HOWTO: custom draw cell?

I''d like to register a class of cell and handle its drawing myself. Can''t see how to do this.

You would derive a cellrenderer class and a cellmodel class like you would do with a GridControl or GridDataBoundGrid. Then you could register the cell model class using this.gridGroupingControl1.TableModel.CellModels.Add. Here is a sample that shows a button in Column header by deriving a cell type. If you want to do your own drawing, you would override the Draw method in the renderer and do it there.
