populating combo thro' ado.net thro' coding

Hello Everybody!!
Well, I have to populate a combobox from an access database.
I can do it using server explorer.and it is working fine.
But when i do it with coding (ie creating connection,connstring,command etc),when i set Data source and Display name preoperty of combo in coding it gives me an error saying
'COMPLEX DATA BINDING ACCEPTS AS A DATASOURCE EITHER AN ILIST OR ILISTSOURCE'
(The same 2 properties r to be set while using server explorer as well.)
Can anyone tell me what does this mean and what should i do abt it?
Luv
Amita

Try this

VB Code:

Private Sub PopulateCustCombo()
        Dim myconn As New SqlConnection(CON_STRING)
        Dim dsCust As New DataSet()
        Dim mysqladapter As New SqlDataAdapter()
        myconn.Open()
        mysqladapter = New SqlDataAdapter("SELECT CustomerID, ContactName FROM Customers", myconn)
        mysqladapter.Fill(dsCust, "customer")
        With cboCustomerID
            .DataSource = dsCust.Tables("customer")
            .DisplayMember = "CustomerID"
        End With
        myconn.Close()
    End Sub
