The TabStrip control doesn't allow you to add controls to a Page on the TabStrip, instead it's up to you to make certain sets of control visible or invisible depending on which Tab is selected.

For what you want, you should look at using the Microsoft Tabbed Dialog control instead, it allows you to add controls to the Pages of the TabStrip without having to do any manipulation at Runtime.
