Hi,
This issue comes when you have a control registered as an AsyncPostbackTrigger in multiple update panels.
Try adding the following right after the script manager declaration:

JavaScript

<script type="text/javascript" language="javascript">
    Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
    function EndRequestHandler(sender, args){
        if (args.get_error() != undefined){
            args.set_errorHandled(true);
        }
    }
</script>

Refer this[^] also.
