How do I stop WPF KeyDown events from bubbling up from certain contained controls (such as TextBox)?

Question

My program is quite large, and uses WPF, and I want to have a global shortcut key that uses \'R\', with no modifiers.
There are many controls such as TextBox, ListBox, Combo

Answer 1

There is an event when you handle KeyDown event and it should pass you a KeyEventArgs. From there you can set the Handled to true so that it won't bubble up.

Sample

private void TextBoxEx_KeyAction(object sender, KeyEventArgs e)
{
  e.Handled = true;
}
