# What is Ispostback method in ASP.Net? Why do we use that?

Basically Post back is an action performed by a interactive Webpage. When it goes to the server side for a non-client Operation Server again posts it back to the client and hence the name.\
**Ex:**\
if(!IsPostBack)\
will not allow the page to post back again n again bcoz it reduces the performance.
