User Controls in Datagrids

[sboot]

Hi again,
I have developed user control that I can put on a page and it works no problem.
However, when I pull data out of a dataset into a datagrid and put user control within a template column, the control displays, but doesn't work; as in it cannot keep its state when it is supposed to do something.

This is my templateColumn...

Code: Select all

 
<asp:TemplateColumn headertext="Title">
         <ItemTemplate>
          <foxford:dbImg runat="server" imageid='<%# Container.DataItem("imgId") %>' alternatetext='<%# Container.DataItem("title") %>' /><br />
          <asp:hyperlink runat="server"
               text='<%# Container.DataItem("title") %>'
               href='<%# Container.DataItem("url") %>'
               target="_blank" />
         </ItemTemplate>
</asp:TemplateColumn>

As you can see, the control in question is my <foxford:dbImg> control which should do something whenever a button is pressed within it.

For your information, my control displays an image from a database with an "Edit" button. When the button is clicked it then should display a file upload field.

Any ideas?

Thanks, Steve

Off the top of my head, I think this is because when your control is clicked in the datagrid the postback cannot find the usercontrol because is is nested in the template. I dont know if this is gonna work, but look into the FindControl() method. Also what ?might? be if use is the OnItemDatabound event of the datagrid and casting your user control.

Hope that is of some help

Thanks for your reply. It was useful, however didn't cure my problem hehe.

By my usual method of fixing bugs by sheer random acts of programming, I decided to stick if statements around my BindDataGrid method to see what happens...

Code: Select all

 
 if not isPostBack then
  BindDataGrid()
 end if

...and lo and behold, the controls started working! Yay
