1. Create a New ASP.NET Web Site. File>New Web Site>ASP.NET Web Site. I left my website with the defaults for my machine: Location = File System and Language Visual Basic.
2. Add a Button and a Textbox to the default.aspx
3. In the click event handler of the button (just double click on the button) add the code Button1.Text = TextBox1.Text.
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Button1.Text = TextBox1.Text
4. Run the Website to determine the URL for the page. For the mine it was: http://localhost:53814/WebSite2/Default.aspx
5. Create a web test and record clicking the button on the page. Test Menu>New Test>Web Test.
6. Looking at the Recorder - you can clearly see the HTML being recorded (See image below)
Converting this page to Ajax is as easy as easy as adding two controls - the ASP.NET Script Manager and the Update panel.
7. Open the page Default.aspx and from the toolbox and add a script manager above the button and an Update Panel
8. Move the Button and the Textbox into the UpdatePanel
9. Run a new Test Recording on the modified page. Menu>New Test>Web Test recording. Test Menu>New Test>Web Test.
10. You can see the exact same functionality is now being executed through Java Script -and being recorded whereas in 2005 the recorder would not have recorded those calls.
