The data source does not support server-side data paging

Question

I have a GridView on my screen and need it to allow paging.

Markup:

Answer 1

I've changed my code to this:

public List<string> ListofNewsTitle()
{
    var query = from n in db.NewsEvents
                orderby n.NewsDate descending
                select n.NewsTitle;
    return query.ToList();        
}

Answer 2

A simple ToList() on your result var should work.

Edit: As explained in comments below my answer, the reason for the error is that the data source should implement ICollection. IEnumerable does not, when you do ToList() it converts it into a list which implements ICollection.
