Maybe the problem will become simpler if you rethink the approach. Why do you have a parent-child relation in the same grid? You might instead use two grids. Or a grid for the child table and separate controls such as textboxes for the parent record?

>>To expand on Naomi's reply - one way might be to store yourGrid.Recordsource's current key value in some property in yourGrid.AfterRowColChange(), and then evaluate that property in an expression stored in a yourGrid.Dynamic* property.
