SharePoint 2010 Wizardry with Silverlight Widget and Web Part Communication
Innovation is Key to Success • Consumer Focus • “What incredible benefits can we give to the customer? Where can we take the customer? Not starting by sitting down with the engineers and figure out what awesome technology we have and how are we going to market that…” • – Steve Jobs • “The way to achieve the best long term value is to build real value in the world” • – Mark Zuckerberg
Understand This Principle • Awesome technology is adopted if it provides a benefit.
Some Great Technology • SharePoint - the last slide should tell you just how flexible SharePoint as a platform actually is. Flexibility is key here • Smart Phones – Windows Phone 7, Android, and iPhones place dotted lines around the form applications can take but allows for highly consistent experiences on the platform. Consistency is key here • Windows 8 and iOS– Attempt to provide flexibility and consistency over multiple form factors. • Social Platforms – Facebook, Twitter, WordPress
SharePoint as a Development Platform • Exemplifies the 80/20 Rule • SharePoint can be low cost using all out of the box features and branding • The last 20% represent specialized purposes usually at a higher cost • Benefits of that last 20% may not exceed the cost of development if poor choices are made
SharePoint Development Approaches • A major decision point in this last 20% is on approach The choices include: • Creating applications from multiple third party web parts (and features) • Super user development using native capabilities • Rolling your own widgets with compiled and middle tier code • Purchasing complete sub systems such as pmPoint and Project Server • Some combination of everything
Good Technology + Vision = Excellent Applications • Think in terms of an application domain not just a collection of widgets that meet line item requirements • Stay away from monolithic thinking • Keep the idea of atomic development a first class principle. • Leverage as much of the platform as practical • How should platform components communicate with each other to enhance the value and consistency
Linking Applications and Widgets • Huge trend enabling dynamic linking between applications and components as well as more robust communication between components • Video
Building a Basic Silverlight Web Part • Demo • … and web part islands
Some Observations • Web parts tend to live in self contained islands • Connecting to other web parts OTB is simple but has limited functionality • It takes work to connect in ways that reach the vision presented in the video
HTML5 Affiliated Communication APIs Web Messaging Web Sockets Server Sent Events Web Workers Node.js
Cross Component Communication in SharePoint • New HTML5 standards when integrated with SharePoint open up the platform for some really unique possibilities • Middle Tier Development with JQuery • Silverlight has rich connectivity into SharePoint
Silverlight/XAML Web Client Duplex Services ScriptObject HTMLPage SOAP/WCF/RIA LocalMessageReceiver LocalMessageSender
Communicating to the Host Page • public void HideHTML(string name) • { • ScriptObjectobj = (ScriptObject)HtmlPage.Window.GetProperty("HideHTML"); • obj.InvokeSelf(name); • } • public void ShowHTML(string name) • { • ScriptObjectobj = (ScriptObject)HtmlPage.Window.GetProperty("ShowHTML"); • obj.InvokeSelf(name); • }
Communicating to the Host Page • <asp:ContentContentPlaceHolderId="PlaceHolderAdditionalPageHead" runat="server"> • <script type="text/javascript" src="/_layouts/Xaptic/js/jquery-1.4.4.min.js"></script>
Communicating to the Host Page • <script type="text/javascript"> • function AddToHeader(css) { • $('head').append(css); • } • function MoveHTMLTo(name, top, left) { • $('#' + name).css('top', top); • $('#' + name).css('left', left); • } • </script>
Communication Between Local Silverlight-Based Applications • http://msdn.microsoft.com/en-us/library/dd833063(v=vs.95).aspx • // In the receiving application: • LocalMessageReceivermessageReceiver = new LocalMessageReceiver("receiver", ReceiverNameScope.Global, LocalMessageReceiver.AnyDomain); • // In the sending application: • LocalMessageSendermessageSender = new LocalMessageSender( "receiver", LocalMessageSender.Global);
Making Things a bit Easier • Upload and Drag / Drop • Easier to add properties • Leverage the web part concept as atomic level widgets • Build in communication mechanisms beyond connected web parts
Communication Between Local Silverlight-Based Applications • send = new LocalMessageSender(xaptic.GetProperty("SendTo"), System.Windows.Messaging.LocalMessageSender.Global); • send.SendCompleted += (object sender, SendCompletedEventArgs e) => • {}; • allowedSenderDomains.Add("localhost"); • allowedSenderDomains.Add("dev"); • allowedSenderDomains.Add("dev01.com"); • receiver = new LocalMessageReceiver(xaptic.GetProperty("ReceiveFrom"), ReceiverNameScope.Global, allowedSenderDomains); • receiver.MessageReceived += (object sender, MessageReceivedEventArgs e) => { L3.Content = e.Message; }; • receiver.Listen();
Putting it all Together • XAPTIC • A Silverlight Widget Platform for Prototyping Rich UI’s in SharePoint 2010
