mvc中的數據註釋

Question

我想在我的MVC項目中使用數據註解。

我已經建立了我的模型，並添加了所有適當的註解。我有我的看法和控制器，並嘗試了很多方法，但我沒有得到任何結果。

當我點擊提交按鈕確認發射，但錯誤不傳遞消息顯示解決它。

Answer 1

也許你不交後，你的代碼使用ModelState.IsValid。嘗試，因爲

public ActionResult ControllerName(EmployeeInfo obj) 
{ 
    if (ModelState.IsValid) 
    { 
     //// Your Code 
    } 
} 

Answer 2

由於您使用的是一個員工的信息，你不必使用EmployeeViewModel代替你可以使用EmployeeInfo並通過相同的控制器來查看。

變化（查看）：

@model AllExamples.DTO.EmployeeInfo 
@{ 
    ViewBag.Title = "Home Page"; 
} 
<script src="~/Scripts/jquery-1.10.2.js"></script> 
<script src="~/Scripts/jquery.validate.js"></script> 
<script src="~/Scripts/jquery.validate.unobtrusive.js"></script> 

@using (Html.BeginForm("Index", "Home", FormMethod.Post, new { @class = "form-horizontal", role = "form" })) 
{ 
    @*@Html.AntiForgeryToken()*@ 

    @Html.ValidationSummary(false) 

    <div class="form-group"> 
     @Html.Label("Employee Name", new { @class = "col-md-2 control-label" }) 
     <div class="col-md-10"> 
      @Html.TextBoxFor(m => m.EmployeeName, new { @class = "form-control", Name = "EmployeeName" }) 
      @Html.ValidationMessageFor(m => m.EmployeeName) 
     </div> 
    </div> 
    <div class="form-group"> 
     @Html.Label("Email ID", new { @class = "col-md-2 control-label" }) 
     <div class="col-md-10"> 
      @Html.TextBoxFor(m => m.EmailID, new { @class = "form-control",Name= "EmailID" }) 
      @Html.ValidationMessageFor(m => m.EmailID) 
     </div> 
    </div> 
    <div class="form-group"> 
     @Html.Label("Contact Number", new { @class = "col-md-2 control-label" }) 
     <div class="col-md-10"> 
      @Html.TextBoxFor(m => m.ContactNumber, new { @class = "form-control", Name = "ContactNumber" }) 
      @Html.ValidationMessageFor(m => m.ContactNumber) 
     </div> 
    </div> 

    <div class="form-group"> 
     <div class="col-md-offset-2 col-md-10"> 
      <input type="submit" class="btn btn-default" value="Save" /> 
     </div> 
    </div> 
}
