Drag drop appointment and open dialog after drop

[Karl]

Hi,

I've been following this example which works great
:
http://www.telerik.com/help/winforms/scheduler-appointments-and-dialogs-drag-and-drop-from-another-control.html

What I would like to do is once I have dropped the appointment I would like the apppointment dialog box to open so I can enter some addtional data. I am also using the CustomEditAppointmentDialog example so I can use my own fields etc.

Is this possible, I've tried firing the _AppointmentEditDialogShowing event but can't pas the appointment details ie times etc it comes up with a invalid cast.

Thanks

Hi Karl,

Thank you for your question.

Yes, you can achieve this by calling the ShowAppointmentEditDialog of RadScheduler after you have added the appointment to the Appointments collection. The following code snippet demonstrates how you should modify the radScheduler1_DragDrop method of the mentioned help article in order to achieve the desired behavior:

private void radScheduler1_DragDrop(object sender, DragEventArgs e)
{
    Point point = this.radScheduler1.PointToClient(new Point(e.X, e.Y));

    DayViewAppointmentsTable table = (this.radScheduler1.SchedulerElement.ViewElement as SchedulerDayViewElement).DataAreaElement.Table;
    SchedulerCellElement schedulerCell = SchedulerUIHelper.GetCellAtPoint(point, table.Children);
    if (schedulerCell != null)
    {
        DragObject dragObject = e.Data.GetData(typeof(DragObject)) as DragObject;
        if (dragObject != null)
        {
            this.radScheduler1.Appointments.BeginUpdate();
            Appointment appointment = CreateAppointment(schedulerCell.Date, dragObject);
            this.radScheduler1.Appointments.Add(appointment);
            this.radScheduler1.Appointments.EndUpdate();

            this.radScheduler1.ShowAppointmentEditDialog(appointment, false);
        }
    }

    this.mouseDownPosition = Point.Empty;
    this.isDragging = false;
}

I hope you find this useful. Do let me know if you have any additional questions.

Hi,

Thanks for the reply, this works to open the dialog but still doesn't allow me to access my custom fields.

This would work if I doubled click to add an appointment.

Would I need to do anything else?

Thanks

Hello Karl,

The reason might be that you are instantiating the default Appointment type on the DragDrop event where you should instantiate your custom appointment type instead. However, I am not sure if this is the case, because I do not have the source code of your project. Therefore I have prepared a small sample project which implements the desired scenario. I hope you find it useful.

If you have any further questions, I will be glad to answer them.
