I attached a demo project so you can see the problem.

When I clear all fields from a dataset associated with a TsDBGrid, I get a stack overflow.

I do not get this error when I use a regular TDBGrid.

You can add a break point to the function TacColumnTitle.IsCaptionStored to get you started.

Finally it is not quite correct.

There's no stack overflow anymore, but the grid still needs to be painted according to the informations coming from the grid's column like the caption.
