In the aspx page I am calling the the user control two times. On page load 1 usercontrol will be visible but the the other will be visible on button click and it should show only book description and book title. To achieve this I named the class of the whole coloumn as hide. Now in when aspx page if I execute:

   $('#continue').click(function () {
        $(".hide").hide()
    });
It removes the coloumn from both the usercontrol called in the aspx as both share the same structure. So can anyone help me how can hide the 3rd coloumn from aspx of the 2nd usercontrol.
I want to get this as output when I click on the button the lower portion is should be visible without the checkbox column


But I am getting this as output here from both the tables the checkbox is removed


What I have tried:
