Hi,

Here is a code library submission which demonstrates the requested functionality. Go through it and see if it is helpful.

Thank you for your help but i already tried out and this is not working for me :-(

I have Version 2008.1.619 of Rad Controls for ASP.Net Ajax.
In this javascript code the CloseButton object is always null !!!

var CloseButton = document.getElementById("CloseButton" + oWnd.Id);


Here is the Code :

     function openProduktDetailsWindow(ProduktID,ProduktFamilieID)
     {
        var oWnd = radopen("<%= HttpContext.Current.Request.ApplicationPath %>/ProduktDetails.aspx?ProduktID=" + ProduktID + "&ProduktFamilieID=" + ProduktFamilieID, "ProduktDetailsRadWindow1");
        oWnd.Id = "ProduktDetailsRadWindow1";
        oWnd.add_close(OnClientclose);
        oWnd.setSize (1000, 800);
        oWnd.Center();
       
        ConfirmClose("ProduktDetailsRadWindow1");
    }

    function ConfirmClose(WinName) {
        var oManager = GetRadWindowManager();
        var oWnd = oManager.GetWindowByName(WinName);
        //Find the Close button on the page and attach to the
        //onclick event
        var CloseButton = document.getElementById("CloseButton" + oWnd.Id);
        CloseButton.onclick = function() {
            CurrentWinName = oWnd.Id;
            //radconfirm is non-blocking, so you will need to provide a callback function         
            radconfirm("Blaaa!", confirmCallBackFn);
        }
    }
   
    function confirmCallBackFn(arg) {
        if (arg == true) {
            var oManager = GetRadWindowManager();
            var oWnd = oManager.GetWindowByName(CurrentWinName);
            oWnd.Close();
        }
    }

The reason this error accours is that the close button in the window object has no ID.
The property id is empty :-(

I made a screenshot in FireBug:

Hello Alaeddin Gedik,

Indeed, the solution that Shinu posted is for RadWindow for ASP.NET and not for ASP.NET AJAX. In RadWindow for ASP.NET AJAX, you need to override the closing functionality:
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik"%> 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
 
<html xmlns="http://www.w3.org/1999/xhtml" > 
<head runat="server">  
    <title>Untitled Page</title> 
</head> 
<body> 
    <form id="form1" runat="server">  
    <asp:ScriptManager ID="ScriptManager" runat="server"></asp:ScriptManager> 
    <div> 
    <script type="text/javascript">  
       function openWin()  
       {  
            var oWnd = window.radopen("http://www.google.de","test");  
       }  
    </script> 
    <input type="button" value="OpenWin" runat="server" id="Button1" onclick="openWin()">  
    <telerik:RadWindowManager ID="RadWindowManager1" runat="server">  
    </telerik:RadWindowManager> 
    <script type="text/javascript">  
    TelerikTelerik.Web.UI.RadWindow.prototype.oldClose = Telerik.Web.UI.RadWindow.prototype.close;  
    Telerik.Web.UI.RadWindow.prototype.close = function()  
    {   
        var answer = confirm("Are you sure?");  
        if(answer)  
        {  
            //call the old closing method if needed
            this.oldClose();  
        }  
          
    }  
    </script> 
    </div> 
    </form> 
</body> 
</html>

Thanky you very much!
This worked with the default confirm dialog but not with radconfirm.

The radconfirm messagebox appears but you cant close it !

Cheers

Hello,
with this solution the confirm dialog appears for each radwindow !!!

For example if you have a grid on your page and if you click the delete button in the radgrid, the radconfirm dialog appears. Now if you click "No/Close" the javascript confirm dialog apears ;-) funny


Any solutions?

The RadWindow.Close method is overriden, so this is an expected behavior.  Keep in mind that RadGrid uses the RadWindow scripts when the confirmdialogtype  is RadWindow .
If you want to show the confirm dialog only for a particular window you should write some additional JavaScript, e.g.
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik"%>    
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">    
    
<html xmlns="http://www.w3.org/1999/xhtml" >    
<head id="Head1" runat="server">     
    <title>Untitled Page</title>    
</head>    
<body>    
    <form id="form1" runat="server">     
    <asp:ScriptManager ID="ScriptManager" runat="server"></asp:ScriptManager>    
    <div>    
    <script type="text/javascript">     
       var windowWithConfirm = false;  
       function openWinWithConfirm()     
       {     
            windowWithConfirm = true;       
            var oWnd = window.radopen("http://www.google.de","test");     
               
       }     
       function openWin()     
       {     
            var oWnd = window.radopen("http://www.yahoo.com","test");     
       }     
    </script>    
    <input type="button" value="OpenWinWithConfirm" runat="server" id="Button1" onclick="openWinWithConfirm()"/>     
    <input type="button" value="OpenWithoutConfirm" runat="server" id="Button2" onclick="openWin()"/>     
    <telerik:RadWindowManager ID="RadWindowManager1" runat="server">     
    </telerik:RadWindowManager>    
    <script type="text/javascript">     
    Telerik.Web.UI.RadWindow.prototype.oldClose = Telerik.Web.UI.RadWindow.prototype.close;     
    Telerik.Web.UI.RadWindow.prototype.close = function()     
    {      
        if(windowWithConfirm == true)  
        {  
            var answer = confirm("Are you sure?");     
            if(answer)     
            {    
                //call the old closing method if needed   
                this.oldClose();    
                windowWithConfirm = false;    
            }     
        }  
        else  
        {  
                this.oldClose();     
        }  
          
             
    }     
    </script>    
    </div>    
    </form>    
</body>    
</html>
