ASP.net Redirect to Mobile(Blackberry) version page

[berkshirea]

Hi guys, I am experimenting with a mobile version (for blackberry) of a site and would like the users to be redirected to this mobile site version. I used the simulator and a real blackberry but it's not redirecting.

I tested it for browser capabilities using the simulator and the real blackberry and gives the same info:

Browser type: Unknown
Browser version: 0.0
Major version: 0
Platform: Unknown
.
.
.



Below is the code for redirect:

Public Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)

If Request.Browser("IsMobileDevice") = "true" Or Request.Browser("Blackberry") = "true" Then

Response.Redirect("blackberry.aspx")
Else
Response.Redirect("desktop.aspx")
End If
End Sub


Thanks for any help.

try

If Request.Browser("IsMobileDevice") = True.ToString() Or Request.Browser("Blackberry") = True.ToString() Then
   Response.Redirect("blackberry.aspx")
Else
   Response.Redirect("desktop.aspx")
End If

that might be one reason.

However this logic is very intrusive. you would need to place it on every single page. I recommend using Master pages and Themes to style the webform. This way you keep 1 webform and simply alter the Theme/Master for display purposes.

either that or create your own HttpModule to redirect the user to the proper place (computer vs. mobile device)

try changing this:

Request.Browser("IsMobileDevice") = "true"

to this

Request.Browser("IsMobileDevice") = true 
OR
Request.Browser("IsMobileDevice")

Sorry, I made a mistake in my post. Here is the exact code we use on our site that works perfectly:

If Request.Browser.IsMobileDevice OrElse _
                Request.Browser("BlackBerry") = "true"
...
...
EndIf

Guys, thanks very much for your help.

I have found out that my server's browsercap in machine.config is out of date. I just updated it and now it seems to work.

Have a nice day.

Cheers!
