Hi Oliver,

 
You can handle the onClientAppointmentMoveStart and set the desired start and end time as it is set to 13-th of April in the code bellow:

function OnClientAppointmentMoveStart(sender, args) {
           var start = new Date(2012, 3, 13, 11, 33, 0);
           var oneHourLater = new Date(2012, 3, 13, 12, 33, 0);
           args.get_appointment().set_start(start);
           args.get_appointment().set_end(oneHourLater);
           sender.updateAppointment(args.get_appointment());
           args.set_cancel(true);
       }

Hope this will be helpful.

All the best,

I tried the above code with some variations but its not working. Here is my code. I know I am making a silly mistake.
function OnClientAppointmentMoveEnd(sender, eventArgs) {
        var apt = eventArgs.get_appointment();
        //alert(apt._start);
        var oldstart = apt._start;
        var oldend = apt._end;
        var newstart = eventArgs.get_newStartTime();
        //var newstart = eventArgs.get_newStartTime();
        eventArgs.get_appointment().set_start(newstart);
        eventArgs.get_appointment().set_end(oldend);
        sender.updateAppointment(eventArgs.get_appointment());
        eventArgs.set_cancel(true);
    }

Hello Vijaianand,

 I have inspected the code that you pasted. It seems that you are trying to change only the start of the dragged appointment and persist the "old End". This was working properly at my side in all case without those when the start time was set to be greater than the end time which is forbidden and is an expected error. Here is the code that I added in order to prevent the error:

function OnClientAppointmentMoveEnd(sender, eventArgs) {
  
    var apt = eventArgs.get_appointment();
    //alert(apt._start);
    var oldstart = apt._start;
    var oldend = apt._end;
    var newstart = eventArgs.get_newStartTime();
    //var newstart = eventArgs.get_newStartTime();
    eventArgs.get_appointment().set_start(newstart);
    if (newstart < oldend) {
        eventArgs.get_appointment().set_end(oldend);
        sender.updateAppointment(eventArgs.get_appointment());
        eventArgs.set_cancel(true);
    }
}

Here you can see a video of my test as well.

Hope this will be helpful.

I did use your code and still having same issue. The appointment is not moving to the new location and it just pop's back to the old location. If you see your video, it does the same sometimes. When you drag and drop, it just pops back down the original but sometimes it works fine in the video but not for me.

Hi Vijaianand,

 
This unusual behavior is most probably caused because you have not handled update event and this causes the appointments to reload instead of changing their start and end time.

I am attaching a sample project that shows how should you bind a RadScheduler to ObjectDataSource in order to have a working drag and drop functionality.

Hope this will be helpful.
 

Kind regards,
