title: How to open pop-up window in ASP.NET web application?
body: <p>I'm using a GridView in ASP.NET web application and want to open something like a "new form" (like in Windows Forms application) which will contain the selected GridView row data. I don't have issues selecting the row and the data, I just want to know how to open a new pop-up window, or secondary page or something like that, and how to pass the information to newly opened pop-up.</p>
