems a little hoaky. I would like this to use as many of the Calendar controls built in members as possible. In fact, if the only custom public member that exists is "EnableMultiSelect", that would be ideal. This code works great, for the most part, I would just like it to use the built in members.

Here's my code:

1        public class CustomCalendar : Calendar
2        {
3            #region Private Variables
4            private const string VS_DATES = "caldates";
5

13           {
14               get { return enableMultiSelect; }
15               set { enableMultiSelect = value; }
16           }
17   
18           public void SelectedDatesClear()
19           {
20               if (enableMultiSelect)

Creating a custom image gallery control

All,

I'm considering whether I should create a custom image control for a project I'm working on, and was wondering if anyone knows of a good tutorial that could point me in the right direction. I'm looking to create something that is comparable to this:

I'm only looking to do the classic layout, so ignore all the bells and whistles on the site.

Create Event In User Control.

dpkbahuguna — Fri, 13 Nov 2009 06:45:10 GMT

Hello Friends,

I have telrik combo box , I m using this control as my Custom Control. Telrik combobox has an event named “ItemsRequested”.

I hv made an user control in which I have made a property suppose :

public string Query

{

get { return _Query; } set { _Query = value; }

}

Now I want to create an event for this control in my UserControl.ascx.cs file using delegate according to “Query “ property’s value that has been set for this control by user.

protected void Page_Load(object sender, EventArgs e)

{

if (_Query == "anything")

{

RadComboBox1.ItemsRequested += new Telerik.Web.UI.RadComboBoxItemsRequestedEventHandler(KeyPressOnCombo);

}

Please tell me that in which event I can create this event because if I do this in Page_load of the control then I am getting my Control’s property always is blank while I have set the property with a string value.

I hope I have described my query nicely.

Thanks!!

WebForm designer doesn't generate html code when I add child controls in DesignerActionMethodItem

northdevil — Mon, 16 Nov 2009 07:51:50 GMT

Hi, all.

I have a custom asp.net control and I want to give it some design time support, so I create a control designer, and override its ActionLists to return my custom DesignerActionList inherits from DesignerActionList class. I override the GetSortedActionItems property to add a DesignerActionMethodItem, which will create some child controls when user click it. the c# code just like this:

public override DesignerActionItemCollection GetSortedActionItems()
            {
                if (_actionItems == null)
                {
                    _actionItems = new DesignerActionItemCollection();
                    _actionItems.Add(new DesignerActionMethodItem(this, "AddNewCell", "add new cell", "Behavior"));
                }
                return _actionItems;
            }


            public void AddNewCell()
            {
                InvokeTransactedChange(Component, DoAddNewCell, "AddNewCell", "add new cell");
            }

            public bool DoAddNewCell(object args)
            {
                ObjectContainerCell cell = new ObjectContainerCell();

                PropertyContainer property = new PropertyContainer();
                PropertyContainerCell pc = new PropertyContainerCell();
                pc.Controls.Add(new Label());
                property.Controls.Add(pc);
                pc = new PropertyContainerCell();
                pc.Controls.Add(new InputControl());
                property.Controls.Add(pc);
                cell.Controls.Add(property);
                _control.Controls.Add(cell);
                return true;
            }

I test it in vs 2008, I saw the action list with an "add new cell" hyperlink on it. When I click this hyperlink, the design-view of vs 2008's web form designer shows me the change my code have made correctly, but when I switch to the html-view, nothing expected code was generated.

But, if I change the id of the added child control or resize it, the control's code was generated in html-view.

I have another control designer with the similar function, but it can generate code immediately when the hyperlink such as "add new cell" was clicked. But I can't find the difference between them.

I guess that I should call some method to enforce the web form designer to update the aspx file, just like the ControlDesigner.UpdateDesignTimeHtml() to enforce the designer-view to refresh the design time html.

can anybody help me?

