I am currently working with onlize quiz. Is it possible to disable CTRL, ALT, other keys and status bar? My concern is to secure my page such that nobody can copy any data displayed in the page.
How can I do this in ASP.Net using C# as my script?

You do not have the right to take over the user's computer. It is illegal to do so.

This will only happen when my students will conduct online quiz using my site. After they have logged in to my site and opening the page for online quiz that's the only page where those keys should be disabled to ensure that when they conduct the quiz they will not copy the questions and give it to my other students who were not able to take yet their online quiz.
I think this objective is good. If you dont want to share the code to anybody else they might use it for bad things, please email to me the answer at <snipped>. You may visit my site to prove that I am using it in my class <snipped>

Yes you can disable those keys, but it won't stop them from using the clipboard.
However, what you can do is set up a javascript function that gets called constantly. Then inside the function you set a cursor position, which will stop them from highlighting, and from "Selecting All".

That will go completely against HCI (Human-Computer Interaction) as you make site difficult to read and just get students something silly to complain about...
