Here is a problem with master/detail grid controls which are based on the mmGridControl. I reproduced it for the MM Northwind sample.
Go to the Properties page and navigate Order records using navigation buttons. The Order Details grid control is refreshing accordingly. Go to the list page and navigate to any record by a cursor, not navigation buttons. Go to the Properties page: all fields are refreshed, but the grid control is not. How can I go around the problem?

Thanks in advance
