How to capture Ctrl + Tab and Ctrl + Shift + Tab in WPF?

What would be some sample code that will trap the Ctrl+Tab and Ctrl+Shift+Tab for a WPF application?

We have created KeyDown events and also tried adding command bindings with input gestures, but we were never able to trap these two shortcuts.

What KeyDown handler did you have? The code below works for me. The one that gives me trouble is: Alt + Tab, but you didn't ask for that :D

public Window1()
{
   InitializeComponent();
   AddHandler(Keyboard.KeyDownEvent, (KeyEventHandler)HandleKeyDownEvent);
}

private void HandleKeyDownEvent(object sender, KeyEventArgs e)
{
   if (e.Key == Key.Tab && (Keyboard.Modifiers & (ModifierKeys.Control | ModifierKeys.Shift)) == (ModifierKeys.Control | ModifierKeys.Shift))
   {
      MessageBox.Show("CTRL + SHIFT + TAB trapped");
   }

   if (e.Key == Key.Tab && (Keyboard.Modifiers & ModifierKeys.Control) == ModifierKeys.Control)
   {
      MessageBox.Show("CTRL + TAB trapped");
   }
}

Gustavo's answer was exactly what I was looking for. We want to validate input keys, but still allow pasting:

protected override void OnPreviewKeyDown(KeyEventArgs e)
{
   if ((e.Key == Key.V || e.Key == Key.X || e.Key == Key.C) && Keyboard.IsKeyDown(Key.LeftCtrl))
      return;
}

You have to use KeyUp event, not KeyDown...

Working version of Szymon Rozga answer (sorry, I can't comment). We don't look on Alt, but it's accounting can be simply added at first if

  public View()
  {
     InitializeComponent();
     AddHandler(Keyboard.PreviewKeyDownEvent, (KeyEventHandler)controlKeyDownEvent);
  }

  private void controlKeyDownEvent(object sender, KeyEventArgs e)
  {
     if (e.Key == Key.Tab && Keyboard.Modifiers.HasFlag(ModifierKeys.Control))
     {
        if (Keyboard.Modifiers.HasFlag(ModifierKeys.Shift))
           MessageBox.Show("CTRL + SHIFT + TAB trapped");
        else
           MessageBox.Show("CTRL + TAB trapped");
     }
  }

Hi you can use this on keydown event

 private void OnButtonKeyDown(object sender, KeyEventArgs e)
    {
        if(Keyboard.IsKeyDown(Key.LeftCtrl) && Keyboard.IsKeyDown(Key.Tab) && Keyboard.IsKeyDown(Key.LeftShift))
        {
           //
           // TODO: somthing here
           //
        }
    }
