Add Captured Multipoint Geometry to Feature Set?

Jessica Gould
I have a workflow where I'm ultimately passing a FeatureSet to a Geoprocessing Service.  I first get my FeatureSet with a query task.  But then I have a Display Capture Geometry activity to capture multipoint geometry where the user would like to add features.  

 

I can't figure out how to then add that multipoint geometry, as individual features, to my existing FeatureSet.  I thought to try to loop through the captured geometry and add each geometry as a mappoint to a collection of mappoints, but I can't figure that out. Any hints or ideas are appreciated!

    I may be a bit rusty here but I think that you want to iterate your multipoint, turn each point into an object of the "Graphic" class, and then add that graphic to the featureset's .Features property, which IIRC is itself merely a Collection(Of Graphic).  Make sure that you give your features the data that they need in their fields, its probably eaiest for you to do it during your enumeration.

    Thank you so much.  Can you provide guidance on how I can iterate through my multipoint?  I've tried several different TypeArguments and they all give me an error.

    I think you could do something like this (paste the contents of the next post in a new workflow with File > New > From Clipboard

    There are no words to describe how grateful I am to you, Nico!!!  This worked perfectly for me, I would have never ever come up with it. Thank you so much again.

    Hi Nico.

    Could you put here the contents of the post that has been deleted, i think. I need the same guidance as Jessica to iterate through my multipoint, and i don't know how to do it.

    Thank you.

    Is this helpful at all?  I can also send the xml if needed

    Hi Jessica. Is it possible to have the xaml (xml) file?

    Thank you so much. It's been very useful.

    Thanks as well. Found this useful to iterate through map points (capture coordinate pairs) in a multipoint geometry
