Remove Assigned Users From Role In ASP.NET MVC

• Assigning Role To User In ASP.NET MVC Membership

In previous tutorial swe learned how to assign role to users, here we will learn how to remove Role from assigned user. For this purpose we need to add a action method in account controller class. In previous tutorials we created a model class name is “AllroleWithAllUser” . we will use the same class here to pass this class in controller.

Following code is for “RemoveRoleForUser” in controller class.

After creating action method for [HttpGet], now we need to add another action method for the [httpPost] . So the following is code for the “RemoveRoleForUser” action method for[httpPost] method.

1. [HttpPost]
2. [ValidateAntiForgeryToken]
3. public ActionResult RemoveRoleAddedToUser(AssignRole _assignRole)
4. {
5. if (_assignRole.UserRoleName == "0")
6. {
7. ModelState.AddModelError("RoleName", "select proper RoleName");
8. }
9. if (_assignRole.UserID == "0")
10. {
11. ModelState.AddModelError("UserName", "select proper Username");
12. }
13. if (ModelState.IsValid)
14. {
15. int currentUserId = CheckUserWithUserRole(Convert.ToInt32(_assignRole.UserID));
16. if (currentUserId == Convert.ToInt16(_assignRole.UserRoleName)) {
17. var UserName = GetUserName_BY_UserID(Convert.ToInt32(_assignRole.UserID));
18. var UserRoleName = GetRoleNameByRoleID(Convert.ToInt32(_assignRole.UserRoleName));
19. Roles.RemoveUserFromRole(UserName, UserRoleName);
20. ViewBag.ResultMessage = "User Role is removed successfully !";
21. } else {
22. ViewBag.ResultMessage = "This current user doesn't belong to selected user role.";
23. }
24. _assignRole.UserRolesList = GetAll_UserRoles();
25. _assignRole.Userlist = GetAll_Users();
26. } else {
27. _assignRole.UserRolesList = GetAll_UserRoles();
28. _assignRole.Userlist = GetAll_Users();
29. }
30. return View(_assignRole);
31. }

Following is the code for removing the role for the respective user. Following is the code for checking that selected user belongs to the respective RolId.

1. public int CheckUserWithUserRole(int UserId)
2. {
3. using(UsersRoleContext context = new UsersRoleContext())
4. {
5. int RoleId = context.webpages_UsersInRole.Where(c => c.UserId == UserId).Select(c => c.RoleId).SingleOrDefault();
6. return RoleId;
7. }
8. }

Now right click on the” RemoveRoleAddedToUser” controller and add the view to this controller, this view contains the scaffold template as “Create” model class and model class as “assignRole”.
