Basic List Details using Code - with separate Details-File
Very often you have a list of items, and then a details-page showing just one item. In this example, we'll just use code to do this (so no visual query) - just so you understand the principle. This example splits the list/details templates into 3 files, which is easier to manage. File 1 choses what should happen, file 2 contains the list, and file 3 the details.

@if (MyPage.Parameters.IsEmpty("id")) {
@Html.Partial("Coded-List.Strong.cshtml")
} else {
@Html.Partial("Coded-Details.Strong.cshtml", new { Id = MyPage.Parameters.Int("id") })
}
