ASPxMenuBase.EnableClientSideAPI Property

Gets or sets a value that specifies whether the menu can be manipulated on the client side via code.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v19.2.dll

Declaration

C#

[DefaultValue(false)]
public bool EnableClientSideAPI { get; set; }

VB.NET

<DefaultValue(False)>
Public Property EnableClientSideAPI As Boolean

Property Value

Type	Default	Description
Boolean	**false**	true if the menu’s client object model is fully available; false if no programmatic interface is available for the menu on the client side.

Remarks

The EnableClientSideAPI property controls the availability of the client-side API for the control.

A menu control implements a comprehensive JavaScript-written client-side object model (client API), allowing you to programmatically manipulate the control on the client.

If you want to use the control’s client-side API in your application, set the EnableClientSideAPI property to true, to make sure that the client API is available on the client side.

Note

Regardless of the EnableClientSideAPI property setting, the client-side API is automatically enabled if the ASPxMenuBase.ClientInstanceName property is defined, or any client event exposed by the ASPxMenuBase.ClientSideEvents property is handled.

Example

This part of the Templates demo illustrates how to use template technology within the ASPxMenu control.

A specific MenuItem.SubMenuTemplate property is used to define the template for the first root menu item’s submenu. The content of a SubMenuTemplate type is represented by the ASPxSiteMapControl, which displays a hierarchical structure of links (site map nodes) that reference different web pages within the site.

The appearance of the second root menu item’s sub-item is defined via the MenuItem.Template property of each sub-item.
