ModifiedAppointment Values

[Michael J.]

Im working with the RAD Scheduler control.  I've declared a RAD Scheduler control on my ASPX page, and it's OnAppointmentUpdate attribute is as follows:

OnAppointmentUpdate="RadScheduler1_AppointmentUpdate"

In the code-behind, the event handler is defined as follows:

protected void RadScheduler1_AppointmentUpdate(object sender, AppointmentUpdateEventArgs e)
{
    //CODE
}

Documentation says that by referencing e.ModifiedAppointment, I should be able to access the new Appointment values I've entered right before they're inserted into the database.

But -- These values are the same as the original Appointment object!  It appears as though any new values are not accessible via the e.ModifiedAppointment object.

Any ideas what's going on?  Seems easy, but I'm stumped!

TIA!
Mike

Anyone?

Hello Michael J.,

This is strange issue, does the following code returns the same values after a modify to an appointment?

 protected void RadScheduler1_AppointmentUpdate(object sender, AppointmentUpdateEventArgs e)
    {
        string originalAppointment = e.Appointment.Subject;
        string modifiedAppointment = e.ModifiedAppointment.Subject;
    }

Genady,

When the following event handler is invoked:

protected void RadScheduler1_AppointmentUpdate(object sender, AppointmentUpdateEventArgs e)

{

string originalAppointment = e.Appointment.Subject;

string modifiedAppointment = e.ModifiedAppointment.Subject;

}

...the values of originalAppointment and modifiedAppointment are the same.

The application is smart enough to understand on the server side that an update is taking place.  However, the argument values containted in "e" are not updated with the latest changes from the screen. 

Any ideas?

Thanks,
Mike

Problem solved, although it doesn't make much sense to me up front.

I configured a new RAD Scheduler object on my ASPX page and set it's attributes appropriately.  Although the attributes are the same as those in my prior RAD Scheduler, the AppointmentUpdate's e.ModifiedAppointment object is now being passed the correct updated Appointment values from the screen.

Hope this helps,

Mike

Genady,

I am having this same issue and the solution below was unfortunately not a helpful answer.  I have spent so many hours on this I have lost count. 

When dragging and dropping an appointment, the AppointmentUpdate Server event has the same value for the event args for the e.Appointment AND e.ModifiedAppointment.  When I add the client event OnClientAppointmentMoveEnd, I get the correct modified value on the client side, but the serverside is always wrong.

Thanks for the help,

Ryan (Code Below)

Server Code: (values for e.Appointment and e.ModifiedAppointment are the same)

protected void CalendarRadScheduler_AppointmentUpdate(object sender, AppointmentUpdateEventArgs e)
        {
            if (e.Appointment.Start != e.ModifiedAppointment.Start)
            {
                Appointment objModApt = e.ModifiedAppointment;

                //load message from database
                MessageDAO daoMessage = new MessageDAO();
                MessageDTO dtoMessage = daoMessage.GetById((int)objModApt.ID);

                //update message with new time
                dtoMessage.Start = objModApt.Start;
                dtoMessage.End = objModApt.Start.AddMinutes(10);

                //Save updated message to database
                dtoMessage.Method = CoreToolkit.ObjectMethod.Modify;
                daoMessage.Save(dtoMessage);
            }
            else
            {
                e.Cancel = true;
            }
        }

Hello rjb227s,

As we have replied in the other support thread, we need a sample project in order to provide you with a solution for this problem. Could you please open a support ticket and attach a sample there.

All the best,

Ever get this resolved?  I have a similar issue related to Attributes.
In the AppointmentUpdate handler the attribute count is different.


int t1 = e.Appointment.Attributes.Count;
int t4 = e.ModifiedAppointment.Attributes.Count;

I'm fighting another problem where I renamed a CustomAttribute and now I don't see it.

[Plamen]

Hi Jon,

 
This unusual behavior is most probably caused by the way to bind you RadScheduler because we are not aware of such known bug with the custom attributes.
