Answer / Nadine Pde

"IsPostBack"; is a property of the Page class in ASP.NET that indicates whether the page is being posted back (i.e., submitted through an HTTP POST request) or whether it's being requested for the first time (HTTP GET request). The purpose of IsPostBack is to differentiate between user interactions on the server-side and initial page loads, allowing developers to perform specific actions based on the state of the page.nFor example, when you want to reset form fields after a submission, you can check if the page is being posted back using IsPostBack: "if (!IsPostBack) {n // Code for setting default values or initializing form fieldsn}"
