boring
Boring!
  • I want some data in there
  • Common Method
    • Web Service
  • We’re in SharePoint, lets look at that first
connections in sharepoint
Connections in SharePoint
  • Use Part to Part communication to provide a value
  • Place it in Silverlight using InitParams
    • HTMLish way to pass params to Silverlight
external data
External Data
  • Finally, the Web Service example!
  • Options
    • Web Client
    • WCF Service
    • RIA Services (Additional Addon)
well that was easy
Well that was easy
  • If only it was always like that!
  • Digg is special, it has a client policy xml file
    • Twitter doesn’t
  • Origin Policy
    • Limits you to calling things on the same server as YOUR XAP
    • Same Port and Everything
    • Silverlight respects Flash client policy files
getting around origin
Getting around Origin
  • Common Approaches
    • Proxy Web Service
      • Tunnel whatever request you want through a custom web service
      • Requires you to maintain another mapping layer
      • Hard to protect against rogue internet people
    • RIA Services
      • Very cool, lets you pass your domain objects around
      • Dynamically writes web service proxy code for you
      • Currently in Preview, not ‘Production’
      • Silverlight 3 Only
    • Trickery
oooh i like trickery
Oooh, I like trickery
  • Toolbox
    • We’ve got a control that’s running that can hit web services and databases
    • Silverlight can execute javascript and has access to the web page
  • The Plan
    • Make our control do the dirty work and dump it into the DOM
    • Silverlight parses and interprets the results
