Telerik.Web.UI.RadPanelItem

This partial Class defines RadPanelItem object that inherits NavigationItem, IRadPanelItemContainer and ICloneable.

Remarks

The Telerik.Web.UI.RadPanelBar RadPanelBarcontrol is made up of items. Items which are immediate children of the panelbar are root items. Items which are children of root items are child items. A item usually stores data in two properties, the P:Telerik.Web.UI.RadPanelItem.Text Textproperty and the P:Telerik.Web.UI.RadPanelItem.Value Valueproperty. The value of the P:Telerik.Web.UI.RadPanelItem.Text Textproperty is displayed in the RadPanelBarcontrol, and the P:Telerik.Web.UI.RadPanelItem.Value Valueproperty is used to store additional data. To create panel items, use one of the following methods:bullet Use declarative syntax to define items inline in your page or user control. Use one of the constructors to dynamically create new instances of the Telerik.Web.UI.RadPanelItem RadPanelItemclass. These items can then be added to the Itemscollection of another item or panelbar. Data bind the RadPanelBarcontrol to a data source. When the user clicks a panel item, the RadPanelBarcontrol can navigate to a linked Web page, post back to the server or select that item. If the P:Telerik.Web.UI.RadPanelItem.NavigateUrl NavigateUrlproperty of a item is set, the RadPanelBarcontrol 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.RadPanelItem.Target Targetproperty.
