Hi,

I think I have found a bug in the 2009 Q2 and Q3 versions. See below the code example:

    
            <telerik:RadWindow ID="win" runat="server" ReloadOnShow="true" /> 
        
            <asp:HyperLink runat="server" ID="hl" Text="Click" NavigateUrl="javascript:var w=OpenWin();" /> 
        
            <script type="text/javascript">  
        
                function OpenWin()  
        
                {  
        
                    var w = $find("win");  
        
                    w.setUrl('/Default.aspx');  
        
                    w.add_close(WinResult);  
        
                    w.show();  
        
                }  
        
                function WinResult(sender, args)  
        
                {  
        
                    alert("OK!");  
        
                    //Remove window closed handler  
        
                    sender.remove_close(WinResult);  
        
                }  
        
            </script>

When I click the hyperlink, the Window is opened with the URL '/Default.aspx'. When the Window is closed the WinResult javascript function is called.

The problem is that the Default.aspx page is loaded twice in the RadWindow. When I remove the RadWindow property ReloadOnShow ór when I remove the last line the from the javascript function WinResult "sender.remove_close(WinResult)", this problem does not occur.

From one of the Telerik experts I heard that it is actually necessary to call that remove_close method on the RadWindow object to prevent executing the script more than once. So, what can I do to prevent loading the Default.aspx page twice in the RadWindow.

Thanks,
Danny
