Declaration

procedure EditorTextChanged(const aCol: Integer; const aRow: Integer; 
 const aText: string); override

Arguments

Description

EditorTextChanged is an overridden method in TCustomDBGrid. It re-implements the method from the ancestor class, and does not call the inherited method.

EditorTextChanged is used to apply a cell value which was modified in the Editor for the control to the field with the value for the cell. The modified value is stored in a temporary buffer by calling SetEditText, and is eventually applied to the database field in the UpdateData method.

EditorTextChanged is called from methods in cell editor classes, like TStringCellEditor and TPickListCellEditor, when their Change or Select methods are executed.

The cell value is not updated when the grid control or the cell Editor has its ReadOnly property set to True.

EditorTextChanged calls the EditingColumn method prior to exit to update both the column number changed in the grid and the Modified property in the DataLink for the control.
