Try using the MobileCapabilities class like so..
MobileCapabilities currentCapabilities = (MobileCapabilities)Request.Browser;
currentCapabilities.ScreenPixelsHeight or currentCapabilities.ScreenCharactersHeight should be what you're looking for.
You will be lucky to get accurate readings unless you have the correct attributes in your .browser files. See the sticky post on this forum for making such .browser files. I am currently looking for a site to share such files with other developers, but no
joy at this stage.
Cheers, good luck...
