  1. July 13-14, 2011 ArcGIS API for Microsoft Silverlight – Advanced Topics Morten Nielsen (@sharpgis) Rex Hansen (@rex_hansen)

  2. Agenda • Introductions and Overview • Map and layer optimization • MVVM • WebMaps • API Highlights

  3. Map and layer optimization • Define spatial reference instead of waiting for first layer • Responsible use of graphics • Resolution and scale dependency • Selections with dynamic layers • Simplify symbols • Clustering • Generalize • Limit attributes • DrawMode = OnDemand

  4. Demo: Map and Layer Optimization

  5. MVVM • MVVM: Model-View-ViewModel. • Separate Design, Data and Logic. • Model: User info, Data, Application state, etc. • View: Visual Controls, Buttons, Map, Menus etc. • ViewModel: The “glue” (ie. logic) that ties the view and model together. • MVVM is not a framework but a “design pattern”. • However there are various libraries that provides helper classes. Ex: MvvmLight, PRISM, Caliburn.Micro…

  6. Demo: MVVM

  7. WebMaps • “Map on the web” • Author and share • ArcGIS Online • On-premise portal • ESRI.ArcGIS.Client.WebMap.dll • Document class to load by id or JSON • Returns Map control and attached properties • Map notes = graphics layer • Popups = Map tips, data templates • Get raw JSON from GetMapCompletedEventArgs.DocumentValues

  8. Demo: WebMaps

  9. API highlights • ArcGIS JSON • FeatureLayer, FeatureSet, Renderer, Symbol • Client-side spatial operations • Intersection • Projections • Proxy page • Debugging • Concurrent requests • “Extensions”

  10. Demo • Spatial Operations • ArcGIS JSON • Proxy • Debugging • Concurrent queries • Extensions
