QueryCellFormattedText event is not invoked for child tables in GridGroupingControl. Example: take HierarchySample Add to the constructor: this.groupingGrid1.TableModel.QueryCellFormattedText += new GridCellTextEventHandler(TableModel_QueryCellFormattedText); Add to Form: private void TableModel_QueryCellFormattedText(object sender, GridCellTextEventArgs e) { Console.WriteLine(e.Value.ToString()); } Observe debug output, you will notice that only values for "Products" table are ever displayed. IS there any way to have this event triggered for the child tables as well ?

There are different TableModels for each nested level, so you have to subscribe to the event for each level. We will eventually add a TableModelQueryCellFormattedText event to GridGroupingControl. What you can do now is loop through relations and then wire the event for each nested TableModel. You can iterate through groupingControl.TableDescriptor.Relations and then get a reference to the TableModel with groupingControl.GetTableModel(relationDescriptor.ChildTableName). Or if you know the names of the tables in your dataset, you can also call also groupingControl.GetTableModel(tableName). Once you have the GridTableModel you can wire the event.
