Hi Olo,

You can very easily refresh the RadGrid on your page when the RadWindow closes by taking advantage of the rich, built-in client-side API of the RadControls. What you can do is define a client-side event-handler for the RadWindow's OnClientClose event, which is fired when the RadWindow is closed, and then from that event handler you can call your RadAjaxManager's ajaxRequestWithTarget() function and pass in the ClientID of your RadGrid. This will cause an Ajax request to be sent to the server that target's the RadGrid, and will refresh the RadGrid when the request completes. Here is a simple example:

    
            <telerik:RadScriptManager ID="RadScriptManager1" runat="server" /> 
        
            <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server"> 
        
                <script type="text/javascript"> 
        
                    function RadWindow_Close(sender, args) { 
        
                        var ajaxManager = $find('<%= RadAjaxManager1.ClientID %>'); 
        
                        ajaxManager.ajaxRequestWithTarget('<%= RadGrid1.ClientID %>'); 
        
                    }            
        
                </script> 
        
            </telerik:RadCodeBlock> 
        
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"> 
        
                <AjaxSettings> 
        
                    <telerik:AjaxSetting AjaxControlID="RadGrid1"> 
        
                        <UpdatedControls> 
        
                            <telerik:AjaxUpdatedControl ControlID="RadGrid1" /> 
        
                        </UpdatedControls> 
        
                    </telerik:AjaxSetting> 
        
                </AjaxSettings> 
        
            </telerik:RadAjaxManager> 
        
            <telerik:RadGrid ID="RadGrid1" runat="server"> 
        
            </telerik:RadGrid> 
        
            <telerik:RadWindow ID="RadWindow1" runat="server"  
        
                VisibleOnPageLoad="true" 
        
                NavigateUrl="http://www.google.com"  
        
                OnClientClose="RadWindow_Close"> 
        
            </telerik:RadWindow>

I hope this helps. Let know if you have any further questions.
