How to replace the plus/minus cell of the group caption row with an empty cell when there is only one record in that group?

Platform: WinForms |
Control: GridGroupingControl |
Published Date: April 30, 2011 |

By default, the GridGroupingControl shows the plus/minus symbol for all the groups whether the group contains only one record or many records. When you want to hide the plus/minus symbol for the groups that have only one record, then use the following solution.


In order to replace the Plus/Minus PushButton of the caption row, you need to handle the QueryCellStyleInfo event. In the event handler, change the PushButton CellType to Static CellType and expand the group that has only one record.



The following screenshot displays the plus/minus symbol hidden.
