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 use caching in ASP.NET

Introduction
Caching as the name suggest, is used to store data temporarily either on a Web server or on the client-side. Caching is useful in situation where several programs continually access the same set of data. This data can be easily stored in a cache and used in future. Accessing a database in an ASP.NET page is generally a slow and time-consuming process that involves connecting to the database and retrieving data from it. Caching is the best way to improve the performance of your Web application since it allows you to access data from the cache itself, which is quicker than if you were to retrieve the data from the database on each request. Therefore, caching not only reduces the processing time of a Web application, but also reduces network traffic; thereby improving the performance of your Web application and enhancing user experience.

Example of caching using output caching 


<%@ Page Language="C#" %>
<%@ OutputCache Duration ="10" VaryByParam ="none" %>
<!DOCTYPE html>
<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        Label2.Text = DateTime.Now.ToString();
    }
</script>

<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="The below displayed time was cached for 10 seconds keep refreshing the page to see the changes"></asp:Label>
        </div>
        <asp:Label ID="Label2" runat="server" Text=""></asp:Label>
    </form>
</body>
</html>
Output
How to use caching in ASP.NET

Here in this example time label will changed after 10 second.

VaryByParam Attribute 
The VaryByParam attribute is used to cache different copies of a Web page when it is generated dynamically, based on the parameters received in the form of HTTP POST or HTTP GET.

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
