Question

I have a control where is about 100 hundred TextBoxes, and I need for each of them have binded event to GotFocus event (where I select all text).

I cant use EventSetter as in WPF, so what do you use to bind event in style?

Answer 1

You’ll have to subclass the TextBox class and then use that in all your code.

You can then put the GotFocus event handler in that subclass, otherwise you’d have to add the GotFocus event handler to all your code.

public class MyTextBox : TextBox
{
    protected override void OnGotFocus(RoutedEventArgs e)
    {
        // Add your code in here
        base.OnGotFocus(e);
    }
}

Then in your XAML you’d have:

<my:MyTextBox ..... />
