TextBox always focused

Question

I have a window with a TextBox and a Button. I want to always focus my TextBox, but allow the user to click the button. How can I do it?

I tried it by using a LostFocusEvent, that whould check who has the focus, and if it wasn't the Button it would focus the TextBox back, but I always get a System.StackOverflowException...

This what I was using:

    private void TextLostFocus(object sender, RoutedEventArgs e)
    {
      IInputElement focusedControl = FocusManager.GetFocusedElement(this);

      if (focusedControl != btn && focusedControl != txt)
      {
        txt.Focus();
      }
    }

Is there a way to do this?

Answer 1

in the button click event you can give focus back to your text box like this.

textbox.focus();

Answer 2

Textbox.Select();

Focus is a lower level method used for custom controls. I would stick to select() or activate()

Answer 3

private void TextLostFocus(object sender, RoutedEventArgs e)
{
  ((TextBox) sender).Focus();
}

Answer 4

you could use ActiveControl Property to set focus to your text box.

    this.ActiveControl = yourTextboxName;
