Operating with system defined buttons in form Action pane

Say, we have to reference Edit button.

For this we use the macro #define.SystemDefinedViewEditButton('SystemDefinedViewEditButton')

The whole list is present in SysSystemDefinedButtons macro


Code snippet for your active method in name_DS

int active()
        {
            
            #SysSystemDefinedButtons
 
            ret = super();
 
         < ... >
            FormCommandButtonControl editButton = element.control(element.controlId(#SystemDefinedViewEditButton)) as FormCommandButtonControl;
            editButton.enabled(name_ds.allowEdit());
 
            return ret;
        }
