I'm goingto create an asp.n开发者_运维问答et control which should be cross browser. and support some skin - multilanguage and rtl & ltr support. I want to know what should I consider and also looking for a good article

Write valid xhtml.

Read this article on How to make Cross Browser Websites. It doesn't really have to do with if you use asp.net or php to create re-usable web-controls / sites. You just need to follow the standards and maybe apply some hacks if you want to support older versions of web-browsers.

Have a look at this series: Building ASP.NET User and Server Controls

Cross browser designs generally depends on what kinda design features you want to support, best thing to get started with is learning asp.net control adapters, It's basically bunch of ready made samples that shows how to detect browser early in the execution of the request and reflect to the design using in-built actions provided by asp.net technology, or write your own!

Hope this helps
