Focus control for Custom User Control

I have a UserControl defined such that:

UserControl
  TextBox
  Button (Clear)

I have a GotFocus handler on the UserControl so that whenever it gets focus, it calls TextBox.Focus(). The problem I am running into is that If I click the clear button, it clears the text and then refocuses to the textbox, triggering two GotFocus events on my control. I want this to act as either:

I have played with FocusManager.IsFocusScope to no avail. Is there even a way to trigger a manual LostFocus right before I call Textbox.Focus?

In your GotFocus event you can check whether the mouse is over the clear button and whether the left mouse button is pressed, in such a case you can ignore the call to TextBox.Focus():

private void UserControl_GotFocus(object sender, RoutedEventArgs e)
{
     if ((this.clearButton.IsMouseOver && Mouse.LeftButton == MouseButtonState.Pressed) == false)
     {
         this.textBox.Focus();
     }
}
