You can set the variable in code behind, but using code behind to decrement the variable would be impractical since it would require a postback every second. Your best bet is to do the decrementing on the client side with javascript.

Hello Experts,<br />
<br />
I have an aspx page that I want upon clicking on a button, from code behind I assign a certain number of minutes to a timer on the page.<br />
<br />
The time should be displayed on a label in the page with a countdown.<br />
<br />
For example, if my code behind variable holds the value of &quot;5&quot;, clicking the button will make the label.text = 5, then it should work like a stopwatch (4:59 etc..) until 0:00<br />
<br />
Is that possible?

ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.

Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services using a wide variety of languages and standards, including the familiar HTML, JavaScript and jQuery, ASP and ASP.NET, PHP, ColdFusion, CSS, PHP, Flex and Flash, but also the implementation of a broad list of standards including XML, WSDL, SSDL, VoiceXML and many more.
