JS beginRequest event handler

May 20, 2011 at 3:27 PM

Hi All,

I'd like to catch the beginReqest event of the PartialUpdatePanels with JavaScript, like this one on the standard UpdatePanel:

Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(beginRequestHandler);

Unfortunately this one doesn't work with PartialUpdatePanels, and I couldn't find any documentation about this issue. I did some reverse engineering though and found the add_refreshStarting function, I'm pretty sure I have to use this one just can't figure out how.


Many Thanks!
