How to use TextChanged event of TextBox with AutoPostBack in ASP.NET

By Jacob

ASP.NET application works on AutoPostBack model, i mean, if we want to run code behind event like TextChanged event then we must set AutoPostBack property is true.
  <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %>

 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

 <html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        Search Item<asp:TextBox ID="TextBox1" runat="server" 
            AutoPostBack="True" Width="174px" ontextchanged="TextBox1_TextChanged"></asp:TextBox>
        <br />
        <br />
    </div>
    <asp:Label ID="Label1" runat="server"></asp:Label>
    </form>
</body>
</html>
Code Behind Code

 using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

 public partial class Default3 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

     }
    protected void TextBox1_TextChanged(object sender, EventArgs e)
    {
        string[] arr = { "jacob", "lefore", "martin" };

         foreach (string item in arr)
{
if (item==TextBox1 .Text)
        {
            Label1.Text = item;

        } 
}
        
    }
}

Output

This example shows that TextChanged event occurs when user focus out from the TextBox. You can search item on TextChanged event.

Polynomial representation using Linked List for Data Structure in 'C'

By
Polynomial representation using Linked List The linked list can be used to represent a polynomial of any degree. Simply the information field is changed according to the number of variables used in the polynomial. If a single variable is used in the polynomial the information field of the node contains two parts: one for coefficient of variable and the other for degree of variable. Let us consider an example to represent a polynomial using linked list as follows: Polynomial:      3x 3 -4x 2 +2x-9 Linked List: In the above linked list, the external pointer ‘ROOT’ point to the first node of the linked list. The first node of the linked list contains the information about the variable with the highest degree. The first node points to the next node with next lowest degree of the variable. Representation of a polynomial using the linked list is beneficial when the operations on the polynomial like addition and subtractions are performed. The resulting polynomial can also
