Update/reset all features

I've got workflows for updating single features using and assign statement for resultFeatureSet.Features(0).Attributes("FieldName") and following it up with an UpdateFeatures. That works great for updating single features, but how do I update values for an entire featureset?

 

I'm building a demo app to show how door knockers could canvas an area house by house, and I want there to be a tool in the I want to menu that resets all of the houses' status attribute values.

  Use a ForEach activity. Set the type to be <Graphic>.

   

  Loop through each Graphic in the FeatureSet setting graphic.Attributes("Yo") = "Dawg" in an assign activity.

   

  Let us know if that works.

  Hi John, would you mind sharing your workflow that updates a single feature that you referenced in the beginning of your post? I'm having trouble with the UpdateFeatures activity.

  Here are the bare bones pieces I use to update a single feature. In practice, these steps are usually cooked into a more complicated flowchart, but the basic process of querying the layer, updating the values using Assign activities, and then using Update Features is the same.

  How about updating the each feature while still in the loop - it looks like it is not possible to do so and that UpdateFeatures only works when called outsite the loop ?

  Do you have a use case for that situation you can share?
