WPF Lost-Focus issue in same control

Question

I have a small problem with focusing in .net/wpf. I have written a custom user control which contains a TextBox and a SearchButton. The user-control has a lost focus event, which validate the content of the textbox if the focus is leaving. But now I have the problem, if I click on my search button, the lost focus event of the user control gets fired, even if I click on the button in the custom user control. (The button additionally has the option TabStop="False":

Custom-User-Control design

The problem is, that I don't want to fire the event if I click on the button.

Set

Focusable="False"

of your search button and the TextBox will not lose the focus because the button doesn't get the focus.

You can Do this Check in Event like this

protected void LostFocusEvent(object sender, RoutedEventArgs e)
{
    if(textBox.Text.Length>0)
    {
      // if there is any character in TextBox
    return;
    }

   // your validation Code goes here
}

But the textbox validation is independent from clicking the Button – BendEg Jul 18 '15 at 16:05
