Lose focus of button

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?

after before 

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

You could use the TraversalRequest Class to MoveFocus or explicitly set your Focus to another element.

i.e.

btn_BC_add.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));

Just in case that your button is last in the Focus order, you can try other FocusNavigationDirection options such as Previous, First, Last, Left, Right, Up, Down, .

There are a lot of ways to do what you want properly, here is one:

It's best to set the UpdateSourceTrigger to PropertyChanged and use a Command to bind the Enter key to. This should be the same command that you're Button binds to (so move your business logic to the view-model layer).

Alternatively, if this is the only Button on your form, you can set the IsDefault property to true (you'll still want to set the UpdateSourceTrigger to PropertyChanged).

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.
