c# - フィールド値に基づくカスタム表示注釈

Question

フィールド値に基づいて、カスタムラベルを表示する必要があるビューがあります。

ViewModel：

public class CreateAdViewModel
{
     public int Operation_Id { get; set; } 

     [Display(ResourceType = typeof(HeelpResources), Name = "AdViewModel_Price_Label")]
     public decimal Price { get; set; }
}

意見：

    <div id="price">
        @Html.DisplayNameFor(m => m.Price)
        @Html.TextBoxFor(m => m.Price) €
        @Html.ValidationMessageFor(m => m.Price)
    </div>

表示したい：

"Price: "  if Operation_Id = 1 (For the Sale of a Car)

と

"Price Up To: "  if Operation_Id = 2 (For someone looking for a car until value XX €)

Answer 1

2つのプロパティはどうですか:

public class CreateAdViewModel
{
    public int Operation_Id { get; set; }

    [Display(ResourceType = typeof(HelpResources), Name = "AdViewModel_Price_Label")]
    public decimal? Price { get; set; }

    [Display(ResourceType = typeof(HelpResources), Name = "AdViewModel_MaxPrice_Label")]
    public decimal? MaxPrice { get; set; }
}

ビュー内：

<div id="price">
    @if (Operation_Id == 1)
    {
        @Html.DisplayNameFor(m => m.Price)
        @Html.TextBoxFor(m => m.Price) €
        @Html.ValidationMessageFor(m => m.Price)
    }
    else
    {
        @Html.DisplayNameFor(m => m.MaxPrice)
        @Html.TextBoxFor(m => m.MaxPrice) €
        @Html.ValidationMessageFor(m => m.MaxPrice)
    }
</div>
