如何在Asp.Net Mvc 4中为下拉列表设置客户端验证 [英] How Do I Set Client Side Validation For Drop Down List In Asp.Net Mvc 4

问题描述

这是我的控制器代码

this is my controller code

List<SelectListItem> liEducation = new List<SelectListItem>();

         liEducation.Add(new SelectListItem { Text = "Select", Value = "0" });

         liEducation.Add(new SelectListItem { Text = "Post Graduation", Value = "Post Graduation" });

         liEducation.Add(new SelectListItem { Text = "Graduation", Value = "Graduation" });

         liEducation.Add(new SelectListItem { Text = "Diploma", Value = "Diploma" });

         liEducation.Add(new SelectListItem { Text = "HSC", Value = "HSC" });

         liEducation.Add(new SelectListItem { Text = "SSC", Value = "SSC" });

         liEducation.Add(new SelectListItem { Text = "Other", Value = "Other" });

         ViewData["Education"] = liEducation;

//这是我的观点

// this is my view

@Html.DropDownListFor(m => m.Education, ViewData["Education"] as List<SelectListItem>, new { @id = "Education", style = "width:150px" })
                             @Html.ValidationMessageFor(m => m.Education)

//这是我的模型

// and this is my model

public class Education
     {
         [Required(ErrorMessage = "Please Select Education")]
         public int? ID { get; set; }
         public string Name { get; set; }
     }

我想显示错误msg如果下拉选择索引为0

I want to show error msg if dropdown selected index is 0
