DetailsView.ItemInserted イベント

メモ : このイベントは、.NET Framework version 2.0 で新しく追加されたものです。

DetailsView コントロール内の Insert ボタンがクリックされた場合に、挿入操作後に発生します。

名前空間: System.Web.UI.WebControls
アセンブリ: System.Web (system.web.dll 内)
構文

Visual Basic (宣言)

Public Event ItemInserted As
 DetailsViewInsertedEventHandler

Visual Basic (使用法)

Dim instance As DetailsView
Dim handler As DetailsViewInsertedEventHandler

AddHandler instance.ItemInserted, handler

public event DetailsViewInsertedEventHandler ItemInserted

C++

public:
event DetailsViewInsertedEventHandler^ ItemInserted {
    void add (DetailsViewInsertedEventHandler^ value);
    void remove (DetailsViewInsertedEventHandler^ value);
}

/** @event */
public void add_ItemInserted (DetailsViewInsertedEventHandler
 value)

/** @event */
public void remove_ItemInserted (DetailsViewInsertedEventHandler
 value)

JScript

JScript では、イベントは使用できますが、新規に宣言することはできません。

解説

ItemInserted イベントは、DetailsView コントロール内の Insert ボタンがクリックされた場合に、挿入操作の後で発生します。これにより、このイベントが発生するたびにカスタムルーチン (挿入操作の結果を確認するなど) を実行するイベントハンドラを提供できます。

DetailsViewInsertedEventArgs オブジェクトがイベントハンドラに渡され、これにより影響を受けた行数および発生した例外を確認できます。ExceptionHandled プロパティを設定することにより、イベントハンドラで既に例外が処理されたかどうかを示すこともできます。挿入操作の後でコントロールを挿入モードのまま維持するには、KeepInInsertMode プロパティを true に設定します。

イベント処理の詳細については、「イベントの利用」を参照してください。

使用例

ItemInserted イベントを使用して、DetailsView コントロールが挿入操作を実行した後で GridView コントロールを最新表示する方法のコード例を次に示します。これにより、GridView コントロールは常に DetailsView コントロールと同期されます。

Visual Basic

      If e.Values(i) IsNot Nothing Then
        e.Values(i) = Server.HtmlEncode(e.Values(i).ToString())
