Use the EditClose method to close programmatically the current editor. Use the Edit method to start editing a cell. Use the Editing property to check whether the control runs in the edit mode.

The following VB sample closes the editor when user hits the enter key:

Private Sub Grid1_KeyDown(KeyCode As Integer, Shift As Integer)
    With Grid1
        If Not (.Editing = 0) Then
            If (KeyCode = vbKeyReturn) Then
                .EditClose
                KeyCode = 0
            End If
        End If
    End With
End Sub

The following C++ sample closes the editor when user hits the enter key:

void OnKeyDownGrid1(short FAR* KeyCode, short Shift) 
{
	if ( *KeyCode == VK_RETURN )
		if ( m_grid.GetEditing() != 0 )
		{
			m_grid.EditClose();
			*KeyCode = 0;
		}
}

The following C# sample closes the editor when user hits the enter key:

private void axGrid1_KeyDownEvent(object sender, AxEXGRIDLib._IGridEvents_KeyDownEvent e)
{
	if (Convert.ToUInt32(e.keyCode) == Convert.ToUInt32(Keys.Enter))
		if (axGrid1.Editing != 0)
		{
			axGrid1.EditClose();
			e.keyCode = 0;
		}
}

The following VB.NET sample closes the editor when user hits the enter key:

Private Sub AxGrid1_KeyDownEvent(ByVal sender As Object, ByVal e As AxEXGRIDLib._IGridEvents_KeyDownEvent) Handles AxGrid1.KeyDownEvent
    If (Convert.ToUInt32(e.keyCode) = Convert.ToUInt32(Keys.Enter)) Then
        With AxGrid1
            If Not (.Editing = 0) Then
                .EditClose()
                e.keyCode = 0
            End If
        End With
    End If
End Sub

The following VFP sample closes the editor when user hits the enter key:

*** ActiveX Control Event ***
LPARAMETERS keycode, shift

if ( keycode = 13 ) &&vkReturn
	with thisform.Grid1.Object
		if ( .Editing() != 0 )
			.EditClose()
			keycode = 0
		endif
	endwith
