コンボ ボックス - カスケード
このサンプルでは、3 つのカスケードするコンボ コントロールの使用方法を紹介します。
このサンプルは CTP 機能を使用しています。製品版では、API や動作が変更される場合があります。
国を選択すると、データ フィルタリングが自動的に開始されます。

市
このサンプルは、より大きい画面サイズのためにデザインされました。
モバイル デバイスで画面を回転、フル サイズ表示、またはその他のデバイスにメールで送信します。
たとえば、多国籍企業のオフィスを検索します。前のコンボの値を選択すると、次のコントロールの値は前のコンボの値に基づいて自動的にフィルターされます。このサンプルでは、igCombo コントロールのインスタンスを別のデータ ソースにバインドし、igCombo をカスケード データ ソースにバインドする方法を紹介します。最初の 2 つの igCombo インスタンスの結果は同じです。カスケード igCombo のプロパティの詳細について、「カスケード コンボ」のトピックを参照するか、API ドキュメントを参照してください。
