I hAve a dataset with two tables are joined by relation.
I Use this dataset as dataSource for GridGroupingControl(2.0.5.0).
How can I turn on grouping for the nested tables?

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");
