Detect Mobile and Tablet devices

Feb 09, 2012 10:09 PM|LINK

Hi Friends...Can anyone of you help me in my below query....

In my web application I use the following code to detect any mobile devices and redirect to the mobile version of site.

            string strUserAgent = Request.UserAgent.ToString().ToLower();
            if (strUserAgent != null)
            {
                if ((Request.Browser.IsMobileDevice == true ||
                    strUserAgent.Contains("iphone") || strUserAgent.Contains("ipod") ||
                    strUserAgent.Contains("symbian") || strUserAgent.Contains("android") ||
                    strUserAgent.Contains("windows ce") || strUserAgent.Contains("blackberry") ||
                    strUserAgent.Contains("palm") || (strUserAgent.Contains("mobile") && !strUserAgent.Contains("ipad")) ||
                    strUserAgent.Contains("opera mini")) && (Session["VFS"] == null))
                {
                    string fullsiteurl = Request.RawUrl.ToString();
                    Response.Redirect("http://m.huggies.com");
                }
            }

Now, I wanted to do a check for tablet devices and redirect to desktop version of site if it is a tablet device. As of now it is done in the above code but only for iPad.

I need to add conditions for the following tablet devices and all others too that are not listed. Can anyone help me?

You could use the Request.Browser.ScreenPixelsWidth to determine if it meets a certain size applicable to view the desktop version. Recommend you check what sort of sizes they use.
