i used this code:
protected void Page_Load(object sender, EventArgs e)
{
    if (isMobileBrowser() == true)
    {
        Response.Redirect("~/Mobile/");
    }
 }


public static bool isMobileBrowser()
{

    HttpContext context = HttpContext.Current;


    if (context.Request.Browser.IsMobileDevice)
    {
        return true;
    }
    //THEN TRY CHECKING FOR THE HTTP_X_WAP_PROFILE HEADER
    if (context.Request.ServerVariables["HTTP_X_WAP_PROFILE"] != null)
    {
        return true;
    }
    //THEN TRY CHECKING THAT HTTP_ACCEPT EXISTS AND CONTAINS WAP
    if (context.Request.ServerVariables["HTTP_ACCEPT"] != null &&
        context.Request.ServerVariables["HTTP_ACCEPT"].ToLower().Contains("wap"))
    {
        return true;
    }
    //AND FINALLY CHECK THE HTTP_USER_AGENT
    //HEADER VARIABLE FOR ANY ONE OF THE FOLLOWING
    if (context.Request.ServerVariables["HTTP_USER_AGENT"] != null)
    {
        //Create a list of all mobile types
        string[] mobiles =
            new[]
            {
                "midp", "j2me", "avant", "docomo",
                "novarra", "palmos", "palmsource",
                "240x320", "opwv", "chtml",
                "pda", "windows ce", "mmp/",
                "blackberry", "mib/", "symbian",
                "wireless", "nokia", "hand", "mobi",
                "phone", "cdm", "up.b", "audio",
                "SIE-", "SEC-", "samsung", "HTC",
                "mot-", "mitsu", "sagem", "sony"
                , "alcatel", "lg", "eric", "vx",
                "NEC", "philips", "mmm", "xx",
                "panasonic", "sharp", "wap", "sch",
                "rover", "pocket", "benq", "java",
                "pt", "pg", "vox", "amoi",

            };

        //Loop through each item in the list created above
        //and check if the header contains that text
        foreach (string s in mobiles)
        {
            if (context.Request.ServerVariables["HTTP_USER_AGENT"].
                                                ToLower().Contains(s.ToLower()))
            {
                return true;
            }
        }
    }

    return false;

You will get better results if you use a 3rd party database like this one. You'll need to update it on some schedule.

I prefer using a URL rewrite. Something like

<rule name="Mobile Rewrite" patternSyntax="ECMAScript" stopProcessing="true">
    <match url=".*" ignoreCase="true" negate="false" />
    <conditions logicalGrouping="MatchAny" trackAllCaptures="false">
        <add input="{HTTP_USER_AGENT}" pattern="midp|mobile|phone" />
        <add input="{HTTP_X-Device-User-Agent}" pattern="midp|mobile|phone" />
        <add input="{HTTP_X-OperaMini-Phone-UA}" pattern="midp|mobile|phone" />
    </conditions>
    <action type="Redirect" url="http://mysite.mobi" appendQueryString="false" redirectType="Found" />
</rule>

Your problem is the line

Response.Redirect("~/Mobile/");

Open in new window


When you open the mobile path from the PC it is not redirecting you to the home page. But when you open from a mobile device you are redirected to

http://tendrustikurd.net/Mobile/SamePage.aspx

You should redirect the mobile users to the same page they browsed to

If I go to http://tendrustikurd.net/Login.aspx using a mobile I should be redirected to http://tendrustikurd.net/Mobile/Login.aspx and not http://tendrustikurd.net/Mobile/
