Use AddHandler to add the common lostfocus event handler to all of your
textboxes.

Private Sub txtBoxLostFocusHandler(ByVal sender As Object, _
       ByVal e As System.EventArgs)

End Sub

AddHandler TextBox1.LostFocus, AddressOf txtBoxLostFocusHandler
AddHandler TextBox2.LostFocus, AddressOf txtBoxLostFocusHandler
...
...

Also, if you are using the same lost focus event handler for all of the
textboxes on your form (or some other container such as a panel, tab page,
etc), you can do this within a loop:

' replace Me with whatever container you have your controls on
For Each txtBox As TextBox In Me.Controls
   AddHandler txtBox.LostFocus, AddressOf txtBoxLostFocusHandler
Next txtBox

hope that helps..

Ooops...  I misread your question.  'AddHandler'/'RemoveHandler' are the way
to go...

Thanks to Iram and Herfried !
