2 Introduction 75 minute session minute lecture minutes Q & A following the lecture Who are we? Jian Huang Undral Batsukh Who Wh are you?? We will answer questions at the end Please comlete the session survey!

3 Agenda Samles driven from real world use cases Resolve your questions Insire your ideas Patterns, tis and tricks AJAX SOAP API ArcObjects API Web ADF JavaScrit GrahicsLayer Enhanced functionalities Print

4 1. Current mouse location in Longitude/Latitude Coordinate values under current satial reference? Convert to Long/Lat Technique Techniq Technique: e: Geometry Geometr service, ASP.NET AJAX, Web ADF JavaScrit Library NAD 1983 SPCS California X: Y:

5 2. Modifying Toc content at runtime Toc Nodes are oulated during g The initial call to PreRender Call to Refresh or RenderLegendHtml Technique Technique:: Handle H dl Toc.NodesPoulated T N d P l t d eventt Triggered after the nodes are oulated. Add, modify or remove content from the Toc Changes must be alied each time Toc nodes are oulated Need to exlicitly manage changes you make to Toc content

6 3. Creating and modifying TaskResults contents Can exlicitly y define arent--child node content arent in TaskResults Technique Technique:: Three different result tyes are available: SimleTaskResult DataSet TaskResultNode Use TaskResults.DislayResults to add results Can use context menus in a TaskResults control

7 4. Best ractice for thematic maing Classify y and render features Pre Pre--comuted layers y solution Best erformance solution Predefined, which cannot be changed by users definition Technique Technique:: Change ersective

8 4. Best ractice for thematic maing continued Grahicslayer y solution User interaction Custom renderer Only suorts simle classification Technique T h i Technique: : FeatureGrahics, F t G hi Custom C t renderer d

9 4. Best ractice for thematic maing continued ArcObjects j solution Fully suorts comlicated algorithm Requires much more coding efforts Needs to take care of shallowly stateful changes Technique T h i Technique: : shallowly h ll l stateful t t f l change h managementt ArcGIS Server

10 5. Showing a rogress bar whenever a Web ADF request is issued Indicate to a user that user action is being g rocessed. Technique Technique:: Use PostbackManager Utility control Provides a simle way to issue asynchronous requests Use client tier invokingrequest and requestprocessed events to show a rogress bar

11 6. Converters Link Web Geometry, y, SOAP Value Objects j and ArcObjects COM Objects The most useful ones are: ESRI.ArcGIS.ADF.Web.DataSources.ArcGISServer.Converter.FromAdfGeometry ESRI.ArcGIS.ADF.Web.DataSources.ArcGISServer.Converter.ToAdfGeometry ESRI.ArcGIS.ADF.ArcGISServer.Converter.ValueObjectToComObject ESRI.ArcGIS.ADF.ArcGISServer.Converter.ComObjectToValueObject

12 6. Converters continued Technique Technique:: How to erform geometry oeration via G Geometry t service, i how h to t convertt among different diff t data d t tyes

13 7. Resizing a ma when window resizes The ADF JavaScrit Ma class No Resize When window is resized, ma size is checked via checkmasize Technique Technique:: Handle window resize event to adjust ma size By default ma maintains scale when resized To maintain extent Handle maresized event and set the extent exlicitly Resize

14 8. Adding REST layers through JavaScrit Overlay y REST layers y in Ma control Technique Technique:: Web ADF JavaScrit, ArcGIS Server REST Services

15 9. Layout temlate for the Print Task Customize the layout y and rendering g of the rint task Using temlate files, CSS and JavaScrit A new roerty LayoutTemlateFile is introduced at to define the temlate file

16 10. Creative use cases of Grahicslayer Dynamic y real time GPS osition dislay y Technique Technique:: Client Callback, WebWeb-Tier Grahicslayer Web ADF Grahics

17 10. Creative use cases of Grahicslayer continued Consume third arty y web services Consume Yahoo traffic web service showing real time traffic info Maniulate M i l t client li t grahics hi by b Web W b ADF JavaScrit J S i t Technique Technique:: Client Grahicslayer Web ADF JavaScrit
