Assigning Role to User in Asp.Net MVC Membership

Before proceeding to this tutorial please go to Display Roles for the users in Asp.Net MVC Membership
Here we will learn how to How to assign roles to the users in asp.net membership provider. For assigning the roles to the user we need to add a model for member list and roles List.

1^st add a model class in account model.cs class name is “AssignRolesToUsers”.

public class AssignRole     {         [Required(ErrorMessage = " Select proper UserRole Name")]         public string UserRoleName { get; set; }         [Required(ErrorMessage = "Select UserName")]         public string UserID { get; set; }         public List<SelectListItem> Userlist { get; set; }         public List<SelectListItem> UserRolesList { get; set; }     }

After creating the model we need to add a action method in controller class name is “AssignRolesToUsers”.

[HttpGet]         public ActionResult AssignRolesToUsers()         {                     }

Now add a DbSet to the UserProfile class

public class UsersRoleContext : DbContext     {         public UsersRoleContext()             : base("DBConnectionForMembership")         {         }         public DbSet<Role> UserRoles { get; set; }         public DbSet< UserProfile > UserProfile { get; set; }     }

Now create two nonAction method got getAllUsers and GetAllUserRoles in Account Controller.

So for that write the following code

[NonAction]         public List<SelectListItem> GetAll_UserRoles()         {             List<SelectListItem> listrole = new List<SelectListItem>();             listrole.Add(new SelectListItem { Text = "select", Value = "0" });             using (UsersRoleContext db = new UsersRoleContext())             {                                foreach (var item in db.UserRoles)                 {                     listrole.Add(new SelectListItem { Text = item.RoleName, Value = Convert.ToString( item.RoleId) });                 }             }             return listrole;         }         [NonAction]         public List<SelectListItem> GetAll_Users()         {             List<SelectListItem> listuser = new List<SelectListItem>();             listuser.Add(new SelectListItem { Text = "Select", Value = "0" });             using (UsersRoleContext db = new UsersRoleContext())             {                 foreach (var item in db.UserProfile)                 {                     listuser.Add(new SelectListItem { Text = item.UserName, Value = Convert.ToString(item.UserId) });                 }             }             return listuser;         }

Now add the following code to the “AssignRolesToUsers” action method

[HttpGet]         public ActionResult AssignRolesToUsers()         {             AssignRole _addignroles = new AssignRole();             _addignroles.UserRolesList = GetAll_UserRoles();             _addignroles.Userlist = GetAll_Users();             return View(_addignroles);         }

Now after assign the object value need to add view for this action method so for that right click on this action method and select strongly typed model as “AssignRoles” and scaffold template as create.

After click on add it will generate some code for us nut we need to make changes in this view

@model MvcMembershipProvider.Models.AssignRole @{     ViewBag.Title = "AssignRolesToUsers"; } <h2>AssignRolesToUsers</h2> <link href="~/bootstrap/css/bootstrap.min.css" rel="stylesheet" /> <script src="~/bootstrap/js/bootstrap.min.js"></script> @using (Html.BeginForm()) {     @Html.AntiForgeryToken()     @Html.ValidationSummary(true)     <fieldset>         <legend>AssignRole</legend>         <div class="editor-label">             @Html.LabelFor(model => model.UserRoleName)         </div>         <div class="editor-field">             @*@Html.EditorFor(model => model.UserRoleName)*@             @Html.DropDownListFor(m => m.UserRoleName, new SelectList(Model.UserRolesList, "Value", "Text"), new { style = "width:200px", @class = "form-control" })             @Html.ValidationMessageFor(model => model.UserRoleName)         </div>         <div class="editor-label">             @Html.LabelFor(model => model.UserID)         </div>         <div class="editor-field">             @*@Html.EditorFor(model => model.UserID)*@             @Html.DropDownListFor(m => m.UserID, new SelectList(Model.Userlist, "Value", "Text"), new { style = "width:200px", @class = "form-control" })             @Html.ValidationMessageFor(model => model.UserID)         </div>         <p>             <input type="submit" value="Create" />         </p>     </fieldset> } <div>     @Html.ActionLink("Back to List", "Index") </div> @section Scripts {     @Scripts.Render("~/bundles/jqueryval") }

Now run your application and go to following url then o/p will look like this

http://localhost:50526/Account/AssignRolesToUsers

Add role to the user

Now here we will create action method to add the role to the users with the post method.

Write the following code in Post action method for the “AssignRolesToUsers”.

