GrapeCity SPREAD for Windows Forms 12.0J サンプルコード集 > キーボード操作(入力マップ) > 編集中セルでのキー入力を検知する |
編集中セルにおいて、各Keyイベント(FpSpreadクラスのKeyDown/KeyPress/KeyUpイベント:いずれもSystem.Windows.Forms.Controlから継承)は基本的に発生しません。/p>
このような場合は、編集中に利用されるエディターコントロール(FpSpread1.EditingControl)にハンドルすることで、各Keyイベントを発生させることができます。
但し、各Keyイベントの発生条件は入力マップの定義などにも大きく依存しますので、実装の際にはあらかじめ十分な動作確認を行ってください。
