Linq to SQL

Question

I am using entity framework and Linq to fetch the data.

 

I have to tables Product and Order Detail. In Order detail table I have order Id and Product Id. While displaying data in gridview  I am fetching data from order detail table. But I don't want to show Product Id in the grid. Instead of that I want to show related product name from product table.

 

I have EDMX file which has created two classes Product and Order detail. I am using LINQ to fetch data from Order details table. How can I get Product Name of related product ID. Method return type can not be Order detail. It gives me below error.

 

 Cannot implicitly convert type 'System.Linq.IQueryable<AnonymousType#1>' to 'System.Collections.Generic.List<OrderDetail>
