Making a Simple ASP.NET website

This is a continuation of my post on making a simple asp.net website.

Make a new folder named css in your project folder and add bootstrap.css file in this folder. You can download bootstrap from here . It will help in designing the website. Next we will be adding Update and delete button. And an Image to view the Profile pic of student. Also a gridview with pagination to view the data present in the database and a button in gridview itself to be used. The page will be styled using bootstrap as mentioned before and it will be a responsive page meaning you can  view the page on any screen you want.

So let’s get started. Open the Default.aspx and change it as following :

Default.aspx :

 


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