We did not implement our own error handling for RadAjax, as the MS AJAX framework already takes care of that. During partial-page rendering, you can handle errors by doing the following:
· Set the AllowCustomErrorsRedirect property, which determines how the custom error section of the Web.config file is used when an error occurs during an asynchronous postback.
· Handle the ScriptManager control's AsyncPostBackError event, which is raised when there is a page error during an asynchronous postback.
· Set the AsyncPostBackErrorMessage property, which is the error message that is sent to the browser.
