You can define your GraphicCollection in Xaml under UserControl.Resources as such:   <esri:GraphicCollection x:Key="MyGraphics" /> and then create the binding to Graphics this way:   <esri:GraphicsLayer ID="MyGraphicsLayer"                                 Graphics="{Binding Source={StaticResource MyGraphics}}"> Any changes to your GraphicCollection should affect the Graphics in your GraphicsLayer.

Tim Heuer at Microsoft posts a lot of good samples and tutorials. This one is specific to databinding: http://timheuer.com/blog/articles/silverlight-get-started-part-4-binding-data.aspx In your earlier question, I think you need to understand the syntax used in Binding. For example, when no Path property is defined, it must be implied so {Binding Visible, Mode=TwoWay} is the same as {Binding Path=Visible, Mode=TwoWay}. And when no ElementName property is defined, the DataContext is assumed to have already been set. So {Binding Visible, Mode=TwoWay}, means grab the Visible property of the Layer, since the ListBox is already bound to the Map's Layers. This is WPF DataBinding Cheat sheet, most of them apply to Silverlight so you might want to learn the syntax and when they are useful:http://www.nbdtech.com/Blog/archive/2009/02/02/wpf-xaml-data-binding-cheat-sheet.aspx Good luck!

The new graphic must be checked if it intersects with a certain other shape. We created a webservice for this functionality. So the check is no problem. But if the check say "editing on this place is not allowed" I would like to cancel the edit. Do you perform this check prior to calling SaveEdits? If the issue is with adding new graphics, I assume you use the TemplatePicker within the EditorWidget. You need to get this from EditorWidgetStyle (use Expression Blend "EditTemplate"). Get the Editors from their DataContext and on the EditCompleted event, check that when an Add occurs or EditVertices occurs, they intersect the shape (as you mentioned in your requirements), if the new graphic fails this test, do not call SaveEdits.

There is no sample for this yet because the SL/WPF API does not expose the Editor's ActiveEditor property, which you might need to achieve this.  You can however, listen to the Editor's EditorActivated and EditCompleted events to know when the Editor is active and which EditAction has completed. Or you can also listen to the button's Click and IsEnabledChanged events. Either way, in the event handler, you can change your image or button's appearance accordingly. Jennifer ... View more

Does it mean that the FeatureLayer will use the symbol it uses in ArcMap? Yes, if the rest endpoint created by your published service contains a renderer, this will be picked up by the SL/WPF API.  For example: http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/BloomfieldHillsMichigan/LandusePlanning/FeatureServer/0 This FeatureLayer includes a Unique Value Renderer (see Drawing Info).

When using SL Toolkit Theme, does it put your map inside a ScrollViewer? This is not supported, since the scrollviewer intercepts the mouse events needed for panning. Jennifer ... View more

I don't see anything wrong with your code-behind. It looks similar to the sample. Maybe let VS create the Eventhandler for you by doing locatorTask += and then tab, see if this is any different to the LocatorTask_AddressToLocationsCompleted() you have. If this does not work, can you also share your XAML code? Jennifer ... View more

You can set the layer's AutoSave property to false. Get the Editors from the EditorWidget's and TemplatePicker's DataContext. Note that these two editors are separate, you can get the TemplatePicker using Expression Blend "Edit Template" on EditorWidget. When you have both editors, you can listen to their EditCompleted event, perform the necessary checks for the graphics and call the save here. Kindly see the code below for guide.         public MainPage()         {             InitializeComponent();             Editor editorForWidget = this.MyEditorWidget.DataContext as Editor;                        if(editorForWidget != null)                 editorForWidget.EditCompleted += new EventHandler<Editor.EditEventArgs>(editorForWidget_EditCompleted);         }         private void editorForWidget_EditCompleted(object sender, Editor.EditEventArgs e)         {             foreach (var edits in e.Edits)             {                 e.Action // check action (EditVertices, Reshape, Cut, Select,..)                 edits.Graphic // perform the check for graphic                 // if check succeeds, save the edits                 if (edits.Layer is FeatureLayer)                     (edits.Layer as FeatureLayer).SaveEdits();             }         } Jennifer ...

Oh you are right, the Renderer is new to ArcGIS 10. I was going to point you to this http://sampleserver3.arcgisonline.com/ArcGIS/rest/services Notice that there is a "DrawingInfo" section that defines the renderer. This is the only ArcGIS 9.3.1 that I know about http://sampleserver1.arcgisonline.com/ArcGIS/rest/services Jennifer ... View more

I believe the sample was written to show how you can define a renderer using the API. If your FeatureLayer already has a renderer, you do not need to overwrite it. Jennifer ... View more

Sure, you can iterate thru your Map.Layers and check for each layer's visible property and pass in the layer's Url to the IdentifyTask if layer is visible. Jennifer ... View more

How about adding this to the graphic's attributes (IDictionary<string, object>)? You are looking for a temporary storage for the ContextMenu, right? Jennifer ... View more

Which version of API for SL/WPF are you using? You can learn more about v2.0 from here (see Concepts tab also) http://help.arcgis.com/en/webapi/silverlight/samples/start.htm In the code you provided, I don't think you need to have your tooltip bound to the grid. Are you able to go to your map layer's URL through IE? At minimum, I think the following code should be sufficient to display your map. <Grid x:Name="LayoutRoot" Background="White"> <esri:Map x:Name="map">   <esri:ArcGISTiledMapServiceLayer ID="SustainMapService" Url="http://webgis/ArcGISUWM/rest/services/SustainMap/MapServer"/> </esri:Map> </Grid> Jennifer ...

You can set the Visibility property of the layer and before adding the legend, check if the layer is Visible. Jennifer ... View more
