Are there any asp.net server controls that only work with Internet Explorer. I am looking for a list so that I can know what to avoid putting into my webforms application.
I am looking for something like a list of controls and those that downlevel firefox and safari for example. I understand that the client side validation javascript is IE only. Is this still true ?
I don’t believe there are any controls that just don’t work in non-IE browsers. ASP.NET will render some webform tags different based on the requesting browser. 4GuysFromRolla has a pretty good write-up on this: A Look at ASP.NET’s Adaptive Rendering.
I had some issues on a recent web application I built where the HTML being output for FireFox was noticeably different than the HTML being output for IE on certain controls. I used the 4Guys resource and it helped but I eventually just dropped the offending web form control and went a different route.
As always, make sure to test your website on all browser platforms during development.
