AsyncPostbackTrigger, but no AsycPostback

mPhilipp — Tue, 24 Nov 2009 13:59:15 GMT

Hi,

I have a problem with ajax. I worte a little testsite (->.aspx) with ScriptManager, UpdatePanel,.. And after it worked how i wanted it, i took the code and made a control out of it(->.ascx).

Now no AsyncPostback is done, just normal Postbacks.

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="TelephoneBox.ascx.cs" Inherits="de.badi.app.Bps3.modules.Swyx.controls.TelephoneBox" %>

Hide/Show panel on RadioButtonList inside ListView

.net-newbie — Tue, 24 Nov 2009 18:37:46 GMT

I'm trying to hide/show a panel according to user's selection(from a RadioButtonList) but I keep getting the error "Object reference not set to an instance of an object." Apparently, it doesn't seem to find the panel control. I checked the view source and the panel ID gets replace by something like this "..._ctrlX_Panel1" (x being number of row returned). Is there a way to find out the panel id within the same selected row?

This is what I have in my aspx file:

<asp:RadioButtonList ID="rbl1" runat="server" DataMember="Yes" DataTextField="recommendation"
                                                DataValueField="Yes" SelectedValue='<%#Eval("recommendation")%>' OnSelectedIndexChanged="showCommentsBox"
                                                AutoPostBack="true">
                                                <asp:ListItem Text="Yes" Value="1"></asp:ListItem>
                                                <asp:ListItem Text="No" Value="0"></asp:ListItem>

                                            </asp:RadioButtonList>

<asp:Panel ID="Panel1" runat="server" Visible="false">

//some stuff here

</asp:Panel>

aspx.cs file

protected void showCommentsBox(object sender, EventArgs e)
    {
        RadioButtonList myRadio = (RadioButtonList)sender;
        Panel Panel1 = (Panel)ListView1.FindControl("Panel1");

        if (myRadio.SelectedValue != "0")
        {
            Panel1.Visible = true;
        }
        else
            Panel1.Visible = false;
    }

Any help on how to approach this is appreciated.

Thanks!

Combining Ajax scripts

afache — Tue, 24 Nov 2009 17:24:36 GMT

I was trying to combine ajax scripts but I got the following error:

The resource URL cannot be longer than 1024 characters.
If using a CompositeScriptReference, reduce the number of ScriptReferences it contains,
or combine them into a single static file and set the Path property to the location of it.

I have a script managers and two scriptProxyManagers that contain a subsets of the references. Is it acceptable to do this? Would it produce the same efficient behavior I am expecting?

Sys.WebForms.PageRequestManagerServerErrorException: The request timed out while constructing the request XML.

patientd1 — Tue, 24 Nov 2009 16:42:32 GMT

I keep getting this error if I keep my page open for more that a few minutes. Please let me know how I can get rid of this error.

"Line: 4723
Error: Sys.WebForms.PageRequestManagerServerErrorException: The request timed out while constructing the request XML."

I created this page using ASP.Net and C#. There is not line 4723 in my code.

I am using AjaxControlToolkit, ScriptManager, Chart and updatepanel on this page.

UpdatePanel.Update() performance questions

wilson777 — Thu, 19 Nov 2009 13:15:43 GMT

Hi guys,

I use UpdatePanels in my webforms so I can make updated without page refreshing. I set the UpdateMode="Conditional" so I can trigger the update in C# code behind.

Just a question about performance, if I have two UpdatePanels in different sections of my webform, when I do something like this in my code:

UpdatePanel1.Update();

UpdatePanel2.Update();

UpdatePanel4.Update();

... will this trigger three postbacks or will it batch them up and update all panels at the same time with one postback?

If the former, is there anyway to get all panels to update at the same time but still maintaning the ability to trigger them from code?

Thanks and regards,

Wilson.

Entire Page Wrapped in UpdatePanel

G0ggy — Mon, 23 Nov 2009 13:21:23 GMT

Hi all,

I've been tasked to sanity check a page that is causing users problems in that they are submitting data via an input, but they are clicking the submit button a number of times as they cannot see anything happen when they submit their data.

On checking the code I can see that the author has wrapped the entire page in an UpdatePanel, including all the ObjectDataSource controls, everything.

Is this good practise? I thought the idea of the UpdatePanel's was to create small areas of input and data output without posting the whole page back to the server.

If I could get your suggestions and opinions please?

TIA.

wh r ASP.NET 3.5 Ajax Extensions installed to?

guenavan — Tue, 17 Nov 2009 11:07:07 GMT

Where are the ASP.NET 3.5SP1 Ajax Extensions (and their javasript files) are installed
(from VS2008) setup)?
i.e. situated after install?

For ex., ASP.NET 2.0 AJAX Extensions 1.0 are installed in:
%ProgramFiles%\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\v1.0.61025\MicrosoftAjaxLibrary\System.Web.Extensions\1.0.61025.0

Gridview -> Checkbox -> Button (AJAX ?)

wulfgarpro — Tue, 24 Nov 2009 05:34:58 GMT

Hi,

I have a GridView with a column that has check boxes. A button is also present (outside of the GridView) .. but until a checkbox is selected it should be non-visible.

In the case that a checkbox .. or multiple checkboxes are selected the button should become visible (and hopefully I can extract data (GUI) concerning the checked rows - irrelevant for now).

I need to achieve this without any postbacks .. upon which selection of the button will enable me to perform some SQL.

ajax slideshow extender - slideshow on loading seems slow ?

prontonet — Mon, 23 Nov 2009 20:33:32 GMT

Hi,

I am using the ajax slideshow extender but it seems a bit slow sometimes to start, even locally.

