Syntax

[TelerikToolboxCategory("Navigation")]
public class RadTabItem : HeaderedContentControl, ISelectable, IRadTabItem
Remarks

The RadTabItem class is the default item of the RadTabControl. The TabItem appears in the TabStrip of the TabControl while the contents of its System.Windows.Controls.ContentControl.Content property are shown when the Tab is selected.

When tabs are inserted into the TabControl the last Tab to have its IsSelected property set to true would be selected.

You can change the look of the Control by setting the Theme, Style or Control Template properties. To change the look of all the TabItems in a TabControl, use the ItemContainerStyle and ItemContainerStyleSelector

The RadTabItem is not meant to be used on its own but as item of the RadTabControl. The TabItems will be automatically created if other items are inserted in the RadTabControl.

Please note that the TabStripPlacement and TabOrientation properties are set by the TabControl and as such are read-only.
