Copy Appointment with Drag and Drop

[Friedhelm]

Can the end-user also copy an appointment in MultiDayView or WeekDayView of the RadScheduler control by using the drag and drop function and pressing the "Ctrl-Key" ?
a) from one Day to another day
b) from von Time to another time at the same day

Oh sorry, I see it's the wrong section here...please move it to RadScheduler

Best Regards

Hi Friedhelm,

Thank you for writing.

You can achieve the desired behavior in the AppointmentDropping event handler. Here is what you need to do:
1. Cancel the drop operation - this will prevent the dragged appointment from moving.
2. Creating the new Appointment and assign the desired properties from the dragged one (available in the event arguments).
3. Set the new appointment start, by taking it from the NewDate property of the event arguments.

Here is an example:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        DateTime start = new DateTime(2012, 08,16,10,0,0,0);
        radScheduler1.Appointments.Add(new Appointment(start, start.AddHours(1), "Hello", "description", "USA"));
        radScheduler1.AppointmentDropping += new EventHandler<AppointmentMovingEventArgs>(radScheduler1_AppointmentDropping);
    }

    void radScheduler1_AppointmentDropping(object sender, AppointmentMovingEventArgs e)
    {
        if (ModifierKeys == Keys.Control)
        {
            e.Cancel = true;

            Appointment newApp = new Appointment();
            newApp.Summary = e.Appointment.Summary;
            newApp.Description = e.Appointment.Description;
            newApp.Location = e.Appointment.Location;
            newApp.Start = e.NewDate;
            newApp.Duration = e.Appointment.Duration;
            //add any properties that you need
            radScheduler1.Appointments.Add(newApp);

        }
    }
}

I hope this helps.

Hi Stefan,
thank you for the answer.

But how can the end-user decide if he want copy or move the appointment, the windows standard solution is "press the Ctrl-Key while draging" or not.
What's the solution in RadScheduler?

Hello,

Thank you for writing back.

This is exactly what the provided code does - copy when Ctrl key is pressed and move when it is not. The check for the control key is the first line of code in the event handler:

if (ModifierKeys == Keys.Control)

Can you please give this approach a try and let me know whether it works for you?
 
All the best,

Hi Stefan, sorry I was to fast with reading your answer.
Now I've tried it.

1. It is running using the WeekView - but it's not running using the MultiDayView. Here the radScheduler_AppointmentDropping() method is not called.
   So I can move an appointment but not copy it.
2. How can I implement "user feedback" by showing the '+'-sign for the copy operation, usualy I do this by modifying the DragDropEffect.
   How does this work with RadScheduler?

Best regards
Friedhelm

Hi Friedhelm,

Thank you for writing.

We are aware of the limitation where the radScheduler_AppointmentDropping is not fired in MultiDayView. This functionality is missing and we are currently working on implementing it. In fact we are working on reworking the whole drag and drop functionality of the control in order to make it easily customizable, extendable and easy to use. Hopefully, it will make it for Q3 2012.

In regards to the plus sign, since this functionality is internally used and the resizing depends on it, we have to turn off the resizing during the dragging process. The whole approach is implemented in the attached project.

I hope this helps.

"Hopefully, it will make it for Q3 2012."

Did it make it?

Yes it did Thomas. Feel free to take advantage of it.
