Binding Tuple Output To The Gridview?

I am developing a web application where in i have a WCF service which interacts with the database using entity framework. I want to get rid of creating Classes for each & every LINQ query
e.g

public class Emp
{
public int CD{get;set;}
public string Name{get;set;}
}
public List<Emp> GetServTypeForPromotionDue()
{
return (from a in Context.TableName
select new Emp{ a.CD, a.NAME });
}

for other table & LINQ i have to create a separate class every time. Alternative to this is to use Anonymous method which is not preferable solution. To avoid both the methods I am using Tuple Class where I return List> or List> depending on the return type. This works fine but the problem is I am binding the result of LINQ query directly to a Gridview By default Tuple has properties item1,item2,..& so on. So my griview shows these names are column names so, Is there any way I can change the property name to CD, Name instead of Tuple's Item1, Item2 before binding to grid?
