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 });             }            

ToolTip on specific DropdownList item in asp.net c#

Today i am talking about tooltip, First of all i introduce you , what is tooltip? When our mouse cursor move over the object then appear a rectangle shape with text this things known as tooltip. When we work with particular item then easy set the tooltip on it. But when we work on collection then we put some ideas on it. Like first to access each item from the collection then apply tooltip on each accessed item. Today, i want to give a simple example on it. I have a database table with three columns, see below:


Database table(country table)

CREATE TABLE [dbo].[country] (
    [CountryId]    INT            IDENTITY (1, 1) NOT NULL,
    [CountryName]  NVARCHAR (MAX) NULL,
    [Countryimage] NVARCHAR (MAX) NULL,
    PRIMARY KEY CLUSTERED ([CountryId] ASC)
);

First to add some item in the table after then you have to access items. If you want to add items in the table by the help visual studio server explorer then do the following.

Right click on your table name --> Select show table data

Source Code
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default9.aspx.cs" Inherits="Default9" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>


</head>
<body>
    <form id="form1" runat="server">
    <div>
<asp:DropDownList ID="DropDownList1" runat="server"  Height="26px" OnDataBound="DropDownList1_DataBound" Width="142px" DataSourceID="SqlDataSource1" DataTextField="CountryName" DataValueField="CountryId"></asp:DropDownList>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT * FROM [country]"></asp:SqlDataSource>
    </div>
    </form>
</body>
</html>

How to design above mentioned code. The answer is :Bind the DropdownList with the SqlDataSource also SqlDataSource Control connect with database table. The above mentioned code automatically generated by the visual studio.

Code Behind Code

protected void DropDownList1_DataBound(object sender, EventArgs e)
    {
        DropDownList ddl = sender as DropDownList;
        if (ddl != null)
        {
            foreach (ListItem li in ddl.Items)
            {
                li.Attributes["title"] = li.Text;

            }
        }
    }

After bind the Dropdownlist you have to access each item from the list by using DataBound event. Use foreach loop to access all item one by one from the list also apply tooltip on each item by the help of Attribute property.

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

Print the asp.net webpage using button

Introduction Today i am talking about printing, and how to print the content or you can say selected content in asp.net. If you have a webpage and you want to print this then you have to choose command key (ctrl+p) for that.
