How to use Tabs in ASP.NET CORE

I want to show Components in a tabs , so first of all create few components. In this project we have three components, First View Component  public class AllViewComponent : ViewComponent     {         private readonly UserManager<ApplicationUser> _userManager;         public AllViewComponent(UserManager<ApplicationUser> userManager)         {             _userManager = userManager;         }         public async Task<IViewComponentResult> InvokeAsync()         {             List<StudentViewModel> allUsers = new List<StudentViewModel>();             var items = await _userManager.Users.ToListAsync();             foreach (var item in items)             {                 allUsers.Add(new StudentViewModel {Id=item.Id, EnrollmentNo = item.EnrollmentNo, FatherName = item.FatherName, Name = item.Name, Age = item.Age, Birthdate = item.Birthdate, Address = item.Address, Gender = item.Gender, Email = item.Email });             }            

How to bind label control in asp.net

Step-1: Open Visual Studio IDE
Step-2 : Create New Web Project

ASP.NET empty website


Step-3: In Solution Explorer Add new item 
Solution Explorer Add new item


Step-4: Select web form in middle pane also select c# in left pane

Step-5: Change name of the webform as "labelbind.aspx" also select place code in separate file check box
Step-6:   Right click on  Project name and add new item  again.
Step-7: Open a new dialog window Select SQL SERVER database  name as a "database.mdf"
Step-8: After click ok Button . a new dialog appear on the screen 
Do you want to place the file in App_data folder
Step-9: Click Ok Button in dialog window
Step-10: Open Server Explorer
Step-11 Make a new table inside Database

Step-12:
make a new table


Step-13: fill This Table with Some value
Step-14: Open  " labelbind.aspx " page
Step-15: Drag and Drop label control onto the labelbind.aspx page from toolbox

Step-16: Add this code in Design page



<%@ Page Language="C#" AutoEventWireup="true" CodeFile="labelbind.aspx.cs" Inherits="labelbind" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:Label ID="Label1" runat="server" Text="">
            UserId:<%# myname %>


        </asp:Label>
    </div>
    </form>
</body>
</html>

Step-17 Add this code in .cs file


using System;
using System.Data.SqlClient;

public partial class labelbind : System.Web.UI.Page
{
    public string myname;
    SqlConnection con = new SqlConnection();
    SqlCommand cmd = new SqlCommand();


    protected void Page_Load(object sender, EventArgs e)
    {
        con.ConnectionString = @"Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\Database.mdf;Integrated Security=True";
        con.Open();
        cmd.CommandText = "select * from [Employee]";
        cmd.Connection = con;
        SqlDataReader rd = cmd.ExecuteReader();
        while (rd.Read())
        {
            myname = rd["Emp_Name"].ToString ();

        }
        this.DataBind();

     

    }
}


OutPut 


bind label output

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

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

Memory representation of Linked List Data Structures in C Language

                                 Memory representation of Linked List              In memory the linked list is stored in scattered cells (locations).The memory for each node is allocated dynamically means as and when required. So the Linked List can increase as per the user wish and the size is not fixed, it can vary.                Suppose first node of linked list is allocated with an address 1008. Its graphical representation looks like the figure shown below:       Suppose next node is allocated at an address 506, so the list becomes,   Suppose next node is allocated with an address with an address 10,s the list become, The other way to represent the linked list is as shown below:  In the above representation the data stored in the linked list is “INDIA”, the information part of each node contains one character. The external pointer root points to first node’s address 1005. The link part of the node containing information I contains 1007, the address of
