The ShowRecordPlusMinus property in TableOptions indicates whether a PlusMinus symbol should appear or not to the records. Please refer the below code snippet which avoids the Plus/Minus symbol for the parent table:
this.GridGroupingControl1.TableOptions.ShowRecordPlusMinus = false;
Me.GridGroupingControl1.TableOptions.ShowRecordPlusMinus = False
Note: This property is applicable only for nested tables.
