You can subscribe to "BeginSaveEdits" event of the FeatureLayer; in "BeginEditEventArgs" parameter of the handler check for "Adds", "Deletes", and "Updates", i.e. e.Adds, e.Deletes, e.Updates respectively.
Thanks Ali That is what I am currently doing, but I must confess I rather not do that bookkeeping myself especially since the collection obviously must be kept by the featurelayer (or its parent). The reason I need this, is to do custom validation of the edits before they are saved. I imagine that that is quite a common task. Is there any plans to open the API to get hold of that collection?
There is no way to get to a collection of 'edits'. I suggest you do the validation of the edit before the edit itself is pushed to the feature layer. What type of validation are you trying to perform?
Validations we do: First of all: different users can only edit in their own areas. On top of that, some feature category�??s must be placed inside other features category�??s etc (this could be done by topology rules on the server, but for usability reasons we do want to validate this on the client)
The editor is only meant for simple editing scenarios. For more advanced custom scenarios like this, I suggest you use the Draw class instead and handle the user input/validation. On draw completed, simply perform your validations then add the feature to the FeatureLayer. Ie myFeatureLayer.Graphics.Add(newlyAddedGraphic), and the feature will automatically get pushed back to the server.
