Ispostback occurs only when the page_loads on first time suppose if you want to access the some code on each postback write it on else part ie: when the postback is false .

Hi,

This is because a refresh is different to a postback. If you refresh the page IsPostBack will always be false, because as far as ASP.NET is concerned, the page is loading for the first time. If you want to implement this functionality, a better solution might be to use an AJAX Timer. You can add a timer to your page, and configure its interval to 30 seconds- it will then force an async postback on each timer tick and IsPostBack will equal true.
