ASPxClientNavBarItem.SetEnabled(value) Method

Specifies whether the item is enabled.

Declaration

SetEnabled(
    value: boolean
): void

Parameters

Name Type Description
value boolean

true if the item is enabled; otherwise, false.

Remarks

Use the SetEnabled method on the client to dynamically change an item’s ability to respond to end-user interactions (such as mouse hovering or clicks). The item’s initial availability state can be defined by using the NavBarItem.ClientEnabled property.

Note

The SetEnabled method is not in effect if a navbar item is initially disabled on the server by setting the NavBarItem.Enabled property to false.

Example

This example demonstrates how specific item characteristics (the text, visibility, availability to end-users, checked state) of a control (the ASPxMenu in this case) can be changed on the client side using available JavaScript methods.
