What is strongly-typed View in ASP.NET MVC?

question from:https://stackoverflow.com/questions/2896544/what-is-strongly-typed-view-in-asp-net-mvc

Answer 1

It is an aspx page that derives from System.Web.Mvc.ViewPage<TModel>. It is said that this view is strongly typed to the type TModel. As a consequence to this there's a Model property inside this view which is of type TModel and allows you to directly access properties of the model like this:

<%= Model.Name %>
<%= Model.Age %>

where as if your aspx page derived from System.Web.Mvc.ViewPage you would need to pull values from ViewData the view no longer knows about the TModel type:

<%= (string)ViewData["Name"] %>
<%= (int)ViewData["Age"] %>

or even worse:

<%= ((SomeModelType)ViewData["model"]).Name %>

and there's no compile time safety in such code.

Notice also that there's the ViewUserControl<TModel> counterpart for strongly typed partials (ASCX).
