Silverlight is designed for UI flexibility

Customize the look of an application without changing it’s behavior

2 levels of customization:

• Styling: Small visual changes on an element (Font, background color, etc)

• Skinning: Replacing an element’s entire visual tree

UI Customization

Theming: Silverlight Toolkit

http://www.codeplex.com/Silverlight/

Layout containers• Canvas, Grid, StackPanel, Border

Layout properties• Width, MinWidth, MaxWidth, ActualWidth

• Height, MinHeight, MaxHeight, ActualHeight

• Margin and Padding

Layout Controls

Cross Domain Policy Support (Silverlight and Flash policy files)

Socket Support

Background network treading (asynchronous data)

• Socket and HTTP

Duplex Communication (ServerPush)

• Using WCF

• Instant Apps, Monitoring, Chat etc

ADO.NET Data Services

• ADO.NET Data Services ships in .NET 3.5 SP1

• Silverlight has client access bits (REST)

Network

Asynchronous web services supported

proxy.BeginGetTransactionList( new AsyncCallback(OnTransactionDataLoaded),

null);

private void OnTransactionDataLoaded(IAsyncResult iar){ transactionList = proxy.EndGetTransactionList(iar).ToList();}

Start the async web service call

Handle the web service completion event

Asynchronous Support

Core XML reading & writing capabilities

LINQ to XML

XmlReader xr = XmlReader.Create(new StringReader(RawResponse));

xr.ReadToFollowing("Item");string playerNodeText = xr.Value;string playerNameAttribute = xr.GetAttribute("Name");

Initialise the reader

Find a node and read its value

XmlReader & XmlWriter

LINQ = Language INtegrated Query • Allows query expressions to benefit from compile-time

syntax checking, static typing & Intellisense

• Works on any IEnumerable<T>-based source

Supports querying of in-memory data sources

var filteredPlayers = from p in players where p.HomeRuns > 20 orderby p.HomeRuns descending select p;

Return all players with more than twenty home runs, sorted

LINQ

{{FileName=“Html.html”, FileImageUrl=“html.jpg”},{FileName=“Image.jpg”, FileImageUrl=“jpg.jpg”}}

Data Template:

Data (.NET Object):

Bind using ItemsControl (List Control):

Data Binding

Silverlight lives in the browser Sandbox

Developers cannot extend the sandbox

Silverlight extends in a secure way• Local storage (isolated storage)

• Cookies on roids

• 1 MB

• Extendable by user initiation

• FileOpen dialog …

Silverlight Sandbox

HTML access available in new namespace

HtmlPage.Navigate("http://www.microsoft.com");String server = HtmlPage.DocumentUri.Host;

using System.Windows.Browser;

HtmlElement myButton = HtmlPage.Document.GetElementByID("myButtonID");myButton.AttachEvent("onclick", new EventHandler(this.myButtonClicked));

private void myButtonClicked(object sender, EventArgs e) { ... }

Static HtmlPage class provides entry point

Hookup events, call methods, or access properties

Access the HTML DOM from Managed Code

Mark a property, method or event as [Scriptable]

WebApplication.Current.RegisterScriptableObject ("EntryPoint", this);

[Scriptable]public void Search(string Name) { ... }

var control = document.getElementById("SilverlightControl");control.Content.EntryPoint.Search(input.value);

Register a scriptable object

Access the managed object from script

Access Managed Code from JavaScript

• Provides seamless viewing & zooming of huge images

• Loads only the data necessary to show the part of an image the user is viewing

• Effectively turns a large image into an efficiently scaling vector

Deep Zoom

Versioning and IE Modes

Compatibility Modes IE8 Standard (default) – CSS 2.1-compliant IE7 Emulation – backward compatibility with IE7 IE5 Compatible – IE5 rendering behavior

Mode Switches (Opt-in) HTTP header: X-UA-Compatible: IE=7

– For example, Web.Config in IIS7:<httpProtocol> <customHeaders> <clear /> <add name="X-UA-Compatible" value="IE=7" /> </customHeaders> </httpProtocol>

JavaScript: document.documentMode Meta tag: <meta http-equiv="X-UA-Compatible" content="IE=7">

Web Slices

Page Content Subscription• RSS-based subscriptions to portions of a Web page• Favorites Bar with update notification• Content-hover discovery• In-place content preview

Implementation• Enabled by adding HTML annotations• hAtom Microformat and Web Slice format• Refresh interval configurable

Sample HTML Annotations …

Add Web Slice delicategeniusblog.com

<div id="dg_recent_comments"><abbr></abbr><?php if (function_exists('get_recent_comments')) { ?> <li><h2 class="entry-title"><?php _e('Recent Comments:'); ?></h2> <ul><?php get_recent_comments(); ?></ul> </li><?php } ?> </div>

<div class="hslice" id="dg_recent_comments"><abbr class="ttl" title="60"></abbr><?php if (function_exists('get_recent_comments')) { ?> <li class="entry-content"><h2 class="entry-title"><?php _e('Recent

Comments:'); ?></h2> <ul><?php get_recent_comments(); ?></ul> </li><?php } ?> </div>

Web Slice Format

• hAtom Microformat describes a feed & items

• Web Slice builds on hAtom

– hAtom can represent static content

– Web Slice is dynamic content

• Web Slice reuses properties on hAtom

– Adds optional properties for subscribing

• ttl – time-to-live value

• feedurl – alternative path to get updates

• endtime – When the feed item is no longer relevant

– Can be applied to an hAtom

Developer Tools

Built-In Developer Tools• Dynamic toggling of rendering modes• 3 modes – HTML, CSS, JavaScript

HTML & CSS Explorer• Exposes internal representation of DOM tree

and CSS styles• Real-time editing and rendering• Element-based style explorer• CSS file-based view in CSS mode

Developer Tools

JavaScript DebuggerExecution control• line and context-based breakpoints• Step into, over, out, continue; break all (pause)

Variable Inspection• Scope sensitive (local, global, etc.)• Set watch variables

Call Stack Manipulation• Dynamic call stack traversal

Custom Script Execution• Immediate tab
