Question

我在编辑屏幕上显示字段。有问题的字段来自模型实体列表。如果我修改了所有屏幕字段的值并按提交，则没有问题。但是，如果存在任何未修改的字段，则会显示RegularExpression消息，即使该条目有效。

ValueDesc字段就是问题。

另外，有没有办法允许在编辑屏幕上输入零而不是添加屏幕？

同样的模型在我的添加屏幕上正常工作。

以下是一些代码：

public class ModLenBinRefModelEntity : IEntityModel
{
    public int AtcId { get; set; }
    public List<LengthBinRefModelEntity> LengthBinReferences { get; set; }

public class LengthBinRefModelEntity : IEntityModel
{
    public short BinId { get; set; }

    [Required(ErrorMessage = "Bin Number is required")]
    [Display(Name = "Bin Number")]
    [RegularExpression(@"^[1-9]\d*", ErrorMessage = "Bin Number must be 1 or greater")]
    public short BinNumber { get; set; }

    [Required(ErrorMessage = "Bin Value Description is required")]
    [Display(Name = "Value Description")]
    [DisplayFormat(DataFormatString = "{0:N1}", ApplyFormatInEditMode = true)]
    [RegularExpression(@"^[1-9]\d*", ErrorMessage = "Value Desc must be 1 or greater")]
    public decimal ValueDesc { get; set; }

...

        </tr>

        @for (int i=0; i<Model.LengthBinReferences.Count; i++)

未编辑字段时触发ValidationMessageFor
