Binding Linq Query to Drop Down List

Hi,

Hi,

New to EF.  I'm trying to bind the results of a linq query to a drop down list.  Here's the code:

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

namespace ABC
{
    
    public partial class createDoc : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            HCLEntities Context = new HCLEntities();

            var query = from p in Context.Equipments
                                             orderby p.Unit
                                             select p.Unit;

            projectDropDownList.DataSource = query;
            projectDropDownList.DataBind();

        }
    }
}

Select allOpen in new window

When the code is executed, I get the following message:
Data binding directly to a store query is not supported. Instead populate a DBSet with data, for example by calling Load on the DBSet, and then bind to local data.

Not sure how to fix the error.  Suggestions would be greatly appreciated.
