Hi,

I am really new to ASP.net and have put together my first website.

Generally the website works fine in all browsers apart from the iPhone version of safari.

I have added to databound combo boxes to the page. The first one is a "master" category and the second is a "sub" category. Both combo boxes read their values from sproc's in SQL Sever 2005.

In addition I have set the "sub" category up so that it takes a parameter value from the "master" category i.e. on selection of a "master" category the relevant "sub" categories are populated automatically in the second combo.

As I said the above works fine with all browsers (inc mobile browsers for android etc) but for iphone safari the combo boxes just don't refresh to reflex the selections made by users.

Is there a common problems with this for the iphone? Is there anything I can do to diagnose the issue?

I have plans to do a mobile specific site. But I still need to get this working.

Any help would be great.

You're using postbacks to make all of this work ? ASP.NET changes how it renders according to the browser. What version of ASP.NET are you using ? A newer version may better know how to deal with an iPhone. Personally, I try to never use postbacks and handle everything with jQuery. In general I would recommend if you are new anyhow, using MVC instead of webforms and thus using jQuery and AJAX for things like this.
