How to do a DragAndDrop of ListView items into SfSchedule Control?
Schedule provides a support for drag-drop of items from ListView. This section briefly explains you about this support by creating an application to represent, drag-drop functionality in Schedule control from the ListView. You can store your appointments in ScheduleAppointmentCollection. GridView contains items that display the appointments with its Subject and Notes properties. You can drag and drop ListViewItem into corresponding schedule area. As of now the list view items must be of ScheduleAppointment type in order to drop the item in SfSchedule control.

EndTime = DateTime.Now.Date.AddHours(4),
AppointmentBackground = new SolidColorBrush(Colors.Green),
Subject = "Business Meeting",
Notes = "Consulting firm laws with business advisers"
});
app.Add(new ScheduleAppointment()
{
StartTime = DateTime.Now.Date.AddDays(1).AddHours(6),
EndTime = DateTime.Now.Date.AddDays(1).AddHours(8),
AppointmentBackground = new SolidColorBrush(Colors.Orange),
Subject = "Conference",
Notes = "Attend 2nd international conference about WinRT Development"
});
app.Add(new ScheduleAppointment()
{
StartTime = DateTime.Now.Date.AddDays(-2).AddHours(4),
EndTime = DateTime.Now.Date.AddDays(-2).AddHours(6),
AppointmentBackground = new SolidColorBrush(Colors.LightPink),
Subject = "Medical check up",

});
return app;
}

While Dragging, you can use DragItemsStarting event of GridView, to set the ScheduleAppointment by adding the dragged item in e.Data.Properties. The following code example explains you how to perform dragging event.
C#
private void gridview_DragItemsStarting(object sender, DragItemsStartingEventArgs e)
{
ScheduleAppointment app = ((ScheduleAppointment)e.Items[0]);
e.Data.Properties.Add("App", app);
this.selectedapp = app;
}
Drop appointments
