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();
        }
    }

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>

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">
