Is there a way to detect when an update panel is done refreshing?

问题

Is there a way to detect when an update panel is done refreshing? I want to fire some javascript methods when the update panel is finished.

Perhaps via the UpdateProgress control?

You can use:

Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);

function EndRequestHandler(sender, args) {
   // do what you want here
}

Of course, this will caputure every AJAX EndRequest call so you'll have to make your EndRequestHandler function see what has been requested or play with BeginRequestHandler. More info here.
