Occurs when the SelectedIndex property has changed.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
When this event occurs, you can check the SelectedIndex property to determine its new value. Alternatively, you can handle the Selected event and use the TabControlEventArgs.TabPageIndex property to determine the index of the selected tab page.
For more information about handling events, see Handling and Raising Events.
The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.
To run the example code, paste it into a project that contains an instance of type TabControl named TabControl1. Then ensure that the event handler is associated with the event.
