The model item passed into the dictionary is of type... but this dictionary requires a model item of type

I've got an MVC project with a Layout that has strongly typed model named "Dashboard".

@model Dashboard_v2.Models.Dashboard

This Layout has a RenderBody() method that renders the rest of the pages.

then, on my main page, I have a View that is strongly typed with the Model NewPatient.

on the controller I have bunch of code, and eventually I pass a NewPatient Model to it.

When I try to run this code, I've got an error called : 

The model item passed into the dictionary is of type 'Dashboard_v2.Models.NewPatient', but this dictionary requires a model item of type 'Dashboard_v2.Models.Dashboard'.

why does it expects a Dashboard Model, if my page has strongly typed NewPatient Model?

Why do you need a Model on a layout View anyway? – melancia
Remove the model definition from the layout. The model needs to be defined in the view (you are telling every view that its model must be Dashboard) – user3559349
Optionally (i.e. it's a must), read this. – Andrei V
ohh.. I see.. Thanks! – thormayer
If your wanting to render some details relating to Dashboard in all views, then in the layout use @Html.Action() to call a child action method that returns a partial view based on an instance Dashboard – user3559349

One approach is to define a Viewmodel with generic parameter MainViewModel<T>and instance it with appreciated T for the views. Then you can use the MainVewModel properties in Layout and use properties of T in your views.
