TTMSFNCDataGridCellGetControlExtraPropertiesEvent Event Type
Signature of the cell-level request for extra property names that become part of the control bitmap cache key.
API unit family: TMSFNCDataGridCell
Remarks
Raised every time the cache key is built, so keep the handler fast. The grid routes it to TTMSFNCCustomDataGrid.OnGetCellControlExtraProperties.
