TabControl tab page requires focus to update?

[Redback]

Im using VS 2005.

I have a form with a tab control. I have text boxes which are bound to a
binding source, which is bound to a dataset.

I have a button on the form that allows the user to add a new record. On
clicking the button, i add a new record to the binding source.

i then wanted to update a number of the textboxes with a default value. At
first I was just using a recursive function to loop through each control and
update the textbox to "0.00". However, I found that only the tabpage that
had focus and the previous page would display the values. That is, If I
selected the second tab, then hit the add new record button, every text box
on the first and second tab would display correctly, however the third would
not. I stepped through the code, the code was assigning a value but it would
not appear.

I have managed to get around the problem by selecting each tab as I update
it, but I was just wondering if I am doing something incorrectly or there is
a better way?

I am using the code below.

thanks

Private Sub SetDefaultValue s()
Try
Me.cboAgreement .SelectedValue = 1

For Each myTabPage As TabPage In Me.TabControl1. TabPages
'For some strange reason, values will not appear unless the
tab
'page is currently selected
TabControl1.Sel ectedTab = myTabPage
SetTextControls ToZero(myTabPag e)
Next
TabControl1.Sel ectedIndex = 0
txtFTFirstHours .Focus()
Catch ex As Exception

End Try
End Sub
Private Sub SetTextControls ToZero(ByVal Page As Control)

Try
For Each ctrl As Control In Page.Controls
Select Case TypeName(ctrl)
Case "TextBox"
If CType(ctrl, TextBox).Name <>
"txtClassificat ionDesc" Then
CType(ctrl, TextBox).Text = "0.00"
End If
Case Else
If ctrl.Controls.C ount 0 Then
SetTextControls ToZero(ctrl)
End If
End Select
Next
Catch ex As Exception

End Try
End Sub
