Recently when I was testing my ASP.Net application on different browsers, I found that in some of the browsers the controls did not work as expected.   These browsers were not in the list of compatible browsers mentioned at following URL:  http://www.telerik.com/aspnet-ajax/tech-sheets/browser-support

I then tried to come up with a method in JavaScript that would check if the current browser matched any one of the compatible browser name and browser version mentioned in above URL.  Then I could simply call this JavaScript method in the  page load event of master page and alert the user that the browser he or she is using is not compatible with the website.

It would be nice if such a method was there as part of RadControls library for ASP.Net AJAX. Such a method could be defined on client-side as well on the server-side.  It would  make life easier for a developer using RadControls, since users of the web site could be easily warned if they were using a browser that RadControls did not support.  Right now end users would just see the application behaving strangely when RadControls are rendered on an unsupported browser.
