Description
When you have a custom implementation for the Appointment class, e.g. you extended the Appointment class with an Email field and try to copy/paste it, only the content of the basic Appointment class are being transferred. A common requirement is to copy/paste the Email field as well.
Solution
In order to copy/paste a custom field (e.g. Email) in the Appointment, you can store the value of the selected object in the AppointmentCopying event and assign the stored value in the AppointmentAdded event. Here is demonstrated a sample approach:
private void radScheduler1_AppointmentsCopying(object sender, SchedulerClipboardEventArgs e)
{
this.radScheduler1.Tag = ((AppointmentWithEmail)e.Appointments[0]).Email;
}
private void radScheduler1_AppointmentAdded(object sender, AppointmentAddedEventArgs e)
{
if (this.radScheduler1.Tag + "" != "")
{
((AppointmentWithEmail)e.Appointment).Email = this.radScheduler1.Tag.ToString();
}
this.radScheduler1.Tag = null;
}
Private Sub radScheduler1_AppointmentsCopying(ByVal sender As Object, ByVal e As SchedulerClipboardEventArgs)
Me.RadScheduler1.Tag = (CType(e.Appointments(0), AppointmentWithEmail)).Email
End Sub
Private Sub radScheduler1_AppointmentAdded(ByVal sender As Object, ByVal e As AppointmentAddedEventArgs)
If Me.RadScheduler1.Tag & "" <> "" Then
Dim a As AppointmentWithEmail = TryCast(e.Appointment, AppointmentWithEmail)
a.Email = Me.RadScheduler1.Tag.ToString()
End If
Me.RadScheduler1.Tag = Nothing
End Sub
If you need to have full control on the copy/paste operations in RadScheduler, you can create a derivative of the SchedulerInputBehavior, override its HandleKeyDown method and execute the desired logic when the Control key is pressed in combination with Keys.V or Keys.C:
public class CustomSchedulerInputBehavior : SchedulerInputBehavior
{
public CustomSchedulerInputBehavior(RadScheduler scheduler) : base(scheduler)
{
}
public override bool HandleKeyDown(KeyEventArgs args)
{
if (args.Modifiers == Keys.Control)
{
switch (args.KeyCode)
{
case Keys.C:
this.Scheduler.Copy();
break;
case Keys.X:
this.Scheduler.Cut();
break;
case Keys.V:
this.Scheduler.Paste();
break;
}
}
return false;
}
}
Public Class CustomSchedulerInputBehavior
Inherits SchedulerInputBehavior
Public Sub New(ByVal scheduler As RadScheduler)
MyBase.New(scheduler)
End Sub
Public Overrides Function HandleKeyDown(ByVal args As KeyEventArgs) As Boolean
If args.Modifiers = Keys.Control Then
Select Case args.KeyCode
Case Keys.C
Me.Scheduler.Copy()
Case Keys.X
Me.Scheduler.Cut()
Case Keys.V
Me.Scheduler.Paste()
End Select
End If
Return False
End Function
End Class
Then, set the RadScheduler.SchedulerInputBehavior property to the custom behavior that you have:
this.radScheduler1.SchedulerInputBehavior = new CustomSchedulerInputBehavior(this.radScheduler1);
Me.RadScheduler1.SchedulerInputBehavior = New CustomSchedulerInputBehavior(Me.RadScheduler1)
