Example

[Visual Basic, C#, C++] The following example initially creates a TabControl with three TabPage. This example uses the RemoveAt method to remove tabPage1, which is specified by its index, from the tabControl1 controls collection. Notice that the TabPages property gets the tabControl1 controls collection to add and remove tab pages from this collection.

[Visual Basic, C#, C++] Use the System.Drawing and System.Windows.Forms namespaces for this example.
