Events Overview

RadToolTip and RadToolTipManager both support the same client-side events that let you customize the behavior of the control:

To use these events, simply write a JavaScript function that can be called when the event occurs. Then assign the name of the JavaScript function as the value of the the corresponding property.

<script type="text/javascript">
    function clientShow(sender, eventArgs)
    {
        alert("OnClientShow tool tip: " + sender.get_text());
    } 
</script>
<telerik:RadToolTip RenderMode="Lightweight" ID="RadToolTip1" runat="server" Skin="Inox" TargetControlID="Button1"
    IsClientID="true" OnClientShow="clientShow" Text="text">
</telerik:RadToolTip>

You can also assign event handlers in client-side code. For more information see the Setting Event Handlers via JavaScript article.

For a live example illustrating the RadToolTip client-side events, see the Client-side events live demo.
