I want to change site theme dynamically. I used this link that shows how to do that. my question is here that in query string you can redirect from page to another web-form to use the query string. this works good for one page and change the theme of second page correctly.
but I want to apply the new theme to all the web-forms that I have.
I know, It's like user log-In (it's user session), but because we used a package for user login I don't know how to use a good session or query string to apply my new theme...
if it helps: it's asp.net 4.5 and we used Microsoft.AspNet.Identity package for login User.
