ASPxClientTab.SetVisible(value) Method

Specifies whether the tab is visible.

Declaration

SetVisible(
    value: boolean
): void

Parameters

Name Type Description
value boolean

true is the tab is visible; otherwise, false.

Remarks

Use the SetVisible method to dynamically define a tab’s visible state on the client. The original item’s visibility can be defined by using the TabBase.ClientVisible property.

Note

If a tab’s server TabBase.Visible property is set to false, this tab is not rendered into the web page at all, so it can’t be manipulated on the client side.

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.
