数字だけを受け入れるモデルのプロパティにRegex式を追加しました。動的に追加された要素の検証エラー
public class MaterialsViewModel
{
[Display(Name = "Material")]
public string MaterialName { get; set; }
[Range(typeof(int), "0", "999")]
[RegularExpression(@"^\d+$", ErrorMessage = "Please enter proper value")]
public int? Quantity { get; set; }
[RegularExpression(@"^\d+$", ErrorMessage = "Please enter proper value")]
public double? Cost { get; set; }
public IEnumerable<SelectListItem> CategoryList { get; set; }
public int SelectedCategory { get; set; }
public string SelectedCategoryName { get; set; }
}
私はここで私がコントロールを追加することができます私の見解を持っている動的

問題は、私は上のいくつかの文字列（ 'SS'）を入れてみましたです数量とコストのテキストボックスで検証が有効かどうかを確認すると、The value 'ss' is not valid for QuantityとThe value 'ss is not valid for Cost.が表示されますが、それはPlease enter proper valueである必要があります。また、検証が行われるたびに、Add Materialリンクに別のnewMaterialを追加することはできません。
answerと、またDotNetFiddleを試してみましたが、まだ多少の誤差があります。
を移入するためにあなたのGETメソッドから呼び出され
注意する必要があります私のビューが戻ってきたら、私はもう新しいマテリアルを追加することができませんでしたが、スコープを追加できます。この原因は何ですか？ – progammer101
あなたのコードをもっと詳しく調べてください。また、あるタイプのデフォルトメッセージを変更する方法を示すリンクを追加します。 –
また、3つのAdd Materials要素を入力なしで作成しようとしましたが、検証を確認してビューを返すだけでした。1材料要素を追加してください。3 – progammer101
