I have a treeview on the left panel and the gridview in the content page. Both the treeview and the gridview bind to the same datasource and have the same functionality. For instance, clicking employer in the treeview and clicking the employer link in the gridview take you to the same page. All I want is when I click the employer link in the gridview, I want the gridview row command event to call the selectednodechanged event of the treeview, so that the treenode for employer has the selected node style and performs the function of hte selectednodechanged. i have tried treeview.nodes[0].select but this does not fire the selectednodechanged event.

I have a gridview ...asp 2.0 and VS 2005.The Gridview has template fields and I am using a Header Templete and an Item Template field.Within the Item template fields I am using a asp: table and within the table I am using different asp controls to bind data to the gridview
Here is the issue ...I want that each datafield should align with each other eactly i.e. symmetricaly each column wise.The problem as of now is that as each row of data is displayed in a new table and as a result each column aligns differently.How can I align the columns with each other?
<ItemTemplate>
<asp:Table>
<asp:label> ...<Eval(datafield) </asp:label>[code]....

BorderColor="White" BorderWidth="0px" Height="79px" Width="232px">
<Columns>

I have a gridview with a ButtonField. When I leave the button type as the default LinkButton, clicking that button fires the RowCommand and everything works as expected. As soon as I change the button type to ImageButton and assign an ImageUrl, clicking that button does not fire the RowCommand.

I have a GridView attached to an ObjectDataSource (returning a DataTable) in a UserControl. The code is really simple. Data comes down fine when the page is first rendered. When I click on Select or Delete (inside TemplateFields), RowCommand is supposed to fire but it doesn't, the page goes straight to Page_Load. I literally have 0 other event handlers that are set on this control and everything else in the codebehind shouldn't even fire if it's a postback. Also on postback, the Select and Delete buttons disappear. It looks like the TemplateFields are still there but they're empty. The data fields (all of two columns) post back fine.

I want to create dynamic datalist control with item template in a for loop.
Example: In my database, I have 20 Categories and 100 products. Each categories have some products. Now I want to show 20 categories all together in my page and it is not specific that categories will remain same. It can be increase or decrease. I am taking CategoryID with for loop and now I want to bind datalist according to the count of for loop.
I already implemented the dynamic templatefield which will re-created in every postback. Everytime I make a postback in the page I see no problem but when I click my imagebutton inside the gridview then the dynamic templatefield disappear.
To double check if it is really gone at all I just select the second page of the gridview using my customize paging using dropdownlist outside the gridview and the templatefield with its correct data reappear again.
I already put a variable inside the rowcommand to see if the number of columns are the same with the number of columns the gridview render together with the dynamic templatefield during debugging and it is there but cannot render that templatefield in the client.
I've created a databound gridview inside the gridview's RowDataBound I use the RowSpan property to merge cells. The grid ends up looking like this for example....
Data Data Data Button
Data Data Button
Data Data Data Button
Data Data Button
Data Data Data Button
The button is generated using a Template Field and is a standard ASP:Button. If I click a button in an unmerged row everything works as expected. If I click a button in a merged row...the sender object on the command comes back as null and no matter what I try I can't seem to fix it or get a reference to the button.
sender.CommandArgument
for example returns and empty string.
