How to Catch exception for GridView control?Hi,
I placed a Gridview control on a ASP.NET 2.0 page and enabled the "Delete", "Edit" . I want to do "Try Catch" on "Delete" and "Edit" button in the GridView but don't find the place to put the code. Please help. Thanks! Kai You will have to handle the Page level Error event:

Thanks for your help. I went to the > http://msdn2.microsoft.com/en-us/library/ed577840.aspx and use the code: private void Page_Error(object sender, EventArgs e) { Response.Write("An application error has been logged."); ApplicationSpecificErrorLogger(Server.GetLastError().Message); Server.ClearError(); } I found error for not recogonizing "ApplicationSpecificErrorLogger". I looked it in help file and not find the class. What I did is using GridView to display "Phone Number", and a front user can edit the number. I setup phone number datatype vchar(20). When user enter longer than 20 characters, error message will show. Try/Catch cannot catch the exception.
