The OnClientMouseOut client-side event occurs when the mouse moves off a tab in the tab strip.

The event handler receives two parameters:

  1. The instance of the tab strip firing the event.

  2. An eventArgs parameter containing the following methods:

  • get_tab returns a reference to the RadTab that the mouse just left.

  • get_domEvent returns a reference to the DOM event object for the mouse movement.

You can use this event to respond when the mouse moves off a tab:

<script type="text/javascript">
function markTab(sender, args)
    var attributes = args.get_tab().get_attributes();
    attributes.setAttribute("visited", "true");
  ID="RadTabStrip1" runat="server" OnClientMouseOut="markTab">
  <telerik:RadTab runat="server" Text="Item 1" visited="false" />
  <telerik:RadTab runat="server" Text="Item 2" visited="false" />
  <telerik:RadTab runat="server" Text="Item 3" visited="false" />
