In other controls I have used in the past, there was a titlebar (or in yourcase header) DialogEventHandler that I could call to do something when someone left clicks the Header to drag the window. The reason I need this is because I have an HTMLplaceholder inside another window and due to the Silveright/htmlplaceholder iframe restrictions, cannot hide itsellf behind the other Window. I would like to set the HTMLplaceholder part not visible when the other window is selected... Can someone please point me where I should be looking for this if there is such a thing? I tried the Drag Events, but these do not seem to trigger

Thanks in advance

Added information..... I seem not to be able to use the GotFocus events at all for some reason... I have a breakpoint and it is never even hitting the GotFocus event??  Trying to do GotFocused on the  Rad Window with Silverlight Header in Code below...

Code :

using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Net;  
using System.Windows;  
using System.Windows.Controls;  
using System.Windows.Documents;  
using System.Windows.Input;  
using System.Windows.Media;  
using System.Windows.Media.Animation;  
using System.Windows.Shapes;  
using Telerik.Windows.Controls;  
namespace RadControlsSilverlightApp1  
    public partial class MainPage : UserControl  
        #region GLOBALS  
        RadHtmlPlaceholder GoogleHolder = new RadHtmlPlaceholder();  
        RadWindow GoogleWindow = new RadWindow();  
        RadWindow Silverlight = new RadWindow();  
        public MainPage()  
        private void button1_Click(object sender, RoutedEventArgs e)  
        private void RadControlbutton_Click(object sender, RoutedEventArgs e)  
            // Make placeholder  
            GoogleHolder.Height = Double.NaN;  
            GoogleHolder.Width = Double.NaN;  
            GoogleHolder.SourceUrl = new Uri("");  
            //Make Rad Control  
            GoogleWindow.Content = GoogleHolder;  
            GoogleWindow.Header = "Google Demo";  
            GoogleWindow.Height = 300;  
            GoogleWindow.Width = 300;  
            //Make Rad Control  
            Silverlight.Content = "TEsting 123";  
            Silverlight.Header = "Silverlight Demo";  
            Silverlight.Height = 300;  
            Silverlight.Width = 300;  
            Silverlight.GotFocus += new RoutedEventHandler(Silverlight_GotFocus);  
        void Silverlight_GotFocus(object sender, RoutedEventArgs e)  
            GoogleWindow.Visibility = Visibility.Collapsed;

Hi gcoleman0828,

Thank you for contacting us.

You can try using Activated event:

Activated - occurs each time the RadWindow gets active. The event handler receives two arguments:

  • The sender argument contains the RadWindow. This argument is of type object, but can be cast to the RadWindow type.
  • An EventArgs object.
You can also use IsActiveWindow property - Gets a value indicating whether this instance is active.

I hope this information helps. I will be glad to assist you further.

Kind regards,
the Telerik team
