setting text value of a bound textfield

[mjw]

I am new to VB.Net 2005 and would like to thank anybody in advance who
may help me out.
In my windows form application I am using a BindingNavagator tool strip

to display values of my database fields which are bound to my
tablesBindingSource. This works fine. What I need to do when I select
the new data row entry from the tool strip is pass one of the fields a
text field value from another TextBox on the page. I cannot get this to

work. My code always shows blank. I also thought I might have to set
the value to the bindingSource
but can't figue out a way of doing it.
Private Sub bindingNavigatorAddNewItem1_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs) Handles
bindingNavigatorAddNewItem1.Click
PassFamilyId()
End Sub
Private Sub PassFamilyId()
Me.FamilyIDTextBox1.Text = FamilyIdTextBox.Text
End Sub
Thanks Mike
