{
    FormBuildCommandButtonControl   cancelButton;
    ;
    dialog = super();

    //Add dialog fields

    cancelButton = dialog.formBuildDesign().control('CancelButton');

    //Disable the Cancel button
    cancelButton.enabled(false);

    //Hide the Cancel button
    cancelButton.visible(false);
