| Post subject: | Manual Grouping in DBGridEh |
Hello friends out there, I'm in need to manually setup grouping in DBGridEh. This is needed, as we usually modify the SQL statement accessing the SQL-Server. However, this kills the complete grouping (underlying MemTableEh is closed thus losing all the Fields from DBGridEh.DataGrouping.GroupLevels). So we need to restore this manually. But: There is no "ColumnName" in any of the properties accessible by code - this property only exists in Designer. As usual the example is ultra simple showing only the extreme basics, Docs do not tell us anything more. So: How do we restore the grouping in code ? Thanks for help ! |

Hello You can use TGridDataGroupLevelEh.Column to assign column for a GroupLevel. Here is an code example: Code: procedure TForm1.Button1Click(Sender: TObject); var grLevel: TGridDataGroupLevelEh; begin DBGridEh1.DataGrouping.Active := False; grLevel := DBGridEh1.DataGrouping.GroupLevels.Add; grLevel.Column := DBGridEh1.FieldColumns['Capital']; DBGridEh1.DataGrouping.Active := True; end; TDBGridEh.FieldColumns finds and returns column by column.FieldName property. |