I am using the web service and this gets the images drom a directory on my server.

In the file are 40 images. Does the control have to download each image before it starts ?

is there anyway to make it operate quicker?

thanks

Concerns with new AJAX loader and MVC ajax

Nairb — Thu, 29 Oct 2009 17:14:03 GMT

The new on-demand loading system in Preview 6 is great, but has some drawbacks when interacting with the MVC AJAX library. Specifically, for MVC AJAX forms to work, quite a few ajax files need to be downloaded. Before we would just include the MicrosoftAjax.js and MicrosoftMvcAjax.js files and everything would be fine. Since MvcAjax requires various parts of the main AJAX code on every page with an MVC ajax form I have to manually include other scripts to get things to work.

Is there a plan that will fix this in the near future? Are people aware of the problems? What I'd like to see is the following:

MicrosoftMvcAjax becomes a component of the full ajax library that can be loaded through Sys.require.
Using Ajax.BeginForm for an AJAX form automatically calls Sys.require to pull in the needed library on page loading.

Is anyone else running into this issue? Is there a planned solution?

autocomplete extender issues

fsubob2003 — Mon, 23 Nov 2009 18:24:08 GMT

I keep getting this error and I dont know why. I have referenced 3.5 and I remove the references to 1.0.

Then when I build the project it readds the references to 1.0 by itself and then gives me this error.

Error 29 Indirect reference is being made to assembly System.Web.Extensions version 3.5.0.0, which contains 'AjaxControlToolkit.AutoCompleteExtender'. This Project references a prior version of System.Web.Extensions version 1.0.61025.0. To use 'AjaxControlToolkit.AutoCompleteExtender', you must replace the reference to System.Web.Extensions with version 3.5.0.0 or higher. C:\VSSWork\LASPBS_Master\LASPBS_Master\bingotester.aspx 1 1 C:\...\LASPBS_Master\

I am in vs2005 version 2.0

Any help would be much appreciated.

By the way the rounded corners extender works without any problems... very strange.

                        </SelectedItemTemplate>
                    </asp:ListView>

If I comment out the CollapsiblePanelExtender then the insertion works. The issue is, the CPE either emptys the txtInsertComments textbox or points to an empty txtInsertComments textbox in other ItemTemplate. This ListView is a nested ListView.

Any suggestion is much appreciated.

Combine multiple aspx pages into one

vicjee — Mon, 23 Nov 2009 15:46:11 GMT

Hi.

I am very new to asp ajax and have been stumped by a design issue and need some advice.

Here's my problem:

I currently have a display page (Page A) which lists all the reports I have in a database in a grid view.

Each record in the grid contains a link to a print page (Page B) which prepares a print page for the report based on a parameter (id). Page B accepts only one input parameter and generates one print page for a selected report.

I want to add a feature to Page A which will get all the reports from the database, use Page B to generate the print versions of the reports and display them all in one page.

How should I go about to implement this feature?

thanks.

error!!

myoko — Mon, 23 Nov 2009 06:16:25 GMT

Dear All Members

In most of websites,I see the "Please wait while saving...." with loading image while I press save button.
I heard that it is created with Ajax or Jquery(and I'm a little familiar with Ajax).
I also want to do like that and I have tested like that
---------------------------------------------------------------------------------------------------------------------------
<asp:UpdatePanel ID="UpdatePanely" runat="server">
        <ContentTemplate>
   <asp:TextBox ID="txtText" runat="server" /><br />
   <asp:Button ID="btnSaving" runat="server" OnClick="btnSaving_Click" Text="Saving" />
        </ContentTemplate>
        </asp:UpdatePanel>
        <asp:UpdateProgress ID="UpdateProgressy" runat="server">
           <ProgressTemplate>
                <img src="../image/loading.gif" alt="loading"/>
                Please wait ......
            </ProgressTemplate>
        </asp:UpdateProgress>
---------------------------------------------------------------------------------------------------------------------------
In .aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
        System.Threading.Thread.Sleep(2200);
}

protected void btnSaving_Click(object sender, EventArgs e)
{
        txtText.Text = DateTime.Now.ToLongTimeString();
}
---------------------------------------------------------------------------------------------------------------------------

It shows "Please wait ......" and refresh the UpdatePanel,not the entire page.
How can I do to refresh entire page when I press the "btnSaving" button and before refreshing the page,I want to show "Please wait ......".

Thanks .....

dynamic accordian

craigmacca24 — Wed, 18 Nov 2009 15:37:37 GMT

Hi I am loadin the accordian dynamically, each pane will load a seperate usercontrol, what i want to do is not load all the controls on page load, but when the pane header is clicked.

any ideas how i would do this?

if (!Page.IsPostBack) {
               AccordionPane ap1 = new AccordionPane();
               ap1.ID = "1";
               ap1.HeaderContainer.Controls.Add(new LiteralControl("Pane 1 Header"));
               ap1.ContentContainer.Controls.Add(new LiteralControl("content 1"));
               //this above will load a usercontrol instead of a literal

               AccordionPane ap2 = new AccordionPane();
               ap2.ID = "2";
               ap2.HeaderContainer.Controls.Add(new LiteralControl("Pane 2 Header"));
               ap2.ContentContainer.Controls.Add(new LiteralControl("content 2"));
               //this above will load a usercontrol instead of a literal

               acc1.Panes.Add(ap1);
               acc1.Panes.Add(ap2);
           }