Server Controls/User Controls best practices

xavierx — Thu, 12 Nov 2009 22:46:48 GMT

I am trying to create a library of controls to be used across my business apps. I just want it in a central location to make maintenance easier and just include the controls' references in the various projects when necessary.

I am not sure what the best approach is whether i create them all as individual server controls, compile and thus have multiple projects, one for each control...OR..

Do i create one project, include a bunch of user controls/server controls and then compile it as a single assembly and distrubute it across all the applications that way?

Or perhaps i'm totally way off in my thinking. Just thought i'd throw it out there and hopefully get some insight. Thanks for anyones time.

tdinpsp — Mon, 16 Nov 2009 06:36:06 GMT

You can't get there from here!

At least that's what I seem to be reading given what I want to do. But that doesn't seem right because the base components do what I want to do and so I would think that I should be able to do it the same way that they do. Suppose I wanted to create my own Image server control. I could add a new server control to my project and add a text property called ImageUrl. That's easy enough. But now when I override RenderContents I only have HtmlTextWriter and not the context. On the other hand if I create a HttpHandler its very easy to get the context but then I can simply drag and drop the handler onto my aspx page. Of course the regular Image control does exactly this. So my question is how does it do it, and how can I duplicate it.

Thanks in advance.

PersistenceMode.InnerDefaultProperty issue

bjones_webdev — Fri, 13 Nov 2009 20:08:22 GMT

So I'm trying to create a custom control which inherits from DropDownList.

However, I would like to essentially suppress the Items collection as the inner default property of the control and use my own. This doesn't seem to be too incredibly difficult to do, but I'm experiencing some unusual behavior for which I am unable to find a solution.

My code is essentially this:

[DefaultProperty("MyItems")]
[ParseChildren(true, "MyItems")]
public class MyCustomDropDownList : DropDownList
{
   [PersistenceMode(PersistenceMode.InnerDefaultProperty)]
   public MyItemCollection MyItems
   {
      get { ... }
   }

   [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
   public override Items
   {
      get { ... }
   }
}

public class MyItemCollection : IList<MyItem>, ICollection<MyItem>, IEnumerable<MyItem>, IStateManager
{
   ...
}

public class MyItem
{
   ...
}

The problem is that in the Source view on my page, if I attempt to add a MyCustomDropDownList control, the Intellisense for the inner property displays:

xxx:MyItem
MyItems

How do I get rid of the "MyItems" tag? I only want it to show "xxx:MyItem" as if I were using a normal list control.

"Page.ClientScript.GetWebResourceUrl" does not work

danfcosta — Fri, 29 Feb 2008 18:26:40 GMT

Hi all,

I'm trying to use an Embedded Resource Image in my custom Control, but it does not work.

Steps I done:

1) Create an Folder inside the Project (Resources);
2) Add the Image "test.gif";
3) Change the attribute "Build Action" to "Embedded Resource" on File Property Tab;
4) Add, on AssemblyInfo.vb: <Assembly: WebResource("<My Namespace>.Resources.test.gif", "image/gif", PerformSubstitution:=True)>;
5) On CreateChildControl I add:

(...)
Dim img as new Image
img.ImageUrl = Me.Page.ClientScript.GetWebResourceUrl(Me.GetType(), "<My Namespace>.Resources.test.gif")
(...)
Me.controls.add(img)

I already tried another stuffs, clean my browser cache and other suggestions. The <IMG ... /> tag appears on page source, but the image does not appear.

What I'm doing wrong?

Thanks!

Composite Validator Control ASPX vs ASCX Rendering

jpuckett — Tue, 10 Nov 2009 21:17:39 GMT

So I continue to find the DateValidation a bit unsatisfactory...

I am attempting to write a server control that handles all my Date Validation needs. I have succeeded.

The only caveat now is that when I use the control on an ASPX page, it works. When I use it inside an ASCX (to use a template) control, the <span> tag of the validator is not rendered to the HTML and I get a javascript null reference when it can't find the control by ID.

