Hi,

From my main form (where scheduler is), I am trying to add new appointment and show edit form like this:

IEvent newAppointment = new CustomAppointment();

newAppointment.Start = Record.RecordStart;

newAppointment.End = DateTime.Now;

// ...

cScheduler.Appointments.Add(newAppointment);

cScheduler.ShowAppointmentEditDialog(newAppointment, false);

The problem is when user click cancel or close button in edit form. After that appointment will be still in collection.
How to check if user cancel appointment and delete it form collection?

RadTreeView winforms - DataBinding and Images

I am using a BindingList object as my datasource and I would like to use an image list to display images in my treeview. I looked for an ItemDataBound event or something similiar, but I did not see it. I tried to use the DrawNode Event but I would get an error saying that the ImageIndex Property could not be updated because the treeview was in lock mode or something along those lines. How do you suggest adding images when databinding?

Thanks.

Filter / Refresh Appointments

My project contains several parameters that can be used to filter the displayed appointments.
Examples are:
1. Guest Name
2. Employee Name
3. Appointment Category (Spa, Sports, etc.)
4. Location (Spa room 1, Tennis Court 1, Stable 1, etc.)
5. Appointment Type (massage, tennis, horse back riding, etc.)

I would like to provide a combobox for each parameter and allow the user to select the filters. Is there a method, similar to filtering a bindingsource?

Also, Is there any method to refresh the appointments? If computer 1 is displaying the scheduler and a new appointment is made at computer 2, I would like computer 1 to be able to click a "refresh" button and see the changes to the database.
