Hi all,

I have a latest news section on my site where I wish to implement paging to allow archived/old news items to be accessed. I stumbled upon the following link which I thought would help:

http://our.umbraco.org/forum/developers/razor/41166-Razor-Paging-snippet

However when trying to adapt it and implement it within my code I'm receiving a few strange errors.

The original code in the example states the following:

var pageSize =3;
var page =1;int.TryParse(Request.QueryString["page"],out page);
var items =Model.Content.Children().Where(x => x.IsDocumentType("BlogPost")).OrderByDescending(x => x.CreateDate);

I on the other hand have opted to do this:

var pageSize = 2;
var page = 1; int.TryParse(Request.QueryString["page"], out page);
var latestNews = homepage.latestNews.First();
var items = latestNews.Children().Where(x => x.IsDocumentType("newsItem")).OrderByDescending(x => x.CreateDate);

The problem here is, Visual Studio presents an error on the final line:

Cannot use a lambda expression as an argument to a dynamically dispatched operation without first casting it to a delegate or expression tree type.

As a Javascript developer this is a bit of a wierd error for me and I don't really understand what it means. I think it's something to do with these:

x => x.IsDocumentType("newsItem")
x => x.CreateDate

But to be honest I don't actually understand what these two pieces of code are doing becase I've not seen this type of casting in PHP or any other language I have used.

Any help would be greatly appreciated.
