Question

There is a button which is clicked programmatically with code below but it stays as focused (I am not sure with terminology though). How can I get rid of that?

private void txt_addRemove_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Key == Key.Return)
    {
        btn_BC_add.RaiseEvent(new RoutedEventArgs(Button.ClickEvent));                
    }
}

Apart a fact that really wired to call a ButtonClick. What you should do, instead, at least define a Command, associate it to a button, and from this code do not call RaiseEvent, but call Command associated to that button. In practise you call a function.

What about a focus, should be enough to set esplicitly a focus to some other control on your view.

Hope this helps.
