There is a nice sample at http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#ToolkitFeatureDataForm which shows how to allow a user to edit the underlying attribute data. I can make this work with my own data up to the point where the editing table opens. At that point the data is visible but not editable. What do I need to do to allow editng of my data? Is there something in the service itself, or perhaps some server permissions that need set?
OK, so as I read that info it says "All data must be from a single ArcSDE geodatabase." Implied meaning that it will not work with a shapefile. So that leads me to wanting to implement the project using a related table rather than the actual attribute table. I think all I need to do this is the ability to click a feature on the map and capture the click event with the FID of the feature. I can then create my own query and bring up the needed record in a .NET datagrid. Is there a sample around that would show me how to do that?
