Remarks

By default, an inplace editor (of the text type) can be used by end-users to either create a new appointment (an inplace editor is activated after an end-user selects a time slot and starts typing in it) or edit an existing appointment’s subject (an inplace editor is activated by either a single click on the selected appointment or pressing the F2 key when it’s selected). Use the AllowInplaceEditor property to control the availability of such functionality to end-users with respect to an appointment’s type.

Note

If the AllowInplaceEditor property is set to UsedAppointmentType.Custom, then whether an inplace editor can be activated for an appointment or not is decided in the SchedulerControl.AllowInplaceEditor event handler.

Example

This example demonstrates how to implement custom rules for editing and deleting appointments. The code below allows an appointment to be edited only by its owner (the end-user who created it). To do this it’s necessary to set the SchedulerOptionsCustomization.AllowAppointmentEdit and SchedulerOptionsCustomization.AllowAppointmentDelete properties to UsedAppointmentType.Custom, and handle the SchedulerControl.AllowAppointmentEdit and SchedulerControl.AllowAppointmentDelete events to implement custom logic for editing appointments.

C#

using DevExpress.XtraScheduler;
// ...

private void schedulerControl1_AllowAppointmentDelete(object sender, 
    AppointmentOperationEventArgs e) {
   // Allow only the user who created this appontment to delete it.
   e.Allow = CanUserModifyThisAppointment(e.Appointment);
}
private void schedulerControl1_AllowAppointmentEdit(object sender, 
    AppointmentOperationEventArgs e) {
   // Allow only the user who created this appontment to modify it.
   e.Allow = CanUserModifyThisAppointment(e.Appointment);
}
// Determine if the current user is the same 
// as the one who created the specified appointment 
bool CanUserModifyThisAppointment(Appointment apt) {
   object obj = apt.CustomFields["Owner"];
   if (obj == null)
      return true;
   string appointmentOwner = obj.ToString();
   if (appointmentOwner == String.Empty)
      return true;
   return (String.Compare(appointmentOwner, tbUserName.Text, true) == 0);
}

VB.NET

Imports DevExpress.XtraScheduler
' ...

Private Sub schedulerControl1_AllowAppointmentDelete(ByVal sender As Object, _
ByVal e As AppointmentOperationEventArgs)
   ' Allow only the user who created this appontment to delete it.
   e.Allow = CanUserModifyThisAppointment(e.Appointment)
End Sub
Private Sub schedulerControl1_AllowAppointmentEdit(ByVal sender As Object, _
ByVal e As AppointmentOperationEventArgs)
   ' Allow only the user who created this appontment to modify it.
   e.Allow = CanUserModifyThisAppointment(e.Appointment)
End Sub
' Determine if the current user is the same 
' as the one who created the specified appointment 
Private Function CanUserModifyThisAppointment(ByVal apt As Appointment) As Boolean
   Dim obj As Object = apt.CustomFields("Owner")
   If obj Is Nothing Then
      Return True
   End If
   Dim appointmentOwner As String = obj.ToString()
   If appointmentOwner = String.Empty Then
      Return True
   End If
   Return (String.Compare(appointmentOwner, tbUserName.Text, True) = 0)
End Function
