I don't think it can be done via the text box control

However you can define a custom HTML control to take the input

ex:

<input type="text" onpaste="return false;" />

Hi Rakesh

Why are you attempting to block copy & paste? It may not be a good idea.

I just did a google search and ran into the following posts. 

This post talks about doing it for Windows as a whole. I don't think that is what you are attempting to do. But, if you were really doing for security reasons, you may want to look at this post.

This post talks about approaches already tried. You can take a look to know why those didn't work

This post talks about using javascript /jquery. It appears the previous person has given something along the same lines and it isn't clear whether or not you tried it.
