Question : using button to navigate textboxes

vb.net 2008

What I have:
I have 72 textboxes on a form.
textbox0 to textbox71

9 across
8 down

For now I need a button to go to the "right" --->

Problem:
This is working until I get to the "texbox2" then stops

In the Gotfocus event of each textbox I have:
Private Sub TextBox0_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox0.GotFocus
MyName()
End Sub
Private Sub TextBox1_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.GotFocus
MyName()
End Sub

Private Sub TextBox2_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox2.GotFocus
MyName()
End Sub

Private Sub TextBox3_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox3.GotFocus
MyName()
End Sub

Public currentLocation As Integer

Public Function MyName()
On Error Resume Next
Dim myPointer As Integer
Dim ctlCurrentControl As TextBox
ctlCurrentControl = ActiveControl
myPointer = Mid(ctlCurrentControl.Name, 8)

End Function

Any suggestions ?
Thanks

Answer : using button to navigate textboxes

Here's an example of how to "wire up" ALL 72 TextBoxes to the same event handler at run-time so you don't have to manually create 72 different handlers in the IDE.

Also included are examples of how to implement Left, Right, Up and Down buttons:
