Grid プロパティは、この UltraGridLayout オブジェクトが関連付けられている UltraGridBase インスタンスを返します。UltraGridLayout オブジェクトは、それが属する UltraGridBase インスタンスに戻る参照を維持します。たとえば、指定された UltraGrid タイプの ultraGrid1、ultraGrid1 == ultraGrid1.DisplayLayout.Grid は常に True に評価されます。UltraGridBase クラスからすべてが派生されるので、同じことが UltraCombo および UltraDropDown にも適用されます。
