Browser detection in ASP.NET
Here is a code snippet for detecting in which Internet browser a user is viewing your site.
Note that I usually use two stylesheets. The first, standard.css, contains the styles interpreted the same way by all browsers. I then use a second stylesheet to add or change any styles rendered differently in different browsers.
In the head tag of the relevant page (a .master page would be a good location) add the following lines (assuming that you use two stylesheets as described above):
<link href="/styles/standard.css" rel="stylesheet" type="text/css" />
<link runat="server" rel="stylesheet" type="text/css" id="stylesheet2" />
In the page_load sub of the same page, add the following code:
'Determine the correct css file depending on the browser
Dim httprequest1 As HttpBrowserCapabilities = Request.Browser
Select Case httprequest1.Browser
Case "IE"
If httprequest1.Version = "6.0" Then
stylesheet2.href = "ie6.css"
End If
Case "Firefox", "Mozilla"
stylesheet2.href = "firefox.css"
Case Else
stylesheet2.Href = ""
End Select
In this example, only two browsers are detected but you could of course add more. You can also add additional versions to each browser.
