>When working with a class drived from mmMaintenanceForm we see the error provider icon on the datagrid but we don't see the same icons from the other controls which are contained in the properties tab. Did you Notice this problem?
You should see error icons next to all controls for which rules are broken. Do you have a specific example of a rule you have set up that is broken, but the icon is not appearing?
