Gridview inside Webpart in asp.net

smithspd — Fri, 01 Jan 2010 05:00:00 GMT

Hi

I am trying to read the data from XMLDataSource into a gridview (in asp.net). It works when I perform below logic:
Dim ds As New DataSet()
            ds.ReadXml(Server.MapPath("LoadData.xml"))
            GridView1.DataSource = ds.Tables(0)
            GridView1.DataBind()
and I hardcoded the resultant hyperlinks inside the GridView with some name using the following exp: (and it works)
<asp:TemplateField HeaderText="Address">
           <ItemTemplate>
             <a href='<%#XPath("EMAIL")%>'><%#XPath("NAME")%></a>
         </ItemTemplate>
         </asp:TemplateField>

But when i embed the griview inside a webpart , configure the datasource, I am not able to read the data from the XMLDataSource. I get the following error:
The DataSourceID of "GridView1" must be the ID of a control of type IDataSource. A control with ID "XMLDataSource1" could not be found.
It would be great if you can help me with a solution to this

Thanks

WebPartZone styles: rendered inline or rendered in the header - how do I choose?

bepnewt — Wed, 02 Dec 2009 05:00:00 GMT

Background:

I'm working on a site that has 1 page in it with a user control that contains a WebPartManager and 2 WebPartZones. The WebPartZones have a lot of style information defined such as MenuLableHoverStyle, MenuVeryHoverStyle, TitlebarVerbStyle, etc.

The way it is now, when the HTML is rendered, the styles are inline in each of the HTML elements that are created for the WebParts. Everything works fine.

I'm converting the site to use a MasterPage. When I put the page into a MasterPage, the styles are now rendered at the top of the page inside STYLE tags and each of the elements is given a classname that matches up with style definitions in the STYLE tags. This shouldn't be a problem, and it looks fine in Firefox and Chrome, but not in IE(8). IE8 is ignoring the style definitions that are now in CSS at the top of the page.

I'm not asserting that the MasterPage is what is causing this. That just happened to be what I was doing when the rendering change happened. I also fixed some bad HTML at the same time involving mismatched tags, etc.

From my research, this is what I've decided is the issue:

The classnames that are created for the styles all start with "_" ( underscore character ). Based on multiple things I read, this is not a legal character to start a class or ID name with and IE is respecting this "rule" by not applying the styles defined in the STYLE tags to the elements.

I use the Developer Tools built into IE8 and remove the "_" from one of the class names and from the style definition and *poof*, it renders with the correct style. I can also get it to use the styles if I change the Browser Mode to IE7 and change the Document Mode to Internet Explorer 7 Standards.

What I would like to do:

I would like to either:

Force the styles to render inline like they used to before the change to a MasterPage
Force the classnames NOT to start with an "_" character

Is there any way to do this? Or, if my research is flawed, do you have any insight on how to get IE8 to render the defined styles in the WebPartZone?

More information about the site:

This is just random information that may or may not help.

The site is being developed in VS 2008.
The solution has been upgraded from a VS 2005 site at some point.
The web site IS as "Web Site" not a "Web Application".
The WebPartManager and WebPartZone controls are from the System.Web (2.0.0.0) assembly which is in the GAC.
The WebPartManager is ALWAYS in WebpartManager.BrowseDisplayMode.
Personalization is NOT enabled on the WebPartManager.
I tried using the CSSClass property of the various WebPartZone properties. I created my own classes and put them in a Style Sheet, but that didn't work.

Any help is appreciated. I had to revert this page back to not use our MasterPage for now, but would really prefer it to be converted.

Thanks,

-BEP

Memory consumption is high while using WebParts

kadam_suresh — Tue, 02 Jun 2009 04:00:00 GMT

Hi All,

I am using web parts in a page which can be customized by user deleting/adding web parts. Here the problem is when a web part is added memory is increasing, but when a web part is deleted memory is not decreasing. I think WebPartManager.DeleteWebPart is deleting only from the view not releasing the memory allocated to web part instance. Due to this site is becoming slow over a period of time.

If any one already faced the same scenario, please suggest me in optimizing the memory usage.

WebPartZone and WebPartManager In Mozilla

bbalavikram — Wed, 22 Apr 2009 04:00:00 GMT

All,

I am using WebPartZone and WebPartManager in my application. It worked all fine in IE7 but not in Mozilla. Searching internet lets me know that this is the issue of .Net framework. I also get a work around for this with the .Net Preview version here which works fine.

Is there an official version of the .Net Preview framework which I can use in my application. The Application is for a critical client, hence I do not want to take wrong chances? OR
Is there a better suggested work around ?

Urgent help needed. Please.
