Hi,

There are several ways that you can do this:

1.You can customize the resize behavior by implementing custom DragDropBehavior class and override the Resize method as it is described in our documentation. In this method you can display dialog and modify the resized appointment.

2.Use AppointmentEditing/AppointmentEdited events and execute your code there. In this case you will still need to override the Resize method in order to recognize whether the appointment is edited by resize.
For example:
operation can be easy. Here is sample code:

public class CustomDragDropBehavior : ScheduleViewDragDropBehavior
{
    public ScopeFlag IsResizing { get; set; }

    public CustomDragDropBehavior()
    {
        this.IsResizing = new SingleScopeFlag();
    }



    public override void Resize(DragDropState state)
    {
        using (this.IsResizing.BeginScope())
        {
            base.Resize(state);
        }
    }
}

private void OnRadScheduleViewAppointmentEdited(object sender, Telerik.Windows.Controls.AppointmentEditedEventArgs e)
{
    var scheduleView = (RadScheduleView)sender;
    var customDragDropBehavior = (CustomDragDropBehavior)sv.DragDropBehavior;
    if (customDragDropBehavior.IsResizing.IsActive)
    {
        RadWindow.Alert("Changed by drag-drop/resize");
    }
}

In this example a class from Telerik's assemblies was use for the flag - SingleScopeFlag. However you can always use a simple boolean flag that is true while the drag or resize operation is happening.

3.You can customize the dialog that is displayed by design when an occurrence of recurring appointment is edited and then again use the AppointmentEdited to save the changes.
