Clearing a login button

Question

What code do we use when we are trying to make a login button disappear from your web form after you've logged in? In c#?

Answer 1

C# isn't usually used to create web pages. You would usually use HTML and JavaScript.

Answer 2

I guess I worded my question incorrectly. I am creating a web page in ASP.Net using HTML I put C# because I thought in addition to putting something in the HTML that there could be some code behind it in C# to get it to work.
