シンタックス
public class CellsCollection : Infragistics.Shared.KeyedSubObjectsCollectionBase
解説

このプロパティは、Cell オブジェクトへの参照を取得するために使用できる Cell オブジェクトのコレクションへの参照を返します。Row オブジェクトでは行に属し、Selected オブジェクトでは現在選択されています。この参照を使用して、返されたコレクションのプロパティまたはメソッドだけでなく、コレクション内のオブジェクトのプロパティまたはメソッドにもアクセスできます。

Row オブジェクトでは、返されるコレクションは、行を構成するセルで動作する方法を提供します。

選択されたオブジェクトは、セルが選択および選択解除される時、その対応する Cell オブジェクトが追加され、このプロパティによって返される SelectedCells コレクションから削除されます。セルが選択または選択解除されると、BeforeSelectChange イベントが生成されます。

返されるコレクションの Count プロパティは、行に属するか、現在選択されているセルの数を決定するために使用されます。
