Ok, I can detect all the browser details with Request.Browser.<whatever>.

One thing I think I may find use for this is for switching style sheets. Say, I have 2 stylesheets, StyleIE7.css and StyleFirefox.css.

If(Request.Browser.Browser.ToString() == "Firefox")

{

    <put code here for the master page to use StyleFirefox.css>;

}

Is this possible? How about using StringBuilder from System.Text class? Thanks

Hi,

You can change by changing the theme of the page. create two theme in you website and each contains a css file, one is StyleIE7.css and another is StyleFirefox.css. In the Page_PreInit event check the browser type and change the theme of the page. Then the website will apply the css file under the associate theme folder.

The following is a sample code.
    protected void Page_PreInit(object sender, EventArgs e)
    {
        if (Request.Browser.Browser == "Firefox")
            Page.Theme = "SkinFile";
        else
            Page.Theme = "Basic";
    }

Please let me know if it works.

aha it works :)

but how about my masterpage? will the theme's body{} element override the masterpage's css' body{} element?
