TTMSFNCDataGridDataGetCustomGroupCallback Event Type

Supplies the group value of a cell during grouping, so rows can be grouped on a derived value.

API unit family: TMSFNCDataGridData

Remarks

Rows that return the same value form one group, for example the first letter of a name or the year of a date. When the callback is supplied, TTMSFNCDataGridData.OnGetCustomGroup is not fired.

ACell	Column and row of the grouped cell.
AData	Raw cell value.
