Only focus a Textbox when it's double clicked

Question

Is there a way to only focus a Textbox when it's double clicked? Normally it gets focused when it's clicked once. I want to be able to DragMove(); the Window if the Textbox is clicked and if it's double clicked I want to be able to write into it.

I've already tried this solution: TextBox readonly "on/off" between "double click and lost focus events" in wpf But it still focuses the Textbox.

I want to do the same thing with a Richtextbox I hope one solution works for both.

Thank you in advance :D

I figured it out! I just had to tweak @Ohad Cohens Code a bit!

XAML

<TextBox MouseDoubleClick="TB_MouseDoubleClick" LostFocus="TB_LostFocus" Focusable="False"/>

C#

        private void TB_MouseDoubleClick(object sender, MouseButtonEventArgs e)
        {
            if (sender is TextBox tb)
            {
                tb.Focusable = true;
                tb.Focus();
            }
        }

        private void TB_LostFocus(object sender, RoutedEventArgs e)
        {
            if (sender is TextBox tb)
            {
                tb.Focusable = false;
            }
        }

The DragMove();

Can simply be achived using

private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    DragMove();
}
