Disable the "dateStart" and "dateEnd" fields on the AppointmentEditForm

[Chad]

Hello, i was curious if there is any special way that i need to implement inorder to Disable (.enabled = false) the dateStart and dateEnd fields ont he edit form.  i want to disallow the user from editing these fields if the appointment is in the past and settings then everywhere i have tried so far is having no effect.  timeStart and timeEnd were successfully disabled using normal methods.

Hello Chad,

Thank you for contacting us.

You can disable these fields by overriding the behavior of the default dialog and replacing it in the  AppointmentEditDialogShowing event. Here is a code sample that demonstrates this:

public class EditDialogDisabledFields : EditAppointmentDialog
{
    protected override void OnShown(EventArgs e)
    {
        base.OnShown(e);

        if (Appointment.End < DateTime.Now)
        {
            this.dateStart.Enabled = false;
            this.timeStart.Enabled = false;
            this.dateEnd.Enabled = false;
            this.timeEnd.Enabled = false;
        }
        else
        {
            this.dateStart.Enabled = true;
            this.timeStart.Enabled = true;
            this.dateEnd.Enabled = true;
            this.timeEnd.Enabled = true;
        }
    }
}


public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        this.radScheduler1.AppointmentEditDialogShowing += new EventHandler<AppointmentEditDialogShowingEventArgs>(radScheduler1_AppointmentEditDialogShowing);
    }

    void radScheduler1_AppointmentEditDialogShowing(object sender, AppointmentEditDialogShowingEventArgs e)
    {
        e.AppointmentEditDialog = new EditDialogDisabledFields();
    }
}

I hope you find this useful. Feel free to contact me if you need further help.
