How to solve Windows security window prompt for authorization failed in ASP.NET MVC

Question

My questions:

1. When a user doesn't have Manager role and Admin role, I have to redirect to an error page/some popup message. But when the user is not authorized, the Windows security password prompt continuously keeps showing. When I enter the user name and password again, it's showing Windows security password.

2. Every action method I have to check and I need to show the message or error page.

How do I solve this issue?

Controller code:

[AuthorizeUser("Manager","Admin")]
public ActionResult Contact()
{
    return View();      
}

C# code:

public AuthorizeUserAttribute(params int[] roles)
{
    allowedroles = roles;
}

protected override bool AuthorizeCore(HttpContextBase httpContext)
{
    bool authorize = false;
    var getList = _objService.GetUserRoleDetail(CommonStaticHelper.getLoggedUser());

    foreach (var role in allowedroles)
    {
        if (getList.Exists(m => m.RoleId == role))
        {
            return authorize = true; /* return true if Entity has current user(active) with specific role */
        }
    }

    return authorize;
}

protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
{
    filterContext.Result = new HttpUnauthorizedResult();
}

Try this :

// Create an action :
public ActionResult Unauthorized()
{
    return View();
}

// now write below code for authorization:

protected override void HandleUnauthorizedRequest(System.Web.Mvc.AuthorizationContext filterContext)
{
    if (filterContext.HttpContext.Request.IsAuthenticated)
    {
        // redirect to the Unauthenticated page
        filterContext.Result = new RedirectToRouteResult(new
            RouteValueDictionary(new { controller = "Error", action = "Unauthorized" })
        );
    }
    else
    {
        base.HandleUnauthorizedRequest(filterContext);
    }
}

protected override bool AuthorizeCore(HttpContextBase httpContext)
{
    var authorized = base.AuthorizeCore(httpContext);

    if (!authorized)
    {
        // The user is not authenticated
        return false;
    }
   else
   {
        var getList = _objService.GetUserRoleDetail(CommonStaticHelper.getLoggedUser());

        foreach (var role in allowedroles)
        {
            if (getList.Exists(m => m.RoleId == role))
            {
                // return true if Entity has current
                // user(active) with specific role
                return authorize = true;
            }
        }

        return authorize = false;
    }
}
