I am doing the following to load my own custom appointment dialog, it sort of works, as in it loads my view but I was wondering if there is a cleaner approach. I also need the appointment dialog to be modal and there does not seem to be a way of doing this.

public

class CustomScheduleDialogFactory : ScheduleDialogFactoryBase

    {

public override ActivityTypes SupportedActivityDialogTypes        {   

get { return ActivityTypes.Appointment; }

        }

public override FrameworkElement CreateActivityDialog(

FrameworkElement container,       

XamScheduleDataManager dataManager,

ActivityBase activity,        

bool allowModifications,

bool allowRemove)

        {           

switch (activity.ActivityType)

            {

case ActivityType.Appointment:

                    {                

AppointmentDialogView view = new AppointmentDialogView(activity as Appointment, null);

                    return view;

                    }

default:              {                       

return null;

                    }

            }

        }

    }
