Telerik RadScheduler cancel appointment move after Server-Side validation error
<p>I am using Telerik RadScheduler with Web Service binding.</p>

<p>When I drag an appointment to another timeslot, I do some client-side validation in <code>OnClientAppointmentMoveEnd</code>, and if that succeeds I set <code>args.set_cancel(true);</code></p>

<p>It then hits my web service method <code>UpdateAppointment</code>.  </p>

<p>My server side code within this web service call then does some additional validation based on a database query.  </p>

<p>My question is - if this server side validation fails, how can I get the client-side appointment to move back to where it originated?  I can catch a status or message in <code>OnClientRequestFailed</code> but is there a way to cancel the move event after the web service call, or move the appointment back?</p>
