Agenda

•Why Silverlight?•SharePoint Integration▫Linking Projects▫Hosting in SharePoint▫Using Web Services▫Debugging



What’s SharePoint?

• I am not a SharePoint Expert…▫…Some of the Techniques Here May Be

Hacky…▫Goal is to show how it *can* work ▫So you can apply it to your exceptional

SharePoint Skills



SharePoint



Why Silverlight in SharePoint

•Leave to SharePoint (and Web) What They Do Well▫Silverlight for Islands of Content▫Where Graphics and Interactivity Helps▫Don’t Overuse it



Using Silverlight in WebPart Project•Can Create Silverlight in Same Solution▫No Official Linking▫Must Do Manually

Post-Build, Shared File, MSBuild▫Add XAP to WebPart XML file for Deployment



Using Silverlight in WebPart Project•WebPart.xml▫May be better as separate module

<?xml version="1.0" encoding="utf-8"?><Elements Id="..." xmlns="..." > <Module Name="WebParts" List="113" Url="_catalogs/wp"> <File Path="SilverlightTaskViewer.webpart" Url="SilverlightTaskViewer.webpart" Type="GhostableInLibrary" /> <File Path="SilverlightTasksWidget.xap" Url="SilverlightTasksWidget.xap" Type="GhostableInLibrary" /> </Module></Elements>

Hosting in SharePoint

•WebPart Can Create HTML Code▫LiteralControl and ObjectTag

public class SilverlightTaskViewer : WebPart {

protected override void CreateChildControls() { base.CreateChildControls(); string hostTag = @"<object ...></object>";

// Put the Object Tag the control collection LiteralControl slObj = new LiteralControl(hostTag); Controls.Add(slObj); }}



Hosting in SharePoint (2)

•Browser Cache a Problem▫SPUtility.MakeBrowserCacheSafeLayoutsUrl()

Can help but must be in a template to work



Hosting in SharePoint (3)

•WebPart Can Create HTML Code▫Can Use Silverlight control and ScriptManager▫But why?



DemoShowing Silverlight in WebPart



Using SharePoint Web Services•Creating ServiceReferences to SP “Just

Works”▫http://<Machine>/_vti_bin/Lists.asmx▫http://<Machine>/_vti_bin/Alerts.asmx▫Etc.



Using SharePoint Web Services (2)•Data Returned is Typically XML▫Must Use Projection to Shape for DataBinding

XElement tasks = e.Results;

var qry = from i in e.Result.Descendants(rowName) select new Task() { Title = i.Attribute("ows_Title").Value, Priority = i.Attribute("ows_Priority").Value, Status = i.Attribute("ows_Status").Value, };

theList.ItemsSource = qry.ToList();

Debug Considerations

•Pain Points with Debugging the Silverlight Code▫Browser Cache Need Invalidated to Debug▫“Run with Debugging” Only Works Locally

Remote Debugging Silverlight is not trivial Attach To Process Works Well

▫Cross Domain May Be An Issue Too.
