I am trying to upload files via a RadGrid that is Ajaxified. Based on the demos, I am trying to disable Ajax when the "Insert" button is clicked when trying to add a new row to the grid. The ClientEvents-OnRequestStart event is never firing.

Does anyone have any ideas what I might be doing wrong?

Here is the code for my aspx page:

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<telerik:RadScriptManager ID="radScriptManager" runat="server" />

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

function conditionalPostback(sender, args) {

alert('ConditionalPostBack');

var theRegexp = new RegExp("\.RadButtonInsert$", "ig");

if (args.get_eventTarget().match(theRegexp)) {

var upload = $find(window['RadUpload1']);

if (upload.GetFileInputs()[0].value != "") {

args.set_enableAjax(false);

}

</script>
