Stuff I need to research & learn,

• Partial Rendering
• Update Panel control (AJAX Style)
• Script Manager
• Ajax Controls
• System.Web.UI.UserControl namespace
• XML Payload
• ViewState
• App_Data Folder
• Sharing Session Objects between Classic ASP and ASP.NET

Points to note ,

• Always notice the status bar in IE 7 when loading a web page.
• Cross browser Development > for example, Firefox, IE and other browsers. (I.E. Browser Agnostic)
