一部の情報は、リリース前に大きく変更される可能性があるプレリリースされた製品に関するものです。 Microsoft は、ここに記載されている情報について、明示または黙示を問わず、一切保証しません。
セル値が正常に書式設定されたかどうかを示す値を取得または設定します。
public:
property bool FormattingApplied { bool get(); void set(bool value); };public bool FormattingApplied { get; set; }member this.FormattingApplied : bool with get, setPublic Property FormattingApplied As Booleanプロパティ値
true セル値の書式が処理されている場合。それ以外の場合は false。 既定値は false です。
例
次のコード例では、 FormattingApplied プロパティを true に設定して、このセルの書式設定が完了したことを通知します。

注釈
CellFormatting イベントを処理する場合は、Value プロパティを設定した後、値の書式設定が不要な場合は、FormattingApplied プロパティをtrueに設定します。 イベント ハンドラーの終了時にFormattingAppliedプロパティ値がfalseされた場合、CellStyle プロパティによって返されるDataGridViewCellStyle オブジェクトのFormat、FormatProvider、NullValue、およびDataSourceNullValueプロパティによって示されるように、書式設定が値に適用されます。
