注釈

このクラスは DataGridViewColumn 、コントロール内の論理列を DataGridView 表します。 コントロールのコレクションを Columns 通じて列を取得できます。

DataGridViewRow内のセルDataGridViewの実際のコレクションを含むとは異なり、DataGridViewColumn主に列の幅やセル スタイルなど、列のユーザー インターフェイス (UI) の外観と動作を調整するために使用されます。 セル スタイルの詳細については、「Windows フォーム DataGridView コントロールでのセルのスタイル」を参照してください。

通常、プロパティを初期化CellTemplateして、クラスからDataGridViewColumn派生した関連する型の新しいインスタンスに派生するDataGridViewCell型。 個々のセルの外観または動作に関連するすべての列プロパティは、テンプレート セルの対応するプロパティのラッパーです。 列でこれらのプロパティのいずれかを変更すると、セル テンプレートと列内のすべてのセルの値が自動的に変更されます。 個々のセルに対して指定した値をオーバーライドするには、列の値を設定した後でセル値を設定します。

注意 (継承者)

派生元 DataGridViewColumn および派生クラスに新しいプロパティを追加する場合は、複製操作中に新しいプロパティを Clone() コピーするメソッドをオーバーライドしてください。 基底クラスの Clone() プロパティが新しいセルにコピーされるように、基底クラスのメソッドも呼び出す必要があります。
