I used RadWindow in ASP.NET and I am now trying to convert to ASP.NET AJAX and I cannot get it to work. Here is my code:
<asp:ScriptManager runat="server" ID="scriptManagerCLProxy">
<Services>
<asp:ServiceReference
path="~/WebServices/CheckFileStatus.asmx" />
</Services>
</asp:ScriptManager>
<telerik:RadWindowManager ID="RadWindowManager1" runat="server">
<Windows>
<telerik:RadWindow
id="RadWindow1"
runat="server"
showcontentduringload="false"
width="400px"
height="400px"
title="Critical Comments"
behaviors="Default">
</telerik:RadWindow>
</Windows>
</telerik:RadWindowManager>
<script language="javascript" type="text/javascript">
function CheckCriticalComments() {
var oWindow = null;
var CCFlag = document.getElementById("txtCCFlag").value;
alert("CCFlag=" + CCFlag);
if (CCFlag == "Y") {
CCFlag = "N";
radopen("CriticalComments.aspx", "RadWindow1");
}
}
</script>
All I get is an "object required" error message on the "radopen" statement.
Please help.
Thanks,

Hello Donald,
The code that you posted looks OK. How do you open the window, e.g. how do you call CheckCriticalComments()?

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
If Not Page.IsPostBack Then
If DALayer.CritialComments(FileNum) Then
txtCCFlag.Text = "Y"
End If
end if
end sub
<body class="newNormal" onload="CheckCriticalComments()" >
I have checked and txtCCFlag.text is "Y" and CCFlag = "Y"
Thanks

Hi Donald,
The reason for the problem is that you are calling your script in window.onload. Unlike ASP.NET, in ASP.NET AJAX the ASP.NET AJAX controls (like ours) are loaded on a later stage - in Sys.Application.Init. You can verify that by examining the HTML dump of a page with AJAX controls on it.
What happens in your case is that you call radopen(), but the RadWindowManager is still not fully rendered on the page hence the problem. I would suggest either to call your code with a small timeout, or better - to use the pageLoad() function. This is a native ASP.NET AJAX function and its usage is similiar to the onload event handler. The difference is that pageLoad() will be automatically called only after all ASP.NET AJAX controls are loaded on the page (you need to have ScriptManager / RadScriptManager on the page for this function to work).
More information on the subject is available in the ASP.NET AJAX documentation.
