Appointment Dragging and Resizing Enhancements

All the WinSchedule™ controls expose four completely new events for appointments dragging and resizing actions: AppointmentsDragging , AppointmentsDragDrop , AppointmentResizing , and AppointmentResized .

The “ing” events are cancelable, and their event arguments classes expose a property which defines which phase of the drag/resize operation the firing represents, i.e., whether it is beginning (first drag after MouseDown), in progress (MouseMove), or ending (MouseUp). Cancellation during any of these phases is fully supported, which results in the appointment times/owner reverting to their pre-drag states. The event arguments classes also expose a read-only collection of appointments which contain references to the actual instances which reside in the Appointments collection. Dragging Appointments from one Owner to another can also be prevented.

In Visual Basic:

AddHandler Me.ultraDayView1.AppointmentsDragging, AddressOf ultraDayView1_AppointmentsDragging
AddHandler Me.ultraDayView1.AppointmentResized, AddressOf ultraDayView1_AppointmentResized
Private Sub ultraDayView1_AppointmentsDragging(ByVal sender As Object, ByVal e As AppointmentsDraggingEventArgs) Handles ultraDayView1.AppointmentsDragging
    Dim control As ControlWithActivityBase = TryCast(sender, ControlWithActivityBase)
    'Get WinSchedule control name
    System.Console.WriteLine(control.Name.ToString())
    System.Console.WriteLine(e.Phase.ToString())
    System.Console.WriteLine(e.InitialOwner.ToString())
    'Date Time of the appointment
    System.Console.WriteLine(e.InitialDateTime.ToString())
    'New Date Time to which the appointment has moved
    System.Console.WriteLine(e.NewDateTime.ToString())
    'Prevent dragging appointment from one Owner to another
    e.AllowOwnerChange = False
End Sub
Private Sub ultraDayView1_AppointmentResized(ByVal sender As Object, ByVal e As AppointmentResizedEventArgs) Handles ultraDayView1.AppointmentResized
    'Specifies whether starting Date Time or Ending Date Time was resized
    System.Console.WriteLine(e.ResizeType.ToString())
End Sub

In C#:

this.ultraDayView1.AppointmentsDragging += new AppointmentsDraggingHandler(ultraDayView1_AppointmentsDragging);
this.ultraDayView1.AppointmentResized += new AppointmentResizedHandler(ultraDayView1_AppointmentResized);
void ultraDayView1_AppointmentsDragging(object sender, AppointmentsDraggingEventArgs e)
                {
                  ControlWithActivityBase control = sender as ControlWithActivityBase;
                    //Get WinSchedule control name
                    System.Console.WriteLine(control.Name.ToString());
                    System.Console.WriteLine(e.Phase.ToString());
                    System.Console.WriteLine(e.InitialOwner.ToString());
                   //Date Time of the appointment
                    System.Console.WriteLine(e.InitialDateTime.ToString());
                   //New Date Time to which the appointment has moved
                    System.Console.WriteLine(e.NewDateTime.ToString());
                   //Prevent dragging appointment from one Owner to another
                    e.AllowOwnerChange = false;
                }
   void ultraDayView1_AppointmentResized(object sender, AppointmentResizedEventArgs e)
                {
                    //Specifies whether starting Date Time or Ending Date Time was resized
                    System.Console.WriteLine(e.ResizeType.ToString());
                }
