Using sub records in a grouping grid, a "+" is displayed next to every record in the top most dataset, even when there are no records contained in the subrecords for it. Can this behavior be worked around?

Randy, Try handling the QueryCellStyleInfo event as follows: private void gridGroupingControl1_QueryCellStyleInfo(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableCellStyleInfoEventArgs e) { if (e.TableCellIdentity.TableCellType == GridTableCellType.RecordPlusMinusCell) { Record r = e.TableCellIdentity.DisplayElement.ParentRecord as Record; if (r != null && r.NestedTables.Count > 0 && r.NestedTables[0].ChildTable.GetFilteredRecordCount() == 0) { e.Style.CellType = "Static"; } } } Then, no button should be displayed. Let me know if you run into problems. Thanks, Stefan Hoenig
