Remarks

When you change the focus by using the keyboard (TAB, SHIFT+TAB, and so on), or by calling the Select or SelectNextControl(Shape, Boolean, Boolean, Boolean, Boolean) method, focus events occur in the following order:

Enter

GotFocus

Leave

LostFocus

When you change the focus by using the mouse or by calling the Focus method, focus events occur in the following order:

Enter

GotFocus

LostFocus

Leave

For more information about how to handle events, see Consuming Events.

注意

Do not try to set focus in the LostFocus event handler. Doing so can cause your application or the operating system to stop responding.

Examples

The following example shows how to respond to the GotFocus event in an event handler. This example requires that you have a RectangleShape control named RectangleShape1 on a form.

Private Sub RectangleShape1_GotFocus(
  ) Handles RectangleShape1.GotFocus

    RectangleShape1.SelectionColor = Color.Red
End Sub

private void rectangleShape1_GotFocus(object sender, System.EventArgs e)
{
    rectangleShape1.SelectionColor = Color.Red;
}
