Hi Dan,
check out the Grid\Samples\Grouping\ResizableRows example that ships with 3.2.1.0
This sample allows you to manually change the size of a row. So, what you could do is set the height of the first row in a group to 0.
TableModel.HideRows will not work since that bypasses the CounterLogic used by the grouping engine and you therefore would get drawing and scrolling issues.
