不显示MVC4验证错误信息 [英] Validation error message not displaying MVC4

问题描述

我使用MVC4。

验证失败，但都没有得到验证显示错误消息。

Validation is failing but validation error messages are not getting displayed.

这是我的模型。

public class Configuration
{
    public int Id { get; set; }

    [Required(AllowEmptyStrings = false, ErrorMessage = "Site name is required.")]
    [MinLength(6, ErrorMessage = "Name should be at least 6 characters.")]
    public string SiteName { get; set; }
}

控制器。

[HttpPost]
    public ActionResult Create(Configuration configItem)
    {
        if (ModelState.IsValid)
        {
            // do something.
        }
        return View("Index", configItem);
    }

查看是

@model Models.SitesConfig.Configuration
@{
ViewBag.Title = "Sites Configurations";
}
<div>
    @Html.ActionLink("Sites List", "List", "SiteConfig")
</div>
@using (Html.BeginForm("Create", "SiteConfig", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    <fieldset>
        <legend>New Satellitesite</legend>
        <div>
            @Html.LabelFor(m => m.SiteName, "Name")
            @Html.TextBoxFor(m => m.SiteName)
            @Html.ValidationMessageFor(m=>m.SiteName)
        </div>
        <br />

        <input type="submit" value="Save" />

    </fieldset>
}

请也建议我，如果有做验证的没有更好的办法。

Please also suggest me if there is any better way of doing the validations.

推荐答案

我不知道是什么问题。清理并生成应用程序之后，我能够看到错误消息。

I don't know what was the problem. After clean and build the application, I am able to see the error message.
