Anne Chinn asked on 22 Sep 2010, 01:11 AM

I have a RadGrid that has an expand/collapse column. I have put the RadGrid in a UserControl and then placed the UserControl inside a RadWindow ContextTemplate. The TaskGrid control's expand/collapse works correctly when included in another page, but when it is embedded within the RadWindow they don't work. Nothing happens when I click on it. Any ideas?

Thanks,

Anne Chinn

<telerik:RadWindow ID="AssignTasksWnd" runat="server" ShowContentDuringLoad="true" Width="800px"

Hi Anne,

I tried to replicate the described issue in a test project by using the relevant logic from your source, but to no avail. I tried both showing the RadWindow on page load and after a button click and in both cases the expand / collapse functionality works as expected. Could you please take a look at my project and let me know what am I missing out in reproducing the error?
