Assembly: System.Windows.Forms (in system.windows.forms.dll)
A bitwise combination of Keys values that represents the key or keys to process.
Return Valuetrue if the key was processed; otherwise, false.
The DOWN ARROW key would cause the control to enter edit mode, but the EditType property of the new current cell does not indicate a class that derives from Control and implements IDataGridViewEditingControl.
This action would commit a cell value or enter edit mode, but an error in the data source prevents the action and either there is no handler for the DataError event or the handler has set the DataGridViewDataErrorEventArgs.ThrowException property to true.
