I have to create a GridView from a List<>

I have to create a GridView from a List that hold data from an SQL Server table. The. A web service is being using by I think LINQ, and is added to a List<>. This is the code I have so far in the EmployeeManager. How can I populate my GridView with this List<> data. The page load is from EmployeeManager.aspx.cs and my GridView is in EmployeeManager.aspx
I need help like yesterday, thanks

EmployeesAdmin.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace Psc.Employees.EAdmin
{
    public class EmployeesAdmin
    {
       private Admin.iAdmin _ws;

       public List<Admin.vwEmployees> GetEmployees(out string x, int i, bool blDisabled)
       {
           return _ws.GetEmployees(out x, i, blDisabled);
       }
    }
}
