#311 – Giving Focus to a Control, Part II

You can give focus to a specific control at run-time using the Keyboard.Focus static method.  You can also give focus to any control that inherits from UIElement using the control’s Focus method.

		public MainWindow()
		{
			this.InitializeComponent();

            this.Loaded += new RoutedEventHandler(MainWindow_Loaded);

		}

        void MainWindow_Loaded(object sender, RoutedEventArgs e)
        {
            // On startup, set focus to first TextBox in window
            txtFirst.Focus();
        }

The difference between these two methods is:

  • Keyboard.Focus just sets keyboard focus
  • UIElement.Focus tries to set keyboard focus.  If the control fails to get keyboard focus, the method sets logical focus to the control
