Passing objects to layout in mvc 5 - asp.net

Question

I'm passing objects to the Layout from the controller like this:
public ActionResult MyProfile()
{
var roles = new List<int?>();
User.Roles.ForEach(r => roles.Add(r.ID));
return View(new ProfileModel()
{
LoginUser = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(string.IsNullOrEmpty(User.LastName) ? string.Empty : User.LastName.ToLower()),
UserRole = new List<int?>(roles)
});
}
public class ModelBase {
[DisplayFormat(ConvertEmptyStringToNull = false)]
public string LoginUser { get; set; }
public List<int?> UserRole { get; set; }
public ModelBase() {
UserRole = new List<int?>();
}
}
public class ProfileModel : ModelBase { }
This works but, I have to do this for all my Controller Action when returning a view because I need the roles and login user on all my views.
Is there a way for me to do this just once, without having to repeat it in my actions?
I try adding to it to a base controller, but ROLES and LOGINUSER were always null.
I know this has been addressed a lot on SO, but they are all doing the something.
Thanks.

Using Stephen Muecke suggestion I did this:
[ChildActionOnly]
public PartialViewResult Navigation() {
return PartialView("_Navigation", new LayoutModel(User));
}
[ChildActionOnly]
public PartialViewResult LoginInfo() {
return PartialView("_LoginInfo", new LoginInfoModel(User));
}
And
<div class="collapse navbar-collapse" id="navbar-collapse-area">
#Html.Action("LoginInfo", "Home")
</div>
<div class="col-lg-2 sidebox">
<div class="sidebar content-box" style="display: block;">
#Html.Action("Navigation", "Home")
</div>
</div>
Bernard's suggestion also works, but i prefer this.

Try this:
public ActionResult MyProfile()
{
var roles = new List<int?>();
User.Roles.ForEach(r => roles.Add(r.ID));
return View(new ProfileModel(User));
}
Model:
public class ModelBase
{
public ModelBase(User user) {
UserRole = new List<int?>();
LoginUser = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(string.IsNullOrEmpty(user.LastName) ? string.Empty : user.LastName.ToLower()),
}
[DisplayFormat(ConvertEmptyStringToNull = false)]
public string LoginUser { get; set; }
public List<int?> UserRole { get; set; }
}
ProfileModel:
public class ProfileModel : ModelBase
{
public ProfileModel(User user) : base(user) { }
}

I think it is not a bad practice to write some code in your layout. If it is a razor view or something similar you can add user name and its roles directly in the view.
