5. Agenda Silverlight on SharePoint Benefits Challenges Getting started Architectural Pattern #1: Silverlight Proxy on SharePoint Web Services Architectural Pattern #2: Silverlight WebClient on Custom Runtime Services Architectural Pattern #3: Custom Client Adapter on SharePoint Web Services Architectural Pattern #4: Custom Client Adapter on Custom Runtime Services Setup and deployment

6. Silverlight on SharePoint Benefits Build compelling, rich internet applications (RIA) on the SharePoint platform Silverlight: provides rich user interfaces SharePoint: provides collaborative data Out-of-band communication between Silverlight and the SharePoint platform Example: rendering list items in Silverlight can be magnitudes faster than viewing the list in SharePoint pages Let the power of.NET run in the browser Silverlight: provides access to.NET libraries, such as: System, System.Net, System.Windows, System.Windows.Media, System.Xml, etc.

7. Silverlight on SharePoint Challenges Communication Issues Silverlight applications (.xap) run in the client browser SharePoint objects are accessed on the server Challenge: Provide a two-way mechanism for passing SharePoint data between the server and Silverlight Deployment Issues Web.config entries for Silverlight Web.config entries for other components (such as database connection strings) MIME-type settings for IIS Challenge: Include non-SharePoint configuration changes in a deployment package

8. Silverlight on SharePoint Getting Started Build a simple Silverlight application (.xap) as a proof-of-concept Plumb the Silverlight hosting control into your SharePoint Web Parts Example code on next slide Select a communication architecture for transferring data between the SharePoint platform and Silverlight Architectural patterns described in the remainder of this presentation Build out the entire solution

9. Silverlight Hosting Control in a Web Part //Class-level variable System.Web.UI.SilverlightControls.Silverlight silverlightControl; //Web Part's OnLoad event procedure: //Ensure there is a ScriptManager on the page protected override void OnLoad(EventArgs e) { base.OnLoad(e); ScriptManager scriptManager = ScriptManager.GetCurrent(this.Page); if (scriptManager == null) { scriptManager = new ScriptManager(); this.Controls.Add(scriptManager); } //continued on next slide

10. Silverlight Hosting Control in a Web Part protected override void CreateChildControls() { SPWeb = SPControl.GetContextWeb(Context); silverlightControl = new System.Web.UI.SilverlightControls.Silverlight(); silverlightControl.ID = "TechEdXaml"; silverlightControl.Source = thisWeb.Url + "/_layouts/TechEd/MyXap.xap"; silverlightControl.Width = new System.Web.UI.WebControls.Unit(700); silverlightControl.Height = new System.Web.UI.WebControls.Unit(500); silverlightControl.AutoUpgrade = true; silverlightControl.Enabled = true; silverlightControl.Visible = true; silverlightControl.HtmlAccess = HtmlAccess.Enabled; this.Controls.Add(silverlightControl); thisWeb.Dispose(); } protected override void Render(HtmlTextWriter writer) { silverlightControl.RenderControl(writer); }

13. Proxy on SharePoint Web Services Advantages/Disadvantages Advantages Least amount of 'plumbing' code Utilizes built-in objects and Web services Asynchronous Web service calls These calls do not block the Silverlight UI thread Disadvantages SharePoint functionality is limited to the operations supported by the built-in Web services Your Silverlight code must parse raw responses Possible cross-domain issues Asynchronous Web service calls

14. Proxy on SharePoint Web Services // Silverlight Client Code private void Pattern1_Click(object sender, RoutedEventArgs e) { // SPLists is the Service Reference to.../_vti_bin/lists.asmx SPLists.ListsSoapClient client = new SPLists.ListsSoapClient(); // Wire up the completed event handler client.GetListItemsCompleted += new EventHandler (client_GetListItemsCompleted); // Invoke the Web method client.GetListItemsAsync ("Customers", "", null, null, null, null, null); } void client_GetListItemsCompleted(object sender, Bonneville.SPLists.GetListItemsCompletedEventArgs e) { // ServiceResponse is a text block used to show the raw method response ServiceResponse.Text = e.Result.ToString(); }

Agenda Silverlight on SharePoint Architectural Pattern #1: Silverlight Proxy on SharePoint Web Services Architectural Pattern #2: Silverlight WebClient on Custom Runtime Services Architectural details Advantages/disadvantages Code samples and demo Architectural Pattern #3: Custom Client Adapter on SharePoint Web Services Architectural Pattern #4: Custom Client Adapter on Custom Runtime Services Setup and deployment

17. Non-SharePoint Platform WebClient on Custom Runtime Services Architectural Details Client Browser SharePoint Platform Fully-Rendered Web Part Silverlight Application Custom Web Services: MySPService1.asmxMySPService2.asmx WebClient Object User Interface Components Other 'Receivers': \_layouts\Receiver.aspx\_layouts\Receiver.ashx* * Requires Administrator Intervention Other Web Services: MyService1.asmxMyService2.asmx

18. WebClient on Custom Runtime Services Advantages/Disadvantages Advantages Provides full access to SharePoint and other line-of-business server applications Simple development in Silverlight Utilizes the built-in WebClient object No need to parse raw XML – the response is in your control Probably more efficient than pattern #1 Asynchronous Web service calls Disadvantages More server-side development effort required Possible cross-domain issues Asynchronous Web service calls

19. WebClient on Custom Runtime Services //Silverlight Client Code private void Pattern2_Click(object sender, RoutedEventArgs e) { // Build the Uri for the custom runtime service UriBuilder uriBldr = new UriBuilder("http://win2k3-base" +"/_layouts/techEd/techEdSharePointServerAdapter.aspx"); // Create a simple WebClient and wire up the Completed event handler WebClient wClient = new WebClient(); wClient.DownloadStringCompleted += new DownloadStringCompletedEventHandler(wClient_DownloadStringCompleted); //Call the runtime service wClient.DownloadStringAsync(uriBldr.Uri); } void wClient_DownloadStringCompleted (object sender, DownloadStringCompletedEventArgs e) { // ServiceResponse is a text block used to show the runtime response ServiceResponse.Text = e.Result; }

20. WebClient on Custom Runtime Services //Runtime Services Server Code --- Simple ASPX Example protected void Page_Load(object sender, EventArgs e) { this.Page.Response.Clear(); this.Page.Response.Expires = 0; string formattedCustomerNames = string.Empty; SPWeb thisWeb = SPControl.GetContextWeb(Context); SPList itemList = thisWeb.Lists["Customers"]; foreach (SPListItem customer in itemList.Items) { formattedCustomerNames += customer.ID.ToString() + ": " + customer["Title"].ToString() + "\n"; } thisWeb.Dispose(); this.Page.Response.Write(formattedCustomerNames); }

24. Adapter on SharePoint Web Services Advantages/Disadvantages Advantages No cross-domain issues Otherwise, no real advantages over pattern #1 Disadvantages SharePoint functionality is limited to the operations supported by the built-in Web services Slower than pattern #2 Roughly equivalent to pattern #1 in terms of performance Calling SharePoint Web Services from JavaScript is not impossible, but it's not easy Significantly more development effort required on the client: Calling the adapter is simple but developing the adapter is much more complex
