Question

这是与Assign ValidationResult to specific field?

类似的问题

我的视图模型如下所示：

    [DisplayName("Password")]
    [Required(ErrorMessage = "Password is required")]
    [StringLength(3, ErrorMessage = "Password length Should be less than 3")]
    public string Password { get; set; }

    [DisplayName("Confirm Password")]
    [Required(ErrorMessage = "Confirm Password is required")]
    [StringLength(3, ErrorMessage = "Confirm Password length should be less than 3")]       
    public string ConfirmPassword { get; set; }


public static ValidationResult ExtendedValidation(ManageUserViewModel t)
        {
            if (t.Password == t.ConfirmPassword)
                return ValidationResult.Success;
            else
                return new ValidationResult("Your passwords must match", new[] { "ConfirmPassword" });
        }

我的观点如下：

  @Html.ValidationSummary(true, "The user details were not saved, please see the validation results below")
  @using (Html.BeginForm("Save", "Users", FormMethod.Post))
    {

       <div class="formField">
                @Html.LabelFor(model => model.Password)
                @Html.TextBoxFor(model => model.Password)
                @Html.ValidationMessageFor(model => model.Password)
            </div>

            <div class="formField">
                @Html.LabelFor(model => model.ConfirmPassword)
                @Html.TextBoxFor(model => model.ConfirmPassword)
                @Html.ValidationMessageFor(model => model.ConfirmPassword)
            </div>

但我的自定义验证错误显示在页面顶部，当我希望它显示在内。

EG，长度检查错误导致内嵌显示，我希望我确认也这样做。

谢谢，戴夫

有一个验证属性可以完全满足您的自定义验证要求。尝试添加Compare属性：

[DisplayName("Password")]
[Required(ErrorMessage = "Password is required")]
[StringLength(3, ErrorMessage = "Password length should be less than 3")]
public string Password { get; set; }

[DisplayName("Confirm Password")]
[Compare("Password", ErrorMessage = "Your passwords must match")]
[Required(ErrorMessage = "Confirm Password is required")]
[StringLength(3, ErrorMessage = "Confirm Password length should be less than 3")]       
public string ConfirmPassword { get; set; }

另外...

有时我想使用Html.ValidationMessage()添加我想要显示的其他错误。在服务器端验证期间，错误会添加到ModelState。该键与正在验证的控件的ID匹配，但您也可以添加自己的键。

您可以使用：

ModelState.AddModelError("ConfirmPassword", "You've done something wrong...");

向ConfirmPassword属性添加错误，然后会显示ConfirmPassword的验证错误。或者您可以使用其他密钥：

ModelState.AddModelError("MyError", "You've done something wrong...");

然后，您可以使用以下方式在视图中显示该错误：

@Html.ValidationMessage("MyError");
