Print GridView Data In Asp.Net Using C# VB JavaScript

To Print GridView Data In Asp.Net Using C# And VB.NET, I have placed GridView inside a Div and this Div will be called for printing using javascript.

Print window will be opened in onclick event of Button. Javascript to print data is written in Page Load event of page and registered with RegisterStartupScript.
