Hi Mayank,

In ASP.NET AJAX environment, the ASP.NET controls (including RadControls for ASP.NET AJAX) are created after the page is loaded. The problem in your code is that the function is called before the RadWindowManager is rendered on the page. You can call the OpenWin() function from the function pageLoad in order to get the RadConfirm on pageload.

ASPX:

    
            <head runat="server"> 
        
                <title>RadConfirm</title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server" > 
        
                <telerik:RadWindowManager ID="RadWindowManager1" runat="server"> 
        
                <Windows> 
        
                </Windows>     
        
                </telerik:RadWindowManager> 
        
                <asp:ScriptManager ID="ScriptManager1" runat="server"> 
        
                </asp:ScriptManager> 
        
            </form> 
        
            </body>

JavaScript:

    
            <script language="javascript" type="text/javascript"> 
        
            function pageLoad()  
        
            {  
        
                OpenWin(); 
        
            } 
        
            function OpenWin() 
        
            { 
        
                alert('mayank1'); 
        
                radconfirm('Are you sure?', confirmCallBackFn, 330, 100); 
        
            } 
        
            function confirmCallBackFn(arg)  
        
            { 
        
                alert("Confirm returned the following result: " + arg); 
        
                if (arg == true) 
        
                    window.parent.location ="defaultCS.aspx"; 
        
                else 
        
                    window.parent.location ="default.aspx"; 
        
            } 
        
            </script>

Thanks,
Shinu.
