Hide labels for markers in a cluster (AKA FeatureReduction) when clustered

I have some markers with labels attached to them and I am trying to hide their labels when they get clustered.

When the cluster explodes (disables automatically because of zooming in) I need to see the labels like so:

But when clustered, I want it to turn into:

Rather than:

My markers and clusters are stored in the MapView's GraphicsOverlays list.

Thanks in advance

Hi Kaju!

Thanks for your post. This is definitely not expected behaviour.

Is there any chance you could share your data so we can try to reproduce it?

If the data isn't sensitive you can drag and drop the file just below these comments or you can email me directly at tdraeseke@esri.com

Thanks!

Trevor

This should all be supported, but I maybe saw on another post that you've implemented your own clustering logic?

Here's some guides and samples to help using in house clustering with feature reduction, for which labeling is supported:

Thanks!

Thanks for the response!

After some more digging around, I found that the issue was the following code executing every time the user zoomed in:

That for each loop was causing the labels to enable themselves - I'm not sure what purpose it serves but that's been resolved.

Thanks for your help!
