TTMSFNCDataGridDatabaseAdapter.OnDataToField Event

Fires when an edited cell value is about to be written to its dataset field.

API unit family: TMSFNCDataGridDatabaseAdapter Declaring type: TTMSFNCDataGridDatabaseAdapter Inherited from: TTMSFNCCustomDataGridDatabaseAdapter

Syntax

FMX.TMSFNCDataGridDatabaseAdapter.hppPascalC++

OnDataToField: TTMSFNCDataGridDatabaseAdapterDataToFieldEvent;

__property TTMSFNCDataGridDatabaseAdapterDataToFieldEvent OnDataToField = {read=FOnDataToField, write=FOnDataToField};

Remarks

The dataset is already in edit (or insert) mode when this fires; the record is not posted by the adapter here. By default the adapter uses the key of the selected lookup item when the editor is a lookup combo box, calls the field's OnSetText when assigned, and otherwise assigns the value through AsVariant (AsDateTime for timestamp fields).

Use this to convert display formats back to stored values, for example to strip a currency symbol. The reverse direction is OnFieldToData.
