RadTabStrip provides a flexible client-side API - you can easily interact with the tabstrip in the browser using the tabstrip client-side object.

1. Getting the RadTabStrip client-side object:

RadTabStrip creates a client-side object with the ClientID of the tabstrip. You can obtain the reference using the following javascript code:

var tabStrip = <%= RadTabStrip1.ClientID %>;

2. Once you get the client-side object of RadTabStrip, you can use the FindTabByText / FindTabByValue methods to get the instance of a particular tab. Alternatively, you can use the SelectedTab property to get the instance of the currently selected tab. Example:

var tabStrip = <%= RadTabStrip1.ClientID %>;

var tabNewYork = tabStrip.FindTabByText("New York");

var selectedTab = tabStrip.SelectedTab;

3. When you get the instance of a particular tab, you can call the Disable() / Enable() / Select() methods:

var tabStrip = <%= RadTabStrip1.ClientID %>;

var tabNewYork = tabStrip.FindTabByText("New York");

tabNewYork.Disable();

tabNewYork.Enable();

tabNewYork.Select();
