'宣言 Public Property FilterOperatorDefaultValue As FilterOperatorDefaultValue
public FilterOperatorDefaultValue FilterOperatorDefaultValue {get; set;}
デフォルトでは、フィルター行にはフィルター オペランドのほかにフィルター演算子を選択するためのユーザー インターフェイスも表示されます。このユーザーインターフェイスを非表示または無効にしてユーザーがフィルター演算子を変更できないようにするには、FilterOperatorLocation プロパティを使用します。デフォルトで使用するフィルター演算子を指定するには、FilterOperatorDefaultValue プロパティを使用します。フィルター演算子 UI を有効にした場合、このプロパティの値が初期値になります。
