UltraGridを方向キーでExcelライクに操作する

InfragisticsのNetAdvantage WinFormに含まれるUltraGrid。
とても高機能で便利なのですが，Excelみたいに方向キーで操作したいと思うとコードを追加する必要があります。
グレープシティのSPREADほどExcelライクというわけではないけれど，伝票系の入力画面を作るときなどに重宝します。

Imports Infragistics.Win.UltraWinGrid

Private Sub grid1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles grid1.KeyDown

    Dim gd As UltraGrid = grid1

    Select Case e.KeyCode
        Case Windows.Forms.Keys.Up
            gd.PerformAction(UltraGridAction.EnterEditMode, False, False)
            gd.PerformAction(UltraGridAction.AboveCell, False, False)
            e.Handled = True
            gd.PerformAction(UltraGridAction.EnterEditMode, False, False)
        Case Windows.Forms.Keys.Down
            gd.PerformAction(UltraGridAction.ExitEditMode, False, False)
            gd.PerformAction(UltraGridAction.BelowCell, False, False)
            e.Handled = True
            gd.PerformAction(UltraGridAction.EnterEditMode, False, False)
        Case Windows.Forms.Keys.Right
            gd.PerformAction(UltraGridAction.ExitEditMode, False, False)
            gd.PerformAction(UltraGridAction.NextCellByTab, False, False)
            e.Handled = True
            gd.PerformAction(UltraGridAction.EnterEditMode, False, False)
        Case Windows.Forms.Keys.Left
            gd.PerformAction(UltraGridAction.ExitEditMode, False, False)
            gd.PerformAction(UltraGridAction.PrevCellByTab, False, False)
            e.Handled = True
            gd.PerformAction(UltraGridAction.EnterEditMode, False, False)
        Case Windows.Forms.Keys.Enter
            gd.PerformAction(UltraGridAction.ExitEditMode, False, False)
            gd.PerformAction(UltraGridAction.BelowCell, False, False)
            e.Handled = True
            gd.PerformAction(UltraGridAction.EnterEditMode, False, False)
    End Select

End Sub
