OnClientToggleStateChanged | RadToggleButton for ASP.NET AJAX Documentation
Edit this page


The toggleStateChanged event is subsequent to the toggleStateChanging event, and occurs when the RadToggleButton state is changed.

The event handler receives two parameters:

  1. The instance of the clicked RadToggleButton control.

  2. An eventArgs parameter of type Telerik.Web.UI.RadButtonCheckedEventArgs, containing the following properties and methods:

    • get_currentToggleState() - returns the current RadButtonToggleState object applied to the button.

    • get_commandName() - returns the value assigned to the RadToggleButton's CommandName property.

    • get_commandArgument() - returns the value assigned to the RadToggleButton's CommandArgument property.

This event is useful when the user wants to execute custom client code when the button changes its toggle state.

Example 1: Using the OnClientToggleStateChanged event to get the text of the currently selected state.

<script type="text/javascript">
    function toggleStateChanged(sender, args) {

<telerik:RadToggleButton ID="RadToggleButton1" runat="server"
    AutoPostBack="false" OnClientToggleStateChanged="toggleStateChanged">
        <telerik:ButtonToggleState Text="State 1" />
        <telerik:ButtonToggleState Text="State 2" />
