Has anyone had any luck w/ using Request.Browser in ASP.NET 2.0? Specifically the Request.Browser.ScreenPixelsHeight, Request.Browser.ScreenPixelsWidth don't seem to return correct results. When I check these values they just report 640x480 which is not my current resolution (1600x1200). I tried it in FireFox and IE so it doesn't appear to be a browser issue. Is there anything I can do to make these properties return correct values? I tried to google for this info, but surprisingly there isn't much out there...
Thanks for any insight you can provide. MK

The property you are requesting is actually a member of HttpCapabilitiesBase It's values are provided from the servers config files, NOT from the client itself - you would have to use javascript to retrieve client side values.

Afaik all of the browser capabilities are extracted from the http headers sent by the client to the server. Asp.net 2.0 contains a very powerful technology to accomplish this using a set of regular expressions, applied to the aforementioned headers: you could access the code for each one of them (and add you own, if needed) in the \v2.0.50727\CONFIG\Browsers folder, checking out every .browser file. You should see that ScreenPixelsWidth/Height is available only for a small set of known user agent, namely Treo600 and other mobile devices which, in fact, send these informations embedded in one of the http headers they use. To extract those values from the browsers not supported by this mechanism you should use javascript, if available.

Thanks Efran, this does help. I am familiar w/ the http headers and was figuring this info must be coming from there, but as to how I wasn't sure. It makes sense that these properties would be more applicable to hand-held devices and such, however it would be nice to see a little bit more detailed msdn documentation on this class and these methods like you've provided below.
Thanks for your input MK

Yes i can use a javascript to get the screen resolution but if i want to set the height and width of any of my page's control based on the client resolution then what should i do. If any body has an idea then let me know
S11223J2 Currently, Timberland is one of the most famous Timberland Classic brands. Throughout the 1990s, the popularity of the Timberland Kids Boot reached an important point. Also, in that time, the company added more mens Timberland 6 Inch products and lines to its catalog. Now, the prestige as a Timberland custom boots brand with excellent products is unquestionable. In preparation for the upcoming cold seasons, the company has launched its collection called Timberland Women's Boots, which is already available at the Timberland stores. http://www.timberlander.com/products_all.html
