RadTabControl is a container for multiple tab items. Each tab item represents an instance of the class Telerik.Windows.Controls.RadTabItem and it is the only building block of the tab control. The tab control is made of two parts: the tab header and the content area. The tab headers are always visible at the left, top, right or bottom of the tab control, while the content area is visible only when the tab item is selected. For more information see the visual structure topic of the tab control.
Here is a list of most important tab item features:
The appearance of tab items can be changed using either styling or templates. You can set the specific templates using the ControlTemplate, HeaderTemplate or ContentTemplate properties.
Populate your tab control with tab items using one of the following approaches: declaratively, programmatically, using data binding or using Blend.
Control the way the tab strip is positioned using the TabStripPosition property of the RadTabControl as shown in the How To section of the documentation.
