ASP.NET MVC Action Filter to Detect Mobile Devices Update

Steve asked me in a previous post for a sample application for detecting a mobile device and rendering a mobile view in ASP.NET MVC.

You can download a sample MVC app here.

The app is the same as the ASP.NET MVC template that the "GU" put together, with the added mobile action filter and views.

I've also updated my mobile browser detection. Turns out not to be so straight forward as new phones are coming out all the time with different User Agents etc. This is the best "generic" way I could find:

if (filterContext.HttpContext.Request.Browser.IsMobileDevice || 
	filterContext.HttpContext.Request.ServerVariables["HTTP_ACCEPT"].Contains("text/vnd.wap.wml") ||
	filterContext.HttpContext.Request.ServerVariables["HTTP_ACCEPT"].Contains("application/vnd.wap.xhtml+xml")
)

Hope this help Steve, let me know how you get on.

# re: ASP.NET MVC Action Filter to Detect Mobile Devices Update

Back in May, Scott Guthrie wrote about a routing feature in Preview 3. It allows the app to detect requests for XML:

routes.MapRoute("Products-Browser",
"products/browse/{category}.{format}",
new {controller = "Products", action = "Browse"});

It looks like it could perform the same function. The full blog posting is here: weblogs.asp.net/.../...-mvc-preview-3-release.aspx 10/7/2008 2:14 PM | Cody Skidmore

I was just playing around with the MobileUserFilterAttribute the your created in this app. You may want to verify the type of the filterContext.Result because it could be a RedirectToAction result, in which case you probably won't want to change the ViewName yet.

Otherwise, great work!

if you cant be bothered maintaining your own database of devices, you can also use an "on demand" service such as handsetdetection.com 11/19/2008 12:13 AM | qwerty design
