sorry didnt see the all your questions

where do I set the btnSave.enabled = true ?
in the event handler
in case your using dynamic_sysop sample it would look like this
Code:
Private Sub txtBox_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtBox.TextChanged
    btnSave.Enabled=True
    End Sub



in each txtbox change event? doesn't that defeat the purpose of creating a handler?
didnt really understand what your asking, but here you just have 1 handler for all the text boxes
