Actually it seems to be easier than that to do. I opened the .cdxml
file for my test app and changed the line <dTextBox... to
<dMaskedTextBox.. After saving it and opening the CD it showed in the
Properties sheet as a dMaskedTextBox. I was able to give it a RegId and
change the border spacing. It respected changes I made using Edit Sizer
Settings control. Down in the EditCode section it showed up but had no
methods. I clicked on the New button and added the method:
def afterInit(self):
self.setProperties({"Mask":"A{2} - #{3}"})
I saved it and ran the form and it worked just like I expected a
dMaskedTextBox to work. It displayed a textbox with a - in it. To the
left of the - it would accept only 2 uppercase letters and 3 numbers to
the right. I printed its value and got the 2 letters and 3 numbers with
no - . To be sure I shutdown the CD and ran it from the cmdline and it
still worked as expected.
So from this limited testing is seems you can without too much trouble
use a dMaskedTextBox in the CD. I'm going to backup a project I am
working on and try to replace a normal textbox with a masked one and see
if it still works.
