Example
The following example demonstrates how to use the RestoreTab event to handle initializing de-serialized MdiTab objects.

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.
