ASPxClientTab.SetEnabled(value) Method
Specifies whether the tab is enabled.
Declaration
SetEnabled(
value: boolean
): voidParameters
| Name | Type | Description |
|---|---|---|
| value | boolean |
|
Remarks
Use the SetEnabled method on the client to dynamically change a tab’s ability to respond to end-user interactions (such as mouse hovering or clicks). The tab’s initial availability state can be defined by using the TabBase.ClientEnabled property.
Note
The SetEnabled method is not in effect if a tab is initially disabled on the server by setting the TabBase.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.
