Hi friends,
How do find server control on client side?
I tried using "document.getElementById('btnBack').value;" but this gives me the text property of the button.
I want to find the id of that button inorder to enable/disable it.

Could you please tell me how do we do that?

Regards,
Lok..

Nice and simple

This may not work when you are used Update Panel because it will automatically rename with e.g. ctl00_btnBack

I agree, it will not. But based on what OP was trying it would. :)
