I am trying to adapt the AccountController class so that it uses my own backend database. In order to do this completely I need to send a string to the _Layout.cshtml to be checked. How is this possible?
I have tried with ViewData but this requires the Controller to correspond to the view attached eg AccountController to View/Account/LogOn.cshtml will work.
I believe that ViewBag works in the same way as I am getting a null reference when I try to access it in the _Layout.cshtml.
At the moment my code is a bit damaged due to trying to fix the problem but here is what I have. Hopefully it will help to explain better.
AccountController/[HTTP-POST] LogOn
...
if (user.GetRole(model.UserName).Equals("Admin"))
{
ViewBag.Role = "Admin";
}
...
_Layout.cshtml
@if (Request.IsAuthenticated && ViewBag.Role.Equals("Admin"))
{
...
}
I no longer think this can be done with ViewBag or ViewData (Due to comments). Any solution would be welcome.
Thank you in advance - Ankou
Change your code to
if (user.GetRole(model.UserName).Equals("Admin"))
{
ViewBag.Role = "Admin";
}
else{
ViewBag.Role = "";
}
You will get an error of ViewBag.Role
does not exist. So it must always be set.

From your comments, I think you might be best creating a Child Action which has it's own controller and does the work for you.
@Html.RenderAction("LogonDisplay");
This will check the Roles, set the ViewBag values, and then display as needed.
You may be using the _Layout before you call Logon action. Therefore, put a check on your _Layout.
@if (Request.IsAuthenticated && ViewBag.Role != null && ViewBag.Role.Equals("Admin"))
{
...
