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.

@{
  // check if we have a url-parameter called "id" with a value - defaults to 0 if not found
  int id = MyPage.Parameters.Int("id");
}
@if (id == 0) {
  @Html.Partial("Coded-List.Typed.cshtml")
} else {
  @Html.Partial("Coded-Details.Typed.cshtml", new { Id = id })
}

Source Code of Coded-Details.Typed.cshtml

@inherits Custom.Hybrid.RazorTyped

  // the ID is already given by the caller, so we just get that
  var id = MyModel.Int("Id");

  // find the person with this Id using LINQ
  var person = AsItems(App.Data.GetStream("Persons"))
    .First(p => p.Id == id);
