We have fixed the issue described in this ticket and will include the fix in our next maintenance update. To apply this solution before the official update, request a hotfix by clicking the corresponding link for product versions you require.

Note: Hotfixes may be unavailable for beta versions and updates that are about to be released.

Additional information:

We've introduced the following APIs that allow you to directly track the AppointmentEditDialogViewModel's save, load and validation state.
- TrackLoad method
- TrackSave method
- TrackValidation method
The new DialogViewModelBase.DialogTitle property allows you to specify a dialog's title text.

C#
var viewModel = ASPxScheduler1.OptionsForms.DialogLayoutSettings.AppointmentDialog.ViewModel; viewModel.TrackLoad((controller) => { viewModel.DialogTitle = controller.IsNewAppointment ? "Create New Appointment" : "Edit Appointment: " + controller.Subject; }); viewModel.TrackValidation(() => { if(string.IsNullOrEmpty(viewModel.Subject) || viewModel.Subject.Length < 3) { viewModel.IsValid = false; viewModel.ErrorMessage = "Subject should be at least 3 characters"; } });
