[英]ValidationMessageFor is not showing for some fields ? MVC EF
我的 Controller ActionMethod 創建視圖是,
public ActionResult Create(int id=0)
{
Employee emp = new Employee();
ViewBag.TribeId = new SelectList(db.Tribes, "TribeId", "TribeName");
return View(emp);
}
我有 EF model 員工,
public partial class Employee
{
public int EmpIoyeeId { get; set; }
[Display(Name = "FirstName", ResourceType = typeof(Resources.Resource))]
[Required(ErrorMessageResourceType = typeof(Resources.Resource),
ErrorMessageResourceName = "FirstNameRequired")]
public string FirstName { get; set; }
[Display(Name = "Secondname", ResourceType = typeof(Resources.Resource))]
[Required(ErrorMessageResourceType = typeof(Resources.Resource),
ErrorMessageResourceName = "SecondnameRequired")]
public string Secondname { get; set; }
[Display(Name = "TribeId", ResourceType = typeof(Resources.Resource))]
[Required(ErrorMessageResourceType = typeof(Resources.Resource),
ErrorMessageResourceName = "TribeIdRequired")]
public int TribeId { get; set; }
public virtual Tribe Tribe { get; set; }
}
這里,TribeId 是 Employee 表中的 Fk 和 Employee EF class
我的查看頁面就像,
@model Structure.Employee
@using (Html.BeginForm()
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
<div class="form-group">
@Html.LabelFor(model => model.FirstName, htmlAttributes: new { @class = "control-label col-sm-4" })
<div class="col-sm-8">
@Html.EditorFor(model => model.FirstName, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.FirstName, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(model => model.Secondname, htmlAttributes: new { @class = "control-label col-sm-4" })
<div class="col-sm-8">
@Html.EditorFor(model => model.Secondname, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Secondname, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(model => model.TribeId, @Resource.TribeName, htmlAttributes: new { @class = "control-label col-sm-4" })
<div class="col-sm-8">
@Html.DropDownList("TribeId", null, htmlAttributes: new { @class = "form-control" })
@Html.ValidationMessageFor(model => model.TribeId, "", new { @class = "text-danger" })
</div>
</div>
}
現在它適用於名字和名字,但我不明白為什么它沒有顯示 TribeId 的驗證消息? 我已經檢查了資源文件以顯示一切正常的驗證消息。
希望得到您的建議。
謝謝
這就是我為使 TribeId 驗證工作所做的工作
首先在你的行動中
public ActionResult Create(int id=0)
{
Employee emp = new Employee();
ViewBag.Tribes = new SelectList(db.Tribes, "TribeId", "TribeName");
return View(emp);
}
在您看來,請使用以下內容
<div class="form-group">
@Html.LabelFor(model => model.TribeId, "tribe", htmlAttributes: new { @class = "control-label col-sm-4" })
<div class="col-sm-8">
@Html.DropDownListFor(model => model.TribeId, (IEnumerable<SelectListItem>)ViewBag.Tribes, "Select Tribe")
@Html.ValidationMessageFor(model => model.TribeId, "", new { @class = "text-danger" })
</div>
</div>
希望這可以幫助
