Disable edit dialogue based on appointment category

[Sergey]

Is it possible to prevent edit appointment dialogue from opening when the user double clicks on appointment of specific category?

[Sergey]

I'm using AppointmentEditingEvent and set e.Cancel = true, but the dialogue still pops up.

Hello Sergey,

To disable dialogs from showing you need to handle the ShowDialog event in RadScheduleView.

This article describes how to disable all edit dialogs. Is it possible to disable edit dialogs only for jobs of specific category?

Hello Sergey,

In the ShowDialog event of the RadScheduleView the passed ShowDialogEventArgs e contains all of the appointment class information, you can use that argument to filter the wanted appointment category and set a true value to the Cancel property of that appointment.

I can't find any of the appointment class information in ShowDialogEventArgs e. Can you tell me which property I should be looking at?

[Vladi]

Hello Sergey,

In the ShowDialog event the passed ShowDialogEventArgs argument contains the property DialogViewModel that could be cast to AppointmentDialogViewModel. That viewModel contains all of the appointment class information which can be used to filter the appointment's category.

Thanks!

Sorry, I still cannot find the appointment category.

AppointmentDialogViewModel has only property Categories, which contains a list of two categories, none of which is correct one. 

It does work, for example, in the AppointmentEditing event, where AppointmentEditingEventArgs argument contains the property Appointment, which has the property Category which always contains correct appointment category no matter which appointment I double click.

[Sergey]

Anyone have any ideas? Should I submit a ticket?

Hi Sergey,

Here is sample code representing the ShowDialog event handler that cancels the ShowDialog for appointments with Blue Category:

private void RadScheduleView_ShowDialog(object sender, Telerik.Windows.Controls.ShowDialogEventArgs e)
{
    var viewModel = e.DialogViewModel as AppointmentDialogViewModel;
    var currentAppointment = viewModel.Occurrence.Appointment as Task;

    if ((currentAppointment.Category != null) && (currentAppointment.Category.CategoryName == "Blue Category"))
    {
        e.Cancel = true;
    }
}

Hope this helps.

Kind regards,

Aha, so it was Occurrence property! Thanks!

You could also add "e.Handled = true" to your original attempt, Sergey, and it also shouldn't open up the dialog (it works in my case).
