Data persistence and updates in ASP.NET Web Forms
<p>I'm currently working on a web app/game using C# and ASP.NET(3.5). However, I'm running into a problem of variables used in the main page being reset to null whenever I click a button on the web form. I'm wondering if there was a way to allow to variables to persist for the life cycle of the entire application, as well as for the variables to be accessed from wherever/whenever.</p>

<p>Another issue I'm having at the moment is that I can't seem to find a way to update the properties of controls, like text or colour, without having to refresh the page. Is there a way to update these properties "silently" without forcing the user to go through the whole page refresh cycle?</p>

<p>Thanks</p>
