Kuldeep Chand I have tried my best to compile each and every aspect related to Advance ASP.NET WebForms with C# in this eBook with various kinds of Simple and Professional Level Web Applications Based Example Programs using Visual Studio’s Wizard and Manual Coding. It have written latest content on ASP.NET WebForms and I have tried my best to clear each and every Advance Concept like Master-Pages, Themes and Skins, ADO.NET for Database Driven Web Application, Rich Data Controls, Component Based Programming, ASP.NET AJAX, Caching, Custom User and Server Controls, Security Management, etc… in as easy language as possible. But since, the Whole ASP.NET is very big subject, so I have divided it in two parts to cover each and every aspect of it where this EBook covers only Advance Concepts while another eBook covers Core Concepts of ASP.NET WebForms. I believe that no other Advance ASP.NET WebForms with C# Book have as much good content as in this eBook is in Hindi Language because I have tried my best to include each and every advance concept related to ASP.NET and I wish, each and every buyer would be happy with the content of this eBook. If you read this EBook, you will sure get Good Understanding of Advance Concepts of ASP.NET WebForms to develop a Professional Level Web Application very easily plus this Advance Concept is also compulsory to learn if you want to become a Professional ASP.NET MVC Web Developer because Microsoft’s ASP.NET MVC and ASP.NET Webpages are based on these advance concepts too internally.
