Error handling with RadAjaxManager

[Suresh]

I am using RadAjaxManagerProxy in my user control and RadAjaxManager in the master page and a RadAjaxLoadingPanel. When an error occurs server side, the loading panel hides and does not show any error message. How can I show an error message when an ajax request fails.

Hi Suresh,

You could check out the Error Handling For Ajax Requests help article below for handling errors when ajax is enabled. Additionally, you could implement some custom logic by wrapping the code that throws an error in try-catch block and showing the error message.

<script type="text/javascript">
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);

function EndRequestHandler(sender, args) {
        if (args.get_error() != undefined) {
            var objError = args.get_error();
            args.set_errorHandled(true);
            showMessage({ messageType: 'error', message: objError.message });
        }
    }
</script>

Above script did it for me, Thanks.
