How to automatically add placeholder attribute to html input type number in mvc 4?

由 ▼魔方 西西 提交于 2019-12-03 03:07:23

See the code below: @Html.TextBox("", ViewData.TemplateInfo.FormattedModelValue, new { @class = "text-box single-line", placeholder = ViewData.ModelMetadata.Watermark }) It works because i'm using the [DataType(DataType.EmailAddress)] DataAnnotation in my view model. What doesn't works is when I use a int? variable. public class MiageQuotaRequestViewModel { [Required] [DataType
