  Hi,
  
  I have a toolbar with a button on it like this:
  
  

      <telerik:RadToolBar Grid.Row="1"

                 OverflowButtonVisibility="Visible"

                 MouseLeftButtonDown="UIElement_OnMouseLeftButtonDown">

   

   

              <telerik:RadButton x:Name="newButton"

                  Command="{Binding CreateNewCommand}">

                  <StackPanel Orientation="Horizontal">

                      <Image Source="../NewDocument.png"

                          Stretch="None"/>

                      <TextBlock Text="New"

                          VerticalAlignment="Center"

                          Margin="5,0,5,0"/>

                  </StackPanel>

              </telerik:RadButton>

  ...

  
  
  This xaml is part of a user control called MainPage which gets loaded in a user control called Shell, which gets loaded in App.xaml
  Client asked to have keyboard shortcuts for my RadToolbar commands, like (Ctrl+Shift+S) for the save button.
  I know RadToolbar doesn't support this yet, so I started coding a solution which handles key down evens in the user control "Shell":
  
  

          public Shell()

          {

              InitializeComponent();

              AddHandler(UIElement.KeyDownEvent, new KeyEventHandler(Shell_OnKeyDown), true);

          }

   

          private void Shell_OnKeyDown(object sender, KeyEventArgs e)

          {

              if (Keyboard.Modifiers == (ModifierKeys.Control | ModifierKeys.Shift) && e.Key == Key.S)

              {

  //do something

              }

          }

  
  
  This works well in IE. In all the other browsers I have to first click somewhere inside shell, and only then will the keyboard shortcuts work. 
  I think it has to do with the fact that no control has the focus.
  All I have on the MainPage user control, when it's initially loaded is a toolbar with some buttons.
  I've tried setting the focus on a RadButton from the toolbar explicitly, in the LoadedEvent of the user control, but it doesn't work.
  
  Any thoughts on how I could accomplish this?

  Hi Christian Burkhardt,
  
  You can try focusing the MainPage control when the Shell is loaded like so:
  

  private void Shell_Loaded(object sender, RoutedEventArgs e)

  {

      System.Windows.Browser.HtmlPage.Plugin.Focus();

      mainPageControl.Focus();

  }

  That should do the trick.
  
  All the best,

  Hey, 
  
  Thanks for the quick reply, I tried your code, but doesn't seem to fix the problem  :( 
  Have you tried this in a sample and it works for you?
