DataTable or BindingSource?? C# Question

I am using C# Windows Forms and dealing with databases and recordsets. I am finding that I have code that works the same using a bindingsource and datatable. You can see the code I have attached. Previously my code utilized the datatable, then as a test I modified a couple of lines of code to use the bindingsource instead and found that it works as well.

Can someone tell me the difference between these 2 items and which is better to use?

SqlConnection cn = new SqlConnection(PubVar.dbConn);

                SqlCommand cmd = new SqlCommand(PubVar.dbConn, cn);
                cmd.CommandText = "sp_LookupPrices";
                cmd.CommandType = CommandType.StoredProcedure;

                SqlParameter param;
                param = cmd.Parameters.AddWithValue("@CustomerNumber", txtCustomerNumber.Text);
                param = cmd.Parameters.AddWithValue("@CustomerName", txtCustomerName.Text);
                param = cmd.Parameters.AddWithValue("@ProductNumber", txtProductNumber.Text);
                param = cmd.Parameters.AddWithValue("@ProductName", txtProductName.Text);
                param = cmd.Parameters.AddWithValue("@CompanyID", PubVar.CompanyID);
              //---OLD 1 line of code using the datatable
               // DataTable tbl = new DataTable();

                SqlDataReader rdr = cmd.ExecuteReader();

             //--OLD 2 lines of code using the datatable
               // tbl.Load(rdr);
                //dgPriceSearch.DataSource = tbl;

              //---new 2 lines of code using the bindingsource
                BindingSource bs1 = new BindingSource(rdr, null);
                dgPriceSearch.DataSource = bs1;

          catch (Exception ex)

if data that u are getting from db can possibly change, then use binding source other wise it is better to use datatable

As far as I know using BindingSource is quicker than using a DataTable because it binds directly to the datasource, where if you use a datatable you bind, then have to read the data and then load it.
BindingSource also provides a bit more functionality to data manipulation like currency management and change notification.

BindingSource is definately the way to go.
