Slava,

>The error icons for the data validated in the CheckRulesHook method are displayed next to the controls. However the error icons for required fields are always displayed at the first row, not actual row. Add an AddRequiredField(“ShipCountry”) statement to the OrderRule class in the MM sample, navigate to any row and try to save a record with empty Region and Country fields. You'll see error icons in two rows instead of the current one.

I was able to duplicate this behavior...I'll check it out and get back to you.

Regards,
