コンテナ コントロールの Type。
使用例
TemplatedFirstControl という名前の template 宣言されたコントロールを作成し、このコントロールを FirstTemplateContainer という名前のコンテナと関連付ける方法を次のコード例に示します。このコード例では、テンプレートが指定されない場合はサーバー時間を表示し、テンプレートが指定される場合はテンプレートの内容を表示するカスタム コントロールが作成されます。TemplateContainerAttribute クラスが FirstTemplate プロパティに対して使用され、ContainerType プロパティが FirstTemplateContainer として指定されています。