Obviously I can post all the code (might be easier for me to host a FTP of the project) relevant, but primarily, it works outside of this one tiny catch.

Note: I am not overriding CreateChildControls since I don't need to modify the output but rather all the attributes (using RegisterExpandoAttribute) of the validator to validate the Dates on the client side.

Any thoughts?

Any difference in performance in how you include control?

klandingham — Fri, 13 Nov 2009 18:38:06 GMT

Hi, I have a custom ASP.NET control that is intended to be used in various web apps in the usual way: compile into an assembly DLL, copy DLL to web app directory, add reference to web app project with tag prefix, then include tags for it in the various app pages.

However, there is one dev group in my org that has taken a different approach: they have included the source files for the control in a subfolder of their own project. I believe it then gets compiled and included in the apps assembly(s).

This seems to work but, aside from the obvious code versioning and maintenance issues, I am wondering if using the control this way (vs. having it in a separate, referenced DLL) incurs any performance penalty in terms of the time it takes to load a page, especially if a page will contain many instances of the custom control (say 20 to 30).

Thanks for any help with this question.

Persist Viewstate for Children created with ITemplate

HairyMike — Thu, 12 Nov 2009 15:29:29 GMT

Hello Coders,

I have a particularly brain frying problem today. I'd appreciate it if you can help before I test how strong the walls of the office are.

I have a custom collapsible panel control which I'm placing some custom web controls. The viewstate of my custom webcontrols is not persisting between postbacks. I think this is because inside my collapsible panel, I override CreateChildControls (to layout my controls from my ITemplate) and OnInit (to call EnsureChildControls).

The Class is defined with the following attributes:

    <DefaultProperty("Text")> _
    <ToolboxData("<{0}:CollapsingPanel runat=server></{0}:CollapsingPanel>")> _
    <Designer(GetType(CollapsingPanelDesigner))> _
    <ParseChildren(True)> _
    <PersistChildren(True, True)> _

Inside the control, I have a HeaderTemplate and a ContentTemplate which are defined as follows:

        <PersistenceMode(PersistenceMode.InnerProperty)> _
        <TemplateContainer(GetType(CollapsingPanelTemplateContainer))> _
        <TemplateInstance(TemplateInstance.Single)> _
        Public Property HeaderTemplate() As ITemplate
            Get
                Return header
            End Get
            Set(ByVal value As ITemplate)
                header = value
            End Set
        End Property

        <PersistenceMode(PersistenceMode.InnerProperty)> _
        <TemplateContainer(GetType(CollapsingPanelTemplateContainer))> _
        <TemplateInstance(TemplateInstance.Single)> _
        Public Property ContentTemplate() As ITemplate
            Get
                Return content
            End Get
            Set(ByVal value As ITemplate)
                content = value
            End Set
        End Property

Inside the override to CreateChildControls, I have this:

headerTemplateContainer = New CollapsingPanelTemplateContainer
            If HeaderTemplate IsNot Nothing Then HeaderTemplate.InstantiateIn(headerTemplateContainer)
headerPanel.Controls.Add(headerTemplateContainer)

I also have something similar for the content template. When I enable my trace for the page, all of the child controls inside the panel have 0 bytes against their viewstate. I have been looking into this all day, and am yet to find a solution. I have tried using the <ViewStateModeById> _ attribute, but still no luck. I have also checked that the controls have the same id over postbacks.

