Events Overview
RadToolTip and RadToolTipManager both support the same client-side events that let you customize the behavior of the control:
-
OnClientBeforeShow occurs just prior to the display of the tool tip.
-
OnClientShow occurs as the tooltip is displayed.
-
OnClientBeforeHide occurs just prior to the tool tip being hidden.
-
OnClientHide occurs as the tooltip is hidden.
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.
