Let me elaborate further. The datasource is a DataSet with 3 related Tables. Tables 1 and 2 - always have records, but table 3 may or may not have related tables. Hod do I force the GGC to hide the Headers of the 3 tables whne there no related records. Please see attached screenshot. Thank you

Hi, Please try this code private void gridGroupingControl1_RecordExpanded(object sender, Syncfusion.Grouping.RecordEventArgs e) { if(e.Record.ChildTableGroupLevel == 1) { int ExpandedRecordCount = e.Record.GetNestedTablesVisibleCount(); int rowIndex = this.gridGroupingControl1.Table.NestedDisplayElements.IndexOf(e.Record); if( ExpandedRecordCount == 2) { ExpandedZeroRecord.Add(e.Record); this.gridGroupingControl1.TableModel.RowHeights[ rowIndex + 1 ] = 0; } } } Here is a sample for implementing it. GroupingMaster.zip Let me know if you need any further assistance. Regards, Haneef

Thank you for the reply. I understand approach, but this does not work for my case. My 3 child table is always expanded - and the RecordExpanded event fires only for ChildTableGroupLevel=0; What other event can I use to set RowHeight=0? Thank you
