At design time you can group nested tables only using the GroupedColumns collection editor since the drop-by area is not shown automatically. At runtime you can make the drop-by area show up by adding the folling line in your forms ctor: this.gridGroupingControl1.AddGroupDropArea("Orders"); whereas "Orders" needs to be replaced with the name of the nested table. Check out the HierarchySample and HierarchyView. They both show drop-by area for nested tables. If you need to get access to the GroupedColumns collection of a nested relation at runtime, you can use the following call: this.gridGroupingControl1.TableDescriptor.Relations[0].ChildTableDescriptor.GroupedColumns.Add("Country"); Thanks, Stefan
