The OnClientMouseOver client-side event occurs when the mouse moves over an item in the toolbar.

The event handler receives two parameters:

  1. The instance of the toolbar firing the event.

  2. An eventArgs parameter containing the following methods:

  • get_item returns a reference to the item under the mouse.

  • get_domEvent returns the DOM event object for the mouse movement.

You can use this event to respond when the mouse is over an item:

<script type="text/javascript">
    function ShowItem(toolbar, args) 
        var label = document.getElementById("Label1");
        label.innerText = args.get_item().get_text();

<telerik:RadToolBar id="RadToolBar1" runat="server"
        <telerik:RadToolBarButton Text="Button1" />     
        <telerik:RadToolBarButton Text="Button2" />    
        <telerik:RadToolBarButton Text="Button3" /> 
<br />
<br />
<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
