Telerik.Web.UI.RadTab

Represents a tab in the Telerik.Web.UI.RadTabStrip RadTabStripcontrol.

Remarks

The Telerik.Web.UI.RadTabStrip RadTabStripcontrol is made up of tabs. Tabs which are immediate children of the tabstrip are root tabs. tabs which are children of root tabs are child tabs. A tab usually stores data in two properties, the P:Telerik.Web.UI.RadTab.Text Textproperty and the P:Telerik.Web.UI.RadTab.Value Valueproperty. The value of the P:Telerik.Web.UI.RadTab.Text Textproperty is displayed in the Telerik.Web.UI.RadTabStrip RadTabStripcontrol, and the P:Telerik.Web.UI.RadTab.Value Valueproperty is used to store additional data. To create tabs, use one of the following methods:bullet Use declarative syntax to define tabs inline in your page or user control. Use one of the constructors to dynamically create new instances of the Telerik.Web.UI.RadTab RadTabclass. These tabs can then be added to the Tabscollection of another tab or tabstrip. Data bind the Telerik.Web.UI.RadTabStrip RadTabStripcontrol to a data source. When the user clicks a tab, the Telerik.Web.UI.RadTabStrip RadTabStripcontrol can navigate to a linked Web page, post back to the server or select that tab. If the P:Telerik.Web.UI.RadTab.NavigateUrl NavigateUrlproperty of a tab is set, the RadTabStripcontrol navigates to the linked page. By default, a linked page is displayed in the same window or frame. To display the linked content in a different window or frame, use the P:Telerik.Web.UI.RadTab.Target Targetproperty.
