PostBack on Double Click?

I see that there's a way to implement a post back on a row click. (by setting ClentSettings -> EnablePostBackOnRowClick to true).

Is there a way to do the same thing with only a double click? (Ie. I don't want a post back on a single click, only a double click)

Webservice Validation before editing appointment

Hi,

I have been trying to call a webservice validation to the events before the editor allows someone to edit an appointment.

But i can't find a way to actually stop the scheduler from opening the form.

I call the validation OnClientAppointmentDoubleClick

    
            var hasReservations = null; 
        
            function OnClientAppointmentDoubleClick(sender, eventArgs) 
        
            { 
        
                var strId = eventArgs.get_appointment().get_id().substring(0, 36); 
        
                WebServices.SiteService.EventHasRegistration(strId, OnLookupComplete, OnError);

then i set the hasReservations = true/false depending if there are any reservations to that appointment.

I try using the following code to stop the schduler, but it wont work due to the async. delay.

    
            if(hasReservations == null || hasReservations== 'undefined') 
        
            { 
        
                eventArgs.set_cancel(true); 
        
                radalert("Validation service currently unavailable. Editing events are not available at this time."); 
        
                return; 
        
            } 
        
            if(hasReservations) 
        
            { 
        
                radalert("Some occurrences of this series have reservations assigned to them, they will not be modified."); 
        
                eventArgs.set_cancel(true); 
        
            }

How am i able to implement such thing?

This doesn't have to happen on the client side, but i cant't find a way to validate it before the client recurrence popup is displayed.

The client documentation for the scheduler is horrible, and i cant find anything i need.

Someone please help me!

Thanks

Fabio
