I have a fairly complex page with Multiple Update Panels and I usually have a RadGrid that when somebody selects an item, it updates a Form with the details. I've tried putting the Ajax Loading Panel and Manager on this page and other pages and I just don't think I'm using it right. I know I select a control that initiates the request, then I choose the control or controls that get updated, but time after time I get different Javascript error message stating things like:
Microsoft JScript runtime error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_MainContent_ctl00_MainContent_RadAjaxProjectPanelPanel'. If it is being updated dynamically then it must be inside another UpdatePanel.
or something similar...I've seen the examples, but I guess what I am looking for is a straight forward, Step 1, Step 2, Step 3...because apparently whatever I am doing is not working.
We are using the latest version of the Tools. We just moved from using the Trial/Demo software to the Live version. Visual Studio 2010, .NET 4.0(ASP.NET/Ajax of course)
I have been successful getting the RadGrid and Comboboxes working. I would really like to get the Loading panel working soon.
thanks
