# OnClientAppointmentDoubleClick

The **OnClientAppointmentDoubleClick** client-side event is called when the user double-clicks on an appointment.

Two parameters are passed to the event handler:

* **sender** is the scheduler client object.

* **eventArgs** has one method - **get_appointment()** that returns the appointment instance.

## Example

```ASP.NET
<script type="text/javascript">   
function OnClientAppointmentDoubleClick(sender, eventArgs)
{
	var apt = eventArgs.get_appointment();
	alert("You double-clicked on an appointment with the subject: " + apt.get_subject());
}
</script>
<telerik:RadScheduler
 ID="RadScheduler1"
 runat="server"  
 OnClientAppointmentDoubleClick="OnClientAppointmentDoubleClick"
 DataSourceID="AppointmentsDS" />
	
```
