TTMSFNCDataGridDataGetCellDataEvent Event Type

Fired when a cell value is fetched, so the handler can supply or replace it.

API unit family: TMSFNCDataGridData

Remarks

The replacement is returned to the caller but not stored in the cell. Use this for virtual or computed cells; the handler runs for every fetch, so keep it fast.

Parameters

Name	Description
Sender	Data object that fetches the value.
ACell	Column and row of the cell.
AData	On entry, the stored value (after an attached data adapter had a chance to provide it). Assign a new value to replace what is returned.
