I am developing a web application and that will be mainly used in Windows CE hand sets which has Windows CE 4.2 with IE 6 and I just wanted to know whether AJAX and JQuery can be used in my web app or not.
I tried using UpdatePanel in my project, but, it seems to be not working. Any advice will greatly appreciated.
To have support for AJAX you need support for Javascript and for XMLHttpRequest object. A WinCE image can include support for both:
If you have IE6 mobile installed on your wince image I can imagine that both componente are included in the wince image itself.
As a consequence also JQuery is supported but if you use IE6 you have to use at max the 1.9 version: see here
