            @Html.DropDownList("sex", new SelectList(Enum.GetValues(typeof(enumSex))), new { @class = "form-control",data_bind="value: Sex"})

1、mvc htmlhelper 中加入data-属性，应改为data_

This problem has been addressed in ASP.Net MVC 3. They now automatically convert underscores in html attribute properties to dashes. They got lucky on this one, as underscores are not legal in html attributes, so MVC can confidently imply that you‘d like a dash when you use an underscore.

For example:

@Html.TextBoxFor(vm => vm.City, new { data_bind = "foo" })

　　

will render this in MVC 3:

<input data-bind="foo" id="City" name="City" type="text" value="" />

　　

If you‘re still using an older version of MVC, you can mimic what MVC 3 is doing by creating this static method that I borrowed from MVC3‘s source code:

public class Foo {
    public static RouteValueDictionary AnonymousObjectToHtmlAttributes(object htmlAttributes) {
        RouteValueDictionary result = new RouteValueDictionary();
        if (htmlAttributes != null) {
            foreach (System.ComponentModel.PropertyDescriptor property in System.ComponentModel.TypeDescriptor.GetProperties(htmlAttributes)) {
                result.Add(property.Name.Replace(‘_‘, ‘-‘), property.GetValue(htmlAttributes));
            }
        }
        return result;
    }
}

And then you can use it like this:

<%: Html.TextBoxFor(vm => vm.City, Foo.AnonymousObjectToHtmlAttributes(new { data_bind = "foo" })) %>

　　

and this will render the correct data-* attribute:

<input data-bind="foo" id="City" name="City" type="text" value="" />

2、枚举绑定

            @Html.DropDownList("sex", new SelectList(Enum.GetValues(typeof(enumSex))), new { @class = "form-control",data_bind="value: Sex"})

                @Html.DropDownListFor(model => model.DepartmentType, new SelectList(Enum.GetValues(typeof(enumDepartmentType))))

 但是上两种方法只有text，没有value，所以有个优化方案如下

public enum Role{
User = 0,
Admin = 1024
}

public class EnumExt{
    static public List<ListItem> ToListItem<T>(){
        List<ListItem> li = new List<ListItem>();
        foreach (int s in Enum.GetValues(typeof(T))){
            li.Add(new ListItem{
                Value = s.ToString(),
                Text = Enum.GetName(typeof (T), s)
            }
            );
        }
        return li;
    }
}

  <%=Html.DropDownList("enumlist") %>

  public ActionResult Index()

{

ViewData["enumlist"] = new SelectList(EnumExt.ToListItem<Role>(),"value","text");

return View();

}

这样我们就可以实现将Enum绑定在DropDownList了
前提还要有一个ListItem类

  public class ListItem
    {
        public string Value { get; set; }
        public string Text { get; set; }
    }

mvc 总结
