RadScheduler with multiple resources

Create a custom EditAppointmentDialog which allows assigning multiple resources to a single appointment.

The data engine of RadScheduler allows the user to have appointments and resources in many-to-many relation. However, you cannot create such relations using the standard EditAppointmentDialog because the resources combo box does not allow multi selection.

In order to get the desired functionality, you should create a custom EditAppointmentDialog, hide the resources combo box and add a RadListControl which allows multiple selection. Then you should override the logic for loading and saving the users’ settings.
