Hi,
My master page contains web form. And web form contains user control.
User control contains combobox within UpdatePanel.
When selectedindexchange event of combobox fired, I want to fire a method at MasterPage (Client side or Server side).
Is that possible.
I added following lines of code at MasterPage.Master. But it does not work.
Breakpoint at Onload event from MasterPage was hit.

HTML

<script type="text/javascript">
    Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
    function EndRequestHandler(sender, args) {
        alert('partial postback');
    }
</script>

Is there a way?
