Hi,
On click of image button you can call a javascript function. And in that javascript function you just use "__doPostBack". Refer the links below:

http://wiki.asp.net/page.aspx/1082/dopostback-function/[^]

This will work in all the browsers. So no compatibility issue.

Try first to figure out, how fields are populated by different browsers. Use Fiddler for that.
What I see, that you have no exact action trigger. Chrome is for sure supporting ajax, that won't be the problem. But ASP.NET client support is not extensive enough. See this article: http://seejoelprogram.wordpress.com/2008/09/04/adding-google-chrome-to-aspnet-ajax/[^]
You can fine-tune the triggering mechanism, see this article: http://www.asp.net/web-forms/tutorials/aspnet-ajax/understanding-asp-net-ajax-updatepanel-triggers[^]
Of course, you can also not relay on built-in triggering and use Javascript as others suggested.