[HttpPost]         [ValidateAntiForgeryToken]         public ActionResult AssignRolesToUsers(AssignRole _assignRole)         {             if (_assignRole.UserRoleName == "0")             {                 ModelState.AddModelError("RoleName", " select UserRoleName");             }             if (_assignRole.UserID == "0")             {                 ModelState.AddModelError("UserName", " select Username");             }             if (ModelState.IsValid)             {                 if (Get_CheckUserRoles(Convert.ToInt32(_assignRole.UserID)) == true)                 {                     ViewBag.ResultMessage = "Current user is already has the role";                 }                 else                 {                     var UserName = GetUserName_BY_UserID(Convert.ToInt32(_assignRole.UserID));                     var UserRoleName = GetRoleNameByRoleID(Convert.ToInt32(_assignRole.UserRoleName));                     Roles.AddUserToRole(UserName, UserRoleName);                     ViewBag.ResultMessage = "Username added to role successfully !";                 }                 _assignRole.UserRolesList = GetAll_UserRoles();                 _assignRole.Userlist = GetAll_Users();                 return View(_assignRole);             }             else             {                 _assignRole.UserRolesList = GetAll_UserRoles();                 _assignRole.Userlist = GetAll_Users();             }             return View(_assignRole);         }

Following code for get  UserName by using userid

public string GetUserName_BY_UserID(int UserId)         {             using (UsersRoleContext context = new UsersRoleContext())             {                 var UserName = (from UP in context.UserProfile                                 where UP.UserId == UserId                                 select UP.UserName).SingleOrDefault();                 return UserName;             }         }

Following code for get  UserRoleName by using userRoleId

public string GetRoleNameByRoleID(int RoleId)         {             using (UsersRoleContext context = new UsersRoleContext())             {                 var roleName = (from UP in context.UserRoles                                 where UP.RoleId == RoleId                                 select UP.RoleName).SingleOrDefault();                 return roleName;             }         }

Following code for checking that current user have role name or not

public bool Get_CheckUserRoles(int UserId)         {             using (UsersRoleContext context = new UsersRoleContext())             {                 var data = (from WR in context.webpages_UsersInRole                             join R in context.UserRoles on WR.RoleId equals R.RoleId                             where WR.UserId == UserId                             orderby R.RoleId                             select new                             {                                 WR.UserId                             }).Count();                 if (data > 0)                 {                     return true;                 }                 else                 {                     return false;                 }             }         }

Now run your application and go to the following URL and check the entries

http://localhost:50526/Account/AssignRolesToUsers

database table is

Create a view with all roles and all the users

First for this add a model in account.cs class under model folder. So code for this is

public class AllroleWithAllUser     {         public string UserRoleName { get; set; }         public string UserName { get; set; }         public IEnumerable<AllroleWithAllUser> AllDetailsUserlist { get; set; }     }

Write a nonAction method in controller to get all user with respective UserRole

[NonAction]         public List<AllroleWithAllUser> GetUserNameResepectiveToRole()         {             using (UsersRoleContext db = new UsersRoleContext())             {                 var Alldata = (from User in db.UserProfile                                join WU in db.webpages_UsersInRole on User.UserId equals WU.UserId                                join WR in db.UserRoles on WU.RoleId equals WR.RoleId                                select new AllroleWithAllUser { UserName = User.UserName, UserRoleName = WR.RoleName }).ToList();                 return Alldata;             }         }

Now write a action method for getting this

[HttpGet]         public ActionResult DisplayAllUserroles()         {             AllroleWithAllUser _alluserWithRole = new AllroleWithAllUser();             _alluserWithRole.AllDetailsUserlist = GetUserNameResepectiveToRole();             return View(_alluserWithRole);         }

Now we need to add a view for showing  All user with their respective Role. So right click on action method and add a view with scaffold template as empty.

And the write following code in the view

@model MvcMembershipProvider.Models.AllroleWithAllUser @using GridMvc.Html @{     ViewBag.Title = "DisplayAllUserroles"; } <h2>DisplayAllUserroles</h2> <link href="~/Content/Gridmvc.css" rel="stylesheet" /> <link href="~/bootstrap/css/bootstrap.min.css" rel="stylesheet" /> <script src="~/Scripts/jquery-1.9.1.min.js"></script> <script src="~/Scripts/gridmvc.js"></script> @Html.Grid(Model.AllDetailsUserlist).Columns(columns => {     columns.Add(c => c.UserName).Titled("UserName").Filterable(true).SetWidth(300);     columns.Add(c => c.UserRoleName).Titled("RoleName").Filterable(true).SetWidth(300); }).WithPaging(10).Sortable(true)

Now run your application and go to following URL

http://localhost:50526/Account/DisplayRoleForUsers
