WP7Devwith HTML & JS

Silverlight and the web have a history

but Silverlight doesn't work in the browser (IE Mobile)

on WP7

You can put the browser inside a Silverlight app

though

Microsoft.Phone.Controls.WebBrows

er

Simplest use:.NavigateToString(

)

Demo

A common request:

HTML Help

Loading files from IsolatedStorage

.Navigate()

Demo

WebBrowser doesn't include a back stackbut it's easy to create your

own

Demo

private readonly Stack<Uri> historyList = new Stack<Uri>();

protected override void OnBackKeyPress(CancelEventArgs e){ if (this.historyList.Count > 1) { this.historyList.Pop(); this.webBrowser1.Navigate(this.historyList.Peek()); e.Cancel = true; }

base.OnBackKeyPress(e);}

private void webBrowser1_Navigated(object sender, NavigationEventArgs e)

{ if ((this.historyList.Count == 0) || (e.Uri != this.historyList.Peek())) { this.historyList.Push(e.Uri); }}

Seriously consider

alternatives though

hint: Don't do it!

Where WebBrowser can be useful:

interacting with external websites

IsScriptEnabled

allows JS on page to call .net code

and .net code to call JS functions

Authorising with OAuthOr

taking in-app payments

Can we do more?

Why might we want to?

There are more mobile platforms than just Windows Phone 7

(Shhh!)

All the different platforms use different

programming languages

But everyone understands

HTML, JS & CSS

Introducing

build cross-platform mobile apps in HTML and JavaScript and still take advantage

of core, native, features

iPhoneAndroid

BlackberrySymbian

PalmWindows Phone

7!

Write the HTML, JS & CSS once*

and then recompile for each platform

*but you may want/need some variation

navigator.notification.vibrate()

navigator.geolocation.getCurrentPosition(

)

navigator.orientation.getCurrentOrientati

on()

navigator.network.isReachable()

navigator.sms.send()

navigator.telephony.call()

navigator.camera.getPicture()

Demo

That sounds amazing!

What are the cons?

- Not all platforms support/expose the same

functionality- Metro harder to mimic

- Debugging harder- WP7 support not finished, yet!

Consider it if you want to go cross-platform

It's OSS & contributions welcome