If you can help me solve this, you are a genius :)

Create reusable control that can be put on the toolbox

I am tring to create a login in control that can be generated into a dll to be used on the toolbox. However I am having issues when I try to add a reference to the dll that the login control generated. Can someone tell me what I seem to be missing. I get the following error when I link to the dll "There are no components in LoginControl.dll that can be placed on the toolbox"

Can't render the URL of a image defined in separate CSS file while embedding the CSS file as a resource

sonicdan — Tue, 10 Nov 2009 06:09:43 GMT

I have created a server control called BubbleTip.cs . I have also included two related image files, one javascript file and one css file as resource so that people don't need to do any copy & paste work when they use this control. Everything works fine by far, except the CSS background image can't display. The css file is as below:

<bubbleTips.css>

.bubbleTooltip 
{
	width: 200px;	/*fixed width for the balloon*/
	color:#000;		/*text color*/
	font: 12px sans-serif;	/*text size and style*/
	text-decoration:none;	/*other text decoration*/
	text-align:left;		/*text alignment*/
}

.bubbleTooltip span.top 
{
	padding: 30px 8px 0;
	background: url(<%=WebResource("UMControls.Images.bubble.gif")%>) no-repeat top;	
}
.bubbleTooltip span.bottom 
{
	padding:3px 8px 15px;
	color: #000;
	background: url(<%=WebResource("UMControls.Images.bubble.gif")%>) no-repeat bottom;	
}

I'm trying to dynamically refer to one of the included image resource (~\bubble\bubble.gif) in this css file, so I use <%=WebResource("UMControls.Images.bubble.gif")%> to get the URL. However, the background image can't be displayed. The Css file URL in the HTML page shows like this (in firefox):

<link href="/eStudentDev/WebResource.axd?d=dbGd6_KZGGu2Fqfa2grzPdEuPpag7Yryne9moZElvjGShyGIuTpxceJT8P0Lzhko0&amp;t=633934690050934289" rel="stylesheet" runat="server"></link>

When I follow the href link above, it jump to the CSS code that exactly as the original css file. The <%=WebResource("UMControls.Images.bubble.gif")%> part has not been replaced by the correct reference to the bubble.gif image resource.

.bubbleTooltip 
{
	width: 200px;	/*fixed width for the balloon*/
	color:#000;		/*text color*/
	font: 12px sans-serif;	/*text size and style*/
	text-decoration:none;	/*other text decoration*/
	text-align:left;		/*text alignment*/
}

.bubbleTooltip span.top 
{
	padding: 30px 8px 0;
	background: url(<%=WebResource("UMControls.Images.bubble.gif")%>) no-repeat top;	
}
.bubbleTooltip span.bottom 
{
	padding:3px 8px 15px;
	color: #000;
	background: url(<%=WebResource("UMControls.Images.bubble.gif")%>) no-repeat bottom;	
}

My question is how I can make the image URL in the separate CSS resource be converted into the correct resource reference? Or is this possible or not?

Thanks!

Custom control : getting Rowcount 0 on button event of the control.

imran_khan — Fri, 06 Nov 2009 06:38:13 GMT

I am working on custom control. I am creating databound control. I have one property name RowDataSource that
accept DataRowCollection as data source and I bind control on OnDataBinding event. I have another property
name RowItem.
My code looks like this.

public DataRowCollection RowDataSource
{
	get
    {
		if (ViewState["rowDataSource"] == null)
		{
	        ViewState["rowDataSource"] = null;
		}
        return (DataRowCollection)ViewState["rowDataSource"];
    }
	set
    {
		if (value == null)
		{
			throw new ArgumentException("unvalid data source.", this.ID);
		}
		ViewState["rowDataSource"] = value;
	}
}
public RowCollections ExelRows
{
   get
   {
   // rCollection is object of RowCollections class
	if (rCollection == null)
        {
           rCollection = new RowCollections();
        }
        return rCollection;

   }
}

//OnDataBinding event code
protected override void OnDataBinding(EventArgs e)
{
	base.OnDataBinding(e);
	if (RowDataSource != null)
	{
		foreach (DataRow dr in RowDataSource)
		{
		    //RowItem is my class
			RowItem item = new RowItem();
			item.Text = dr[rTitle].ToString();
			this.ExelRows.Add(item);
		}
	}
}
   
//CreateChildControls method to render control		 
protected override void CreateChildControls()
{
	if (ExelRows.Count > 0)
	{
		//here i am rendering table structure to add exelrows and create control.
	}
}

Now, I am binding this control with DataRowCollection and It works file. I have one button in this control and
I am raising bubble event when button is clicked.

