GridGroupingControl - How to hide a row in GGC

Hi! Please can anybody tell me how to hide a row in a GGC? In the attached file you can see GGC with several groups. If a group is expanded you can see that the first row contains the same data as the caption row. Now I''d like to hide that row with similar data. Right now I do it like this: private void Table_GroupExpanded(object sender, GroupEventArgs e) { Group group = e.Group; GridRangeInfo gri = this.gridGroupingControlMarketData.TableModel.RecordFieldToRangeInfo( group.GetFirstRecord(), "Symbol" ); int rowIdx = gri.Top; if ( group.Records.Count > 0 ) { HideDuplicatedRow( rowIdx, true ); } } private void HideDuplicatedRow( int rowIdx, bool hide ) { GridModelHideRowColsIndexer indexer = this.gridGroupingControlMarketData.TableModel.HideRows; indexer.SetRange( rowIdx, rowIdx, hide ); } The problem is if I start at the bottom to expand the groups it hides the wrong rowa. If I begin at the top of the table it works. Thank you for your help! Dan groupinggrid_4548.zip

Hi Dan, check out the Grid\Samples\Grouping\ResizableRows example that ships with 3.2.1.0 This sample allows you to manually change the size of a row. So, what you could do is set the height of the first row in a group to 0. TableModel.HideRows will not work since that bypasses the CounterLogic used by the grouping engine and you therefore would get drawing and scrolling issues.
