I copied the markup for an asp:UpdateProgress control from one website to another and forgot to change theAssociatedUpdatePanelID property.
This obviously threw an error, so I corrected the property and although it is now working as expected, when I run the page through Visual Web Dev, intitally the page tab (in Internet Explorer) states "No UpdatePanel found for the AssociatedUpdatePanelIDwith the original incorrect UpdatePanelID".
What is even stranger is that even if I completely remove the UpdateProgress control from the markup and re-run the page, the same message is appearing in the IE tab.
How can I fix this?
I have tried adding the UpdateProgress back into the markup and setting the property in code behind on the first line ofPage Load event.