My problem is that when I click on button then CreateChildControls method is called first before OnDataBinding event.
so I am getting ExelRows.Count = 0.

so what I have to do to getting all rows on every bubble event of control.

winned — Thu, 12 Nov 2009 04:29:31 GMT

I have a BaseUsercontrol

say suppose Base User Control has Load and create buttons

Usercontrol1:BaseUsercontrol

{

}

UserControl2:BaseUsercontrol

{

}

On my webpage , I have added this BaseUserControl.

UserControl1 and UserControl2 are loaded dynamically

How to handle the Load_Click and Create_Click of BaseuserControl in respective UserControls. I may also need to be able to use these events in the in the individual user controls as well as web page.

Thanks

a custom control that does not render

kevcpu_1 — Thu, 05 Nov 2009 01:23:37 GMT

is it possible to create a control that contains child controls without rendering it. So, when I add it to the page it should look like....

<test:parentcontrol id="parent1" runat="server" property1="value1" ... propertyn="valuen">

<test:childcontrol id="child1" runat="server" property1="value1" ... propertyn="valuen"/>

<test:childcontrol id="child3" runat="server" property1="value1" ... propertyn="valuen"/>

</test:parentcontrol>

and have the render empty, because it does not equate to anything on the html side. Further, can I cycle through the child control of the parent using the following methodology within the code_behind file:

foreach (Control control in parent1.Controls){

.......

}

would this be possible if I am not technically rendering anything? Also, would I have to do anything special with creating the parent and child controls?

Help with template control

sroughley — Mon, 09 Nov 2009 14:24:13 GMT

Hi all,

I am building a control that will report data errors or successful data actions back to the user and have run into a problem and am stuck. Bascially, the control uses a layout template to allow the UI developer to specify how to display errors:

        <cc1:DataReporter ID="DataErrorReporter1" runat="server">
            <ErrorLayoutTemplate>
                <h2><asp:Literal ID="ErrorHeaderText" runat="server" /></h2>
                <ol>
                    <asp:PlaceHolder ID="errorItemPlaceHolder" runat="server" />
                </ol>
                <h2><asp:Literal ID="ErrorActionText" runat="server" /></h2>
            </ErrorLayoutTemplate>
            <ErrorItemTemplate>
                <li><asp:Literal ID="ErrorMessage" runat="server" /></li>
            </ErrorItemTemplate>
        </cc1:DataReporter>

The problem is that i cannot get the control to output the ErrorItemTemplate contents in the errorItemPlaceholder and that i am also seeing some spurious span tags being output:

        <span id="DataErrorReporter1"><span>
                <h2></h2>
                <ol>
                    
                </ol>
                <h2></h2>
            <span>
                <li></li>
            </span><span>
                <li></li>
            </span><span>
                <li></li>
            </span><span>
                <li></li>
            </span><span>
                <li></li>
            </span><span>
                <li></li>
            </span><span>
                <li></li>
            </span><span>
                <li></li>
            </span><span>
                <li></li>
            </span><span>
                <li></li>
            </span><span>
                <li></li>
            </span></span></span>

The code for the control is as follows:

    Friend Class DataReporterLayoutContainer
        Inherits WebControl
        Implements INamingContainer

    End Class

Can any of you guys point out where I'm going wrong? The action takes place in the CreateItems method. It basically instantiates the ErrorLayoutTemplate, gets the errorItemPlaceholder and attempts to add the errors to this. Any help you have to offer would be greatly appreciated!

Regards,

I am looking at the asp:calendar control, and I'm wondering how hard it would be to develop a similar control for picking time slots (30mins) of a 24 hour day?

Has anyone attempted this?

I would be interested in any discussion on this.

Thanks in advance.
