I have a web app that I want to make the pages render correctly based on what
type of browser is connected. How can I determine if the browser is the
desktop IE version or a handheld device version?
 
that doesn't tell me if its a handheld device such as a blackberry browser
(IE version) or a desktop IE version. I ran the URL below in a test web form
and the params are the same except for the Minor version, the blackberry is
..8 and the desktop is 6. Thats the only difference. Is that what I need to
look for though to determine what page to direct them to or stylesheet to use
 
Hello igotyourdotnet,

As for client browser detection, generally server-side application(http
based web application) will use the http UserAgent header for reference.
For example, IE desktop browser will send the following http UserAgent
header

=========
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322;
..NET CLR 2.0.50727; .NET CLR 3.0.04506.30; InfoPath.2)
=========

And in ASP.NET, it use a browser setting to maintain an supported
browser/device list. This list originally configured in machine.config's
<browserCaps> element(in .net 2.0) or through the .browser files under
"browsers" folder under framework folder (for .net 2.0). At runtime,
ASP.NET will search for the certain browser type that matchs the useragent
http header and load the corresponding browser info into HttpRequest's
Browser property for later browser specific processing use. However, it is
still our duty to determine how we should deal with the control or page's
output according to the browser type. In ASP.NET 2.0, it provide a adapter
based archietcture for dealing with page/control rendering for different
browser.

For your scenario, if you just want to provide different html output for
different browser/device(mobile or not) and do not want to use the
ASP.NET's multi-browser support, I think you need to maintain a own browser
list and detect browser type through the http useragent header or the
Browser property as Gregory has mentioned:
