I have a textbox receiving input, and I want to both display a single prefix character, but also prevent the user from erasing it in the textbox.  I'm more familiar with win form development, and know how I'd handle it there.
Is that going to be too complicated in asp.net?  I could simply include it myself, stripping it off if it's included, so I didn't want to go for any complex solution.

There are several ways of doing that in ASP.NET but in every case you resort to client-side javascript to intercept key-press events to modify behavior of the control.

Since jQuery is nicely supported by ASP.NET I would recommend to take a look at any "masked input" plugin for jQuery, or even standalone code. Google for "jquery masked input" and check the first few hits - digitalBash has a nice example.

There is a good chance someone has a masked input server-side control for use in WebForms, but you can easily write a UserControl to wrap everything in one reusable unit.

ASP MVC by default has jQuery integrated so adding a plugin shouldnt be a difficult task.

Been a while since I've played with jquery...I'll keep that in the back of my mind.
Thanks for the pointers.
