Hi Antti,
Using the query task to query against my feature service, I am able to retrieve a FeatureSet collection that contains all the features that match my query, but from this point I am not able to do anything with them.
My goal is to delete the features returned by my query, but I am not able to get them into a FeatureLayer so that I can edit. If I add the results to a feature layer, and then delete them from the feature layer, no edits are registered, as the feature layer is in the same state as before I started.
Do you have any advice I might try to accomplish my goal of deleting the features from the feature service without first adding them to a map control?
Much appreciated
Patric
