I'll take from Google CDN. https://developers.google.com/speed/libraries/#jquery Create a JavaScript file under folder called Scripts and name that file as Script.js. Add the following script to that file. Using this script file we are going to call a server side method which is written in C#.

Hi all, in this series of blog posts I'll explain how to create ASP.Net web applications using a better structure. This is the part 1 of this blog series, so in this post I'll try to explain how to retrieve data from database. First go tot the Visual Studio and create a ASP.Net Empty Web Application project. Give a suitable name (I'll be using TestWeb). Create database and tables with some sample data. Now lets connect to that database using a connection string. Web.config <?xml version="1.0"?> <!--   For more information on how to configure your ASP.NET application, please visit   http://go.microsoft.com/fwlink/?LinkId=169433   --> <configuration>     <connectionStrings>         <add name="ProductDBConnectionString" connectionString="Data Source=LK-PRK\SQL2012DEV;Initial Catalog=ProductDB;Integrated Security=True"             providerName="System.Data.SqlClient" /...
