How to retrieve result from an EditOperation

OlivierDamanet

Hi,

I would like to use the EditOperation to cut or split a polyline feature at a given MapPoint (snapped to the Polyline). I see I can use either .Cut or .Split method, but the EditOperation does only return a boolean whether it's successful.

How can I get the new feature from the Cut operation? I need to udpate some attributes after cut on both the old and new feature...

Thanks,

The only way to do this at the moment is through the edit events, either editcompleted or the row events, picking up the create and modify feature.

Here's an example of using row events in a cut sketch tool.

In the future there will be more ways to monitor changes in an edit session and attribute rules to script actions on certain edit functions like cut/split.
