我是新來的MVC添加更新，並與MVC3和RAZOR
我使用實體框架相同的視圖中刪除。
我有三個數據庫表這些都是
User: UserID,UserName
Role: RoleID,RoleName
UserRoles: ID,UserID,RoleID
UserDataModel.cs
[MetadataTypeAttribute(typeof(UserMetaData))]
public partial class User
{
[Required(ErrorMessage = "Please enter your again")]
[DataType(DataType.Password)]
[Compare("Password")]
public String ConfirmPassword { get; set; }
}
public class UserMetaData
{
[Required(AllowEmptyStrings = false, ErrorMessage = "You forgot to enter your name.")]
[Display(Name = "Your Name")]
[StringLength(50, MinimumLength = 3, ErrorMessage = "Your name is too long. Please change your name if you can !")]
public String UserName { get; set; }
[Required(ErrorMessage = "Do you know your gender ?? if you don't know, leave it !!")]
public Boolean Gender { get; set; }
[Required(ErrorMessage = "You forgot to select your current country.")]
public Int32 CountryID { get; set; }
[Required(ErrorMessage = "Please tell us your 'Happy birth date'. We may brings you a huge gift for you on your birthday.")]

Please enter date in dd/MM/yyy formate")]
public DateTime DOB { get; set; }
[Required(ErrorMessage = "Please tell us your email address. we assure you that we can't reach you with your email address.")]
[RegularExpression("\\w+([-+.]\\w+)*@\\w+([-.]\\w+)*\\.\\w+([-.]\\w+)*", ErrorMessage = "Oh Noo!! Please enter date in dd/MM/yyy formate")]

它的做工精細！當我點擊編輯除用戶角色複選框以外的所有數據。
其實我在「UserRoles」中有角色列表。
如何在編輯模式下獲取用戶角色列表???????
請幫我一把。如果我做錯了什麼，請讓我知道。
你用什麼模型爲RegisterUser.cshtml（）。通常你會使用@ Html.CheckBoxFor（model => model.SomeProperty）。 – acarlon
請看看更新的問題...... –
其實我使用foreach循環綁定了我的「MasterRole」複選框列表，而我的視圖是強類型的「用戶」。 –
