The following code is the code behind of a blank page (With a scriptmanager)
on which I'm trying to simulate a problem I'm having elsewhere in a larger
app.
The app is supposed, in this case, to dynamically create a textbox and a
MaskEditExtende r and associate the 2 together.
I'm obviously doing something wrong as I'm getting a exception.
