asp.net mvc xval 验证

Question

您好，我是第一次使用 xval，它似乎对必填字段工作正常， 但是我遇到了一些问题 首先，它似乎没有验证布尔值，而且客户端验证对我不起作用，这对我来说不是一个主要问题，我真正需要工作的是 stringlength 属性。它似乎做了一些事情，因为超过字符串长度时没有发布表单，但是没有向用户显示错误消息，这显然不是我想要的，有没有人能够成功地做到这一点？

我的模型是这样的

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;
namespace PitchPortal.Core
{
    public class DocumentMetadata
    {

        //[Required]
        // public bool visibility { get; set; }


        [Required,StringLength(10, ErrorMessage = "title is too long")]
        public string title { get; set; }

        [Required, StringLength(10, ErrorMessage = "description is too long")]    
        public string description { get; set; }

        [Required, StringLength(10, ErrorMessage = "summary is too long")]    
        public string summary { get; set; }

    }
}

html 是这样的

<div id="results" title="Upload results"/> 
  <form id="myForm"  action="<%=Url.Action("New") %>"  method="post" enctype="multipart/form-data">  
    <% Html.EnableClientValidation(); %>

    <%= Html.ValidationSummary() %>
    <table>
         <tr>
               <td> <%=Html.Label("File")%></td>
               <td>
                    <input type="file" id="file1" name="fileUpload" /> <br />
                    <%=Html.SubmitButton<DocumentController>(x => x.Upload(), "GetImage", "")%>
               </td>
               <td>
                    <%=Html.ValidationMessage("file1")%>
               </td>
         </tr>   
         <tr>
                <td> <%=Html.Label("Visible")%></td>
                <td>
                     <%= Html.RadioButton( "visibility",true,true)  %>true
                     <%= Html.RadioButton("visibility", false)%>false
                </td>
                <td>
                     <%= Html.ValidationMessage("visibility")%>   
                </td>

         </tr> 
         <tr>   
                <td> <%=Html.Label("Title")%></td>
                <td> <%=Html.TextBox("doc.title")%></td>         
                <td> <%= Html.ValidationMessage("doc.title")%></td>
         </tr>
         <tr>   
                <td> <%=Html.Label("Description")%></td>
                <td><%= Html.TextArea("doc.description")%></td> 
                <td><%= Html.ValidationMessage("doc.description")%></td>
         </tr>
         <tr>
                <td> <%=Html.Label("Summary")%></td>
                <td> <%= Html.TextArea("doc.summary")%></td>  
                <td> <%= Html.ValidationMessage("doc.summary")%></td>
         </tr>
         <tr>  
                <td> <%=Html.Label("Filetype")%></td>
                <td> <%= Html.DropDownList("Filetype_id", (IEnumerable<SelectListItem>)ViewData.Model.AllFiletypesList)%> </td>

                <td> <%= Html.ValidationMessage("doc.Filetype_id")%> </td>
         </tr>
         <tr>
                <td> <%=Html.Label("Category")%></td>
                <td><%= Html.DropDownList("cat.parent_id", (IEnumerable<SelectListItem>)ViewData.Model.AllCategoriesList, "-please select item-", new { className = "unselected" })%> </td>
           <td><%= Html.ValidationMessage("cat.parent_id")%> </td>
         </tr>

      <% 
          if (Session["TempFolder"] == null)     
          {
                 for (int i = 1; i < 6; i++) 
                 { %>
                     <tr>
                         <td> <%=Html.Label("Shot "+i.ToString()) %> </td>
                         <td><input type="file" id="image_<%= i.ToString() %>" name="image_<%= i.ToString() %>" /></td>
                     </tr>
        <%       } 
          }%>

        <tr>
              <td><input type="submit"  value="save"/></td>
        </tr>
</table>
</form>    
</div>

你忘了放：

<%= Html.ClientSideValidation("doc", typeof(Document))
        .UseValidationSummary("validationSummary") %>

并把你的<%= Html.ValidationSummary() %> bettween tags <div id="validationsummary">and </div>
