Popup extender “frozen” on code-behind exception

问题

In a C#/ASP.NET project, we're using an ajax modalpopupextender to display a "Processing..." message to the users. We're displaying it using a Javascript call in the code of the ASP.NET page. Then, in the code behind, we're doing some database operation, and hide again the popup using "popup.hide();"

The problem is that when an exception occurs in the code behind, the popup is still displayed and the application does not handle errors as per the "customErrors" tag of the web.config.

Any idea on how to deal with this kind of issues?

Thanks, David

Can you wrap the code you are running in a try catch and make sure you call in the finally the popup.hide?
