Assembly: DevExpress.Web.v24.1.dll
NuGet Package: DevExpress.Web
Declaration
Property Value
Type | Default | Description |
---|---|---|
ITemplate | null | An object supporting the ITemplate interface which contains the template used for displaying the text content of all root menu items within a menu. |
Remarks
Use the RootItemTextTemplate property to define the common content for all root menu items within a menu control. The template created using this property replaces the text content of each root menu item - in particular, the item’s text specified.
Note that any style settings defined for the root menu items via specific properties (such as the ASPxMenuBase.ItemStyle) are still in effect for the root menu items whose contents are specified, using the RootItemTextTemplate property.
The text content of an individual menu item can be defined using the item’s MenuItem.TextTemplate property. A text template for submenu items can be specified via the ASPxMenuBase.ItemTextTemplate property.
Note
Once a template defined via the RootItemTextTemplate property is created within a menu, it is instantiated within a container object of the MenuItemTemplateContainer type. This container object exposes a set of specific properties to which the template’s child controls can be bound.
Note
An RootItemTextTemplate cannot contain another menu control.
Example
This part of the Tabbed Menu demo illustrates how to customize the ASPxMenu control as a hierachical menu (with popped out submenus) which looks like a set of tabs.
Gradient borders for the menu’s root items (tabs) are drawn by using the RootItemTextTemplate property. The control’s style settings are defined via the ASPxMenuBase.ItemStyle property, ASPxMenuBase.SubMenuStyle property,etc.
