Hi Abdalla,

You need to manage role name properly in your database. Like assigning the Admin role to Ben and the User role to User1. Now only you need to attach the role name with your AdminRoleView.Users data. It will display proper role with users in the gird section.

Also, there are multiple ways to handle a role properly. As you can manage roles with another role table in db. And assign a role id to the user. Also, you can manage parent and child role concept using it.

For example :

RoleTable :

Id Name ParentRoleId

1 Admin Null

2 User 1

UserTable :

ID Username RoleId

1 Ben 1

2 User1 2

There are multiple ways to perform roles, roles& rights. Above is a basic and simplest way to perform roles with users. By using the above technique, you will be able to display role in a nested view under your gird. Like all users, list under admin.

Happy Coding...!!!

Please share your backend code (controller code).

This means your Model is incorrectly designed.
It should be
public class User
{
public int UserId{get;set;}
public string Name{get;set;}
public string Email{get;set;}
public Role Role{get;set;}
}
public class Role
{
public int RoleId{get;set;}
public string RoleName{get;set;}
}
// controller
public List GetUsers()
{
List Roles= new List()
{
new Role(){RoleId=1,RoleName="Admin"},
new Role(){RoleId=2,RoleName="User"},
}
List users= new List()
{
new User(){UserId=1,Name="Ben",Email="[email protected]",Role=Roles[0]},
new User(){UserId=2,Name="Ben",Email="[email protected]",Role=Roles[1]}
}
return users;
}
public IActionResult Index()
{
return view(GetUsers());
}
// view
@model IEnumerable









@foreach(var user in Model)
{





}

Name Email Role
@user.Name @user.Email @user.Role.Name

Id	Name	ParentRoleId
1	Admin	Null

ID	Username	RoleId
