Implementation of loaded in Ajax

Here is a script which only require div tag that needs to be displayed once ajax request will be fired:


<script type="text/javascript">
    // Get the instance of PageRequestManager.
    var prm = Sys.WebForms.PageRequestManager.getInstance();
    // Add initializeRequest and endRequest
    prm.add_initializeRequest(prm_InitializeRequest);


    // Called when async postback begins
    function prm_InitializeRequest(sender, args) {
    // get the divImage and set it to visible
    var panelProg = $get('divImage');
    panelProg.style.display = '';


    // Disable button that caused a postback
    $get(args._postBackElement.id).disabled = true;
    }


  </script>
