RadMultiPage acts as a container for page views. Each PageView control in turn contains child controls such as buttons and text boxes. You can programmatically show and hide a particular PageView on the sever and client side.

The MultiPage and the TabStrip controls are natively integrated. All you need to do is set MultiPageID property of the tabstrip to the ID of the respective multipage instance. If the controls are not inside the same naming container, you can use the multipage UniqueID value.
