I have a textbox, and when I type in it, I would like it to add a dash after every 4 characters. Like, 3818-2320-1232.
I tried some code that someone posted on another thread, but it adds a dash, literally after every four characters; Like, 3818-2320-1232- (the last dash shouldn't be there). how should i go about this?
