GrapeCity CalendarGrid for Windows Forms 2.0J
DataSource プロパティ (GcCalendarGrid)
使用例 

データソースを取得または設定します。
構文
Public Property DataSource As Object
public object DataSource {get; set;}

プロパティ値

データソースを示す object
既定値は null 参照 (Visual Basicでは Nothing) です。
解説
データソースにはデータベース、Web サービス、またはオブジェクトを指定することが可能で、これらを使用してデータバインドコントロールを生成できます。DataSource プロパティが設定されている場合、項目コレクションは変更できません。
