Sorry for not being specific enought with the suggested solution. With this approach, you should not
set appointment.AllowEdit to false. In the FormCreated event I find the controls in the default advanced form and set properties such as Enabled, Visible and Text. This way I disable the basic and advanced control panels, hide the update button and change the text of the cancel button to "close". Please, let me know if I have to provide more details.
