Hello,

I read of someone removing the (none) and (any) options from the resources dropdown on the AppointmentEdit form, what I like is to keep (none) and if the user does not select a resource other than (none) prompt the user to select a valid resource.  I was trying the ApplySettingsToEvent method and it does not look to be firing when I close the Apppointment edit form.  Using VS2008 RadScheduler 2012.1.321.20 .

Thanks

Hi Kerry,

Thank you for contacting us.

In your case the best choice seems to be to create a custom EditAppointmentDialog:
public class MyEditAppointmentDialog : EditAppointmentDialog
{
    private bool canceled;
 
    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);
 
        this.buttonCancel.MouseDown += ButtonCancel_MouseDown;
    }
 
    void ButtonCancel_MouseDown(object sender, MouseEventArgs e)
    {
        canceled = true;
    }
 
    protected override void OnClosing(CancelEventArgs e)
    {
        base.OnClosing(e);
        if (this.cmbResource.SelectedItem.Text == "None" && !canceled)
        {
            e.Cancel = true;
            MessageBox.Show("Select a different value");
        }
 
        canceled = false;
    }
}

You can use it in the AppointmentEditDialogShowing event of RadScheduler:
void scheduler_AppointmentEditDialogShowing(object sender, AppointmentEditDialogShowingEventArgs e)
{
    e.AppointmentEditDialog = new MyEditAppointmentDialog();
}

With this dialog whenever one tries to leave the form with a selected resource "None" he will not be able to, unless the cancel button is pressed.

I hope this helps.

Regards,
George

PLEASE IGNORE MY POST BELOW. NOT SURE WHAT CHANGED BUT IS WORKING. THANKS.

I used the code you have provided below to check if a control in my appointment dialogue is populated or not. If it is not I cancel the closing using e.Cancel in the OnClosing event function.

However, I have found the following. Once the event is cancelled, the OnClosing event does not fire subsequently (fires once only) if the Cancel button is selected. When I say does not fire, it does not even reach the break point I have placed in the beginning of the OnClosing function.

Please help.

Thanks,
Vijay
