Asp.net mvc 设置ValidationMessageFor@Html.TextBox

Asp.net mvc 设置ValidationMessageFor@Html.TextBox,asp.net-mvc,validation,razor,Asp.net Mvc,Validation,Razor,我有以下代码: @using (Html.BeginForm("Search", "Home")) { @Html.ValidationSummary(true, "", new { @class = "text-danger" }) @Html.AntiForgeryToken() @Html.TextBox("Search_Data", ViewBag.FilterValue as string, new { @class = "search-box", required = "

我有以下代码:

@using (Html.BeginForm("Search", "Home"))
{
  @Html.ValidationSummary(true, "", new { @class = "text-danger" })
  @Html.AntiForgeryToken()
  @Html.TextBox("Search_Data", ViewBag.FilterValue as string, new { @class = "search-box", required = "required" })
  <input type="image" src="~/Images/Search.gif" alt="Find Everything Catholic" style="display:inline" />
  @Html.Raw(MyAsYouType.getHtml())
}
使用(Html.BeginForm(“搜索”、“主页”)) { @Html.ValidationSummary(true,“,new{@class=“text danger”}) @Html.AntiForgeryToken() @TextBox(“Search_Data”,ViewBag.FilterValue作为字符串,new{@class=“Search box”,required=“required”}) @Html.Raw(MyAsYouType.getHtml()) }
表单未提交,但我无法确定是否显示错误消息

我的模型:

[DbFunction("ECdevEntities", "Main_Search")]
public virtual IQueryable<Main_Search_Result> Main_Search(string keyword)
{
  var keywordParameter = keyword != null ?
    new ObjectParameter("keyword", keyword) :
    new ObjectParameter("keyword", typeof(string));
  return ((IObjectContextAdapter)this).ObjectContext.CreateQuery<Main_Search_Result>("[ECdevEntities].[Main_Search](@keyword)", keywordParameter);
}
[DbFunction(“ECdevEntities”,“Main_Search”)]
公共虚拟IQueryable主搜索(字符串关键字)
{
var keywordParameter=关键字!=null?
新的ObjectParameter(“关键字”,关键字):
新的ObjectParameter(“关键字”,typeof(字符串));
返回((IObjectContextAdapter)this.ObjectContext.CreateQuery(“[ECDeventies].[Main\u Search](@keyword)”,关键字参数);
}

这是我在模型中所做的

public class ContactModel
    {
        [Required (ErrorMessage="Name is Required")]
        public string ContactName { get; set; }

        [Required(ErrorMessage = "Subject is Required")]
        public string Desc { get; set; }

        [Required(ErrorMessage = "Email Address is Required")]
        [RegularExpression(".+\\@.+\\..+", ErrorMessage = "Email Address is not Valid")]
        [DataType(DataType.EmailAddress)]
        public string Email { get; set; }

        [Required(ErrorMessage = "Message is Required")]
        public string Message { get; set; }

        public bool MessageSent { get; set; } 

        //public string PType { get; set; }
    }
}
这是我的表格

@using (Html.BeginForm())
         {
            @Html.ValidationSummary(true) 
                <label for="contactname">Name</label>
                @Html.TextBoxFor(model => model.ContactName, new { @class = "textfield" })<span class="require"> *</span>
                @Html.ValidationMessageFor(model => model.ContactName) 
                  <label for="contactsubject">Subject</label> 
                @Html.TextBoxFor(model => model.Desc, new { @class = "textfield" })<span class="require"> *</span>
               @Html.ValidationMessageFor(model => model.Desc) 
                   <label for="contactemail">Your E-mail</label> 
                @Html.TextBoxFor(model => model.Email, new { @class = "textfield" })<span class="require"> *</span>
                @Html.ValidationMessageFor(model => model.Email) 

                  <label for="contactmessage">Your Message</label> 


              @Html.TextAreaFor(model => model.Message, new { @class = "textarea" })
                <span class="require"> *</span>
                  @Html.ValidationMessageFor(model => model.Message ) 
                    <a href="javascript:{}" onclick="document.getElementById('form0').submit(); return true;" class="button"> 
                        <span>Send Message</span></a>


         } 
@使用(Html.BeginForm())
{
@Html.ValidationSummary(true)
名称
@Html.TextBoxFor(model=>model.ContactName,新的{@class=“textfield”})*
@Html.ValidationMessageFor(model=>model.ContactName)
主题

@Html.ValidationMessageFor(model=>model.Desc)
你的电子邮件

@Html.ValidationMessageFor(model=>model.Email)
你的信息

} 

希望它能在某种程度上帮助您……

表单未提交,但我无法确定是否显示错误消息。??这会混淆您的表单是否提交?是的,如果有输入,它将提交,如果为空,它不会按预期提交,但我尝试在提交失败时显示一条错误消息。好的,我将给您一些示例代码,这些代码与您的示例不太相关,但会给您一个想法。我尝试过,但我的模型不是标准的。搜索_数据字段不是来自数据库,而是作为关键字值传递。请参见模型。您可以在模型中使用类似的内容,然后@if(ViewData.ModelState.IsValid){…}
