error - can't create a child list for field ???

[CharlotteR]

ive created a basic form, which loads data from a Customers Table from an Access Database. this works great. when i add buttons such as First, Last, Prev & Next, it all goes a bit mad, with the following message appearing:

An unhandled exception of type 'System.ArgumentException' occurred in system.windows.forms.dll

Additional information: Can't create a child list for field Customers.

my code for these buttons are as follows (i amended them from the Microsoft Visual Basic.Net book):

Private Sub btnFirst_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnFirst.Click
Me.BindingContext(DsCustomers1, "Customers&quot.Position = 0
End Sub

Private Sub btnLast_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLast.Click
Me.BindingContext(DsCustomers1, "Customers&quot.Position = Me.BindingContext(DsCustomers1, "Customers&quot.Count - 1
End Sub

Private Sub btnPrev_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPrev.Click
Me.BindingContext(DsCustomers1, "Customers&quot.Position -= 1
End Sub

Private Sub btnNext_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNext.Click
Me.BindingContext(DsCustomers1, "Customers&quot.Position += 1
End Sub

Thanks for any help,
CharlotteR
