Hi Murari, PostBack is the name given to the process of submitting an ASP . NET page to the server for processing for More information : http://www.c-sharpcorner.com/uploadfile/2f73dd/what-is-postback-in-Asp-Net/ Example : If you have an example, %@ Page Language = "C#" AutoEventWireup = "true" CodeBehind = "WebForm1.aspx.cs" Inherits = "WebApplication1.WebForm1" % > > html xmlns = "http://www.w3.org/1999/xhtml" > head runat = "server" > head > body > form id = "form1" runat = "server" > div > asp:TextBox ID = "TextBox1" runat = "server" > asp:TextBox > asp:Button ID = "Button1" runat = "server" Text = "Button" /> div > form > body > html > And our code is , using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace WebApplication1 { public partial class WebForm1 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { TextBox1.Text = "On Load"; } } } enter some text in text box , IN default the text box will have "on Load" text. change the text and click ok. Whenever you click the submit the button , the request will send to the server and the page load event will trigger and again the text box value will be "On Load". Test it!.. you can understand easily!...
