Is it possible to take an ASP textbox that has an attribute of
visible='hidden' and make it visible from javascript? I dont want it
to be visible until data on the page has been entered and thus need a
way to dynamically change its visibility?

Thanks in advance

Yes, you can either fiddle with the object's style.visibility, or assign
it a CSS class with the appropriate style settings.

What you call an "ASP textbox" represents no more than an HTML form
control that is generated by server-side ASP.NET code (.NET due to
your mentioning of C#). Probably that server-side code results in
something along

<input ... style="visibility:hidden" />

So if, and only if, client-side script support and sufficient DOM Style
support is available, you can make that control visible again (without
reloading the document):

referenceToControl.style.visibility = "visible";

or standards compliant (W3C DOM Level 2 Style):

referenceToControl.style.setProperty("visibility", "hidden", "");
