Solution

  • You can use the beginRequest and endRequest client side events of the PageRequestManager to display a "please wait" UI.

    Sys.WebForms.PageRequestManager.instance.add_beginRequest(beginRequestHandler)

    Sys.WebForms.PageRequestManager.instance.add_endRequest(endRequestHandler)

    See here for more information. There are examples for each event.
