ListView.ColumnClick イベント

.NET Framework クラス ライブラリ リファレンス

ListView.ColumnClick イベント

ユーザーがリスト ビュー コントロール内の列ヘッダーをクリックすると発生します。

名前空間: System.Windows.Forms
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)
構文

Visual Basic (宣言)

Public Event ColumnClick As
 ColumnClickEventHandler

Visual Basic (使用法)

Dim instance As ListView
Dim handler As ColumnClickEventHandler

AddHandler instance.ColumnClick, handler

C#

public event ColumnClickEventHandler ColumnClick

C++

public:
event ColumnClickEventHandler^ ColumnClick {
    void add (ColumnClickEventHandler^ value);
    void remove (ColumnClickEventHandler^ value);
}

J#

/** @event */
public void add_ColumnClick (ColumnClickEventHandler
 value)

/** @event */
public void remove_ColumnClick (ColumnClickEventHandler
 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

ColumnClick イベントは、ユーザーが ListView コントロールの項目の詳細ビューの列ヘッダーの 1 つをクリックすると発生します (View プロパティが Details に設定されている場合)。ColumnClick イベントは、通常、クリックされた列を並べ替えの列として使用して、ListView の項目を並べ替えるために処理されます。

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

ListView コントロールの列がクリックされたときに手動で項目を並べ替える ListView コントロールが配置されたフォームを作成するコード例を次に示します。この例では、ListViewItem の比較を実行する System.Collections.IComparer インターフェイスを実装するクラスを ListViewItemComparer という名前で定義します。また、ListViewItemComparer のインスタンスを作成し、これを使用して ListView コントロールの ListViewItemSorter プロパティを設定します。ColumnClick イベント ハンドラでの Sort メソッド呼び出しでは、ListViewItemComparer に定義されているメソッドを使用し、クリックされた列を基準に、項目の並べ替えを実行します。
