In your textbox declaration, add the following handler:
PreviewKeyDown="KeyDownHandler"
In the codebehind, you will add the code:
private void KeyDownHandler(object sender, KeyEventArgs e)
{
//
}WPF allows you to preview commands, so there is no need to use a keypress to validate the item because you can cancel it here by setting
e.Handled = true;in response to your test.Deja View - the feeling that you've seen this post before.
