I also have some kind of similar requirement .I want to bind my EditorWidget Control to feature layer from a feature service having threee editable feature layers
which is already present in ArcGIS Webpart in Sharepoint.The requirement is by giving some identifiable name of each layer from user input editor widget will be binded to one layer at a time.
We can go with MapApplication.Current.Selected Layer but this is not the case ,user will be providing layer name and our code will activate editor widget on that particular layer .
Can you please help me with some reply?
