Combobox field in GridGroupingGrid

[Administrator]

Is it possible to have a combobox filled with customers in an hierarchical grid?

I have implemented a combobox in a griddataboundgrid and this seems to work well but what about an hierarchical grid. I would like to set the column''s datasource to a datatable but I can''t find the datasource property for the column in this type of grid. Any help?
Thanks a lot

You set the DataSource, CellType, ValueMember and DisplayMember properties in the column''s Appearance object.

this.gridGroupingControl1.TableDescriptor.Columns["Col1"].Appearance.AnyRecordFieldCell.CellType = "ComboBox";
