Question

I need some guidance with an issue, I am using Entity Framework 4.0, I have a DAL and BLL and am binding to ObjectDataSource on the page.

I had to write a stored pr

Answer 1

If you already have an Entity type that matches your proc return type, use it as the type parameter.

public List GetData(int product_id) where T : class 
{

    List myList = new List(); 

    var groupData = context.ExecuteStoreQuery("exec 
    spGetProductsByGroup @ProductID={0}", product_id);

    return myList;
}

Otherwise you could use an ADO.NET DataReader to build the list manually.

using (SqlConnection connection = new SqlConnection("your connection string"))
{
    SqlCommand command = new SqlCommand(
      "exec spGetProductsByGroup @ProductID",
      connection);
    command.Parameters.Add(product_id);

    connection.Open();

    SqlDataReader reader = command.ExecuteReader();

    List list = new List();
    if (reader.HasRows)
    {
        while (reader.Read())
        {
            list.Add(new ProcType(){Property1 = reader.GetInt32(0), Property1 = reader.GetString(1));
        }
    }
    reader.Close();

    return list;
}
