How do I pass a property from a razor page model to asp-route-id tag helper

So I am using asp.net razor pages and I want to pass a property from one of my page models to be used in the asp-route-id tag helper in the _layout page. I tried injecting the specific page model onto the _layout page and accessing it through @Model tag, when i use this and hover over the nav bar, the route id i want to show comes up, but when i click on it i get this error:

enter image description here

and if I use viewdata, it disappears after clicking on a nav item and becomes null.

_layout.cshtml(shared)

@model VescovererWebApp.Pages.AccountModel

Solution

  • try to use AccountModel as a base class

    public class VescoveredModel : AccountModel

    or you can create interface IAccountModel

    public class AccountModel:IAccountModel

    and

    public class VescoveredModel : IAccountModel

    and change layout model

    @model VescovererWebApp.Pages.IAccountModel
