In dnprdnext, the tab is considered part of the tab page for determining when the Control.Enter and Control.Leave events of the System.Windows.Forms.TabPage occur. In earlier versions of the .NET Framework, the Control.Enter and Control.Leave events of the System.Windows.Forms.TabPage do not occur when focus enters or leaves a tab, but only when focus enters or leaves the client rectangle of the tab page.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The TabPage.OnEnter(EventArgs) 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.
