Jannifer, thanks for your help. AutoSave is set for my featureLayer. When calling editor's EditCompleted event, the graphic is saved already. I cannot stop save by writing any code in it. ... View more

Thank you DBroux. your suggesion is great. I am not sure how to implement it. You can't save a polygon geometry in an ArcGIS server polyline feature class. So, the only way is you to transform the polygon to the polyline at the client side. I don't know if there is a sample somewhere, but I guess this is doable (using Paths and Rings properties of the geometry). ... View more

My question is whether different spatial references between esri map and my map can cause identify no result? I mean, are different spatial references OK when my layers need to be identified? To test if IdentifyTask failed in your SL application or if empty IdentifyResults was expected, you can use Fidder to see what parameters SL app formed and use the same parameters in your web browser. If the result that you get from the web browser is not identical to the result you get from your application, we may have a problem.  To do this, you can look at this thread, post #14 http://forums.arcgis.com/threads/14730-Area-And-Perimeter. ...

EditorWidget is set up like yours and also set LayerIDs="WCR" which is polygon. I check Freehand checkbox, nothing shows, and I cannot do freehand draw. when I click template picker, just draw polygon not freehand. Does the EditorWidget show the template for that layer?  If no, be sure to specify an ID for that layer. The EditorWidget ignore layers that do not have an ID. The EditorWidget's LayerIDs property is optional but if you have set this, be sure that it includes the ID of the FeatureLayer with Polygon geometry. Also when working with FeatureLayers with Polyline/Polygon geometries, GeometryService property is required.  Below is an example of minimal settings for EditorWidget:                     <esri:EditorWidget Map="{Binding ElementName=MyMap}"                                                                             GeometryServiceUrl="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer"/> At the right-end of the EditorWidget is Add Options button "...", when you click on this and the Add Options popup is shown, check Freehand checkbox. Select a feature type in your polygon layer and begin drawing. ... View more

Thanks Jannier. I got your good ideas. one more left is how to replace data form of adding new feature with my own FeatureDataForm? The FeatureDataForm displayed by the EditorWidget cannot be styled at the moment.  If you wish to use your own customized FeatureDataForm, you will need to customize the EditorWidget default style to replace the DisplayAttribute button with your own button that will display your own FeatureDataForm instance. You can refer to this sample on how to update the properties for the FeatureDataForm: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#ToolkitFeatureDataForm ... View more

Thanks dbroux. I got your first idea. No identify result come out for mapservice layers. IdentifyEventArgs e.IdentifyResults.count=0. I am not sure if different spatial references between esri map and my map caused the problem. No, the identify task is not working with feature layers. As the features are loaded at the client side, you don't need to indentify the features ('Identify' is working with the server). Instead you can use a maptip to display infos about features. It should work with mapservice layers. What is exactly your issue? ... View more

Thank you very much, Ali! the way you provide is great! that is what I am looking for. You can use Expression Blend and right-click on your FeatureDataForm and select "Edit Template" --> "Edit a copy...", then you will get the default control template for your FeatureDataForm. Switch to the XAML view and look for the "CommitButton" button. Jennifer shared a very good URL on how to do the styling in Blend, you can also look into that page. ... View more

Thank you Ali. I am wondering why my xaml code of FeatureDataForm copied from Resource center is just black box:    <esri:FeatureDataForm x:Name="MyFeatureDataForm"   FeatureLayer="{Binding Path=Layers[PointLayer], ElementName=MyMap}"  IsReadOnly="False" LabelPosition="Left" /> How can I convert the code to be style like yours? then I can add the button. ...

Thanks Jennifer. I still cannot add a button to it. the FeatureDataForm is kind of one control, the Apply button cannot be seen,  and my button cannot be inserted into FeatureDataForm. Here's a blog on how you can customize the look and feel of ArcGIS controls http://blogs.esri.com/Dev/blogs/silverlightwpf/archive/2010/05/20/Use-control-templates-to-customize-the-look-and-feel-of-ArcGIS-controls.aspx It's similar steps except you choose FeatureDataForm ...
