IsPostBack property indicates that whether this is the first time user has requested fort the page or it is reloaded based on any response on postback. This property checks for __VIEWSTATE or __EVENTTARGET parameter in Request object. if these parameters are absent that means it is requested for the first time and if these parameters are present then this request is not first request. refer this link and go thru each post http://www.c-sharpcorner.com/Forums/Thread/195826/what-is-use-of-ispostback-in-Asp-Net.aspx Regards Iftikar

Hi It is the property in the System.Web.UI namespace. . IsPostback property is used to Gets a value that indicates whether the page is being rendered for the first time or is being loaded in response to a postback. This IsPostBack property returns the boolean value either True or False. In ASP.Net the Page Load is event is fired every time a page is loaded. This is true even if the page is loaded as part of a submit button click. You may need to identify if the page load event is called as part of a page submit or if it is a fresh page rendering. Because in case of page submit you may want to skip several task like populating the data again etc. The IsPostBack property can be used to determine if the page is submitted to itself. When a form is posted (submitted) back to the same page that contains it it's called a post back. ASP.NET provides a property called IsPostBack that is TRUE when the page is being loaded as a result of a post back and is FALSE otherwise. We can check the value of this property and based on the value we can populate the controls in the page. If the property is TRUE that means it is a postback (submit) and no need to populate all the values again.
