For this reason (because of the problems you mention), I don't use parent-child relations between grids. You can use one of these alternatives:

Use the SET FILTER command in the child table.

Use a parameterized view in the child table.

The second alternative should be faster, especially for larger tables.

In both cases, you have to update the child table (change the filter, or requery() the view), when you change the parent record.
