Base. On Got Focus(EventArgs) Method

Protected Overrides Sub OnGotFocus (e As EventArgs)
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnGotFocus method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
