Layer Doesn't Render Until Queried

JamieBurmeister — Tue, 28 Jan 2025 04:44:38 GMT

Hi,

I'm encountering an issue where features in my layer don't render unless they're queried for. Unfortunately, this layer is secured and belongs to a third party, so demonstrating the issue is not something we can offer publicly, but we can provide credentials to ESRI developers that want to look into the issue. I've attached a video of the issue, and the repro project can be found here: https://github.com/AceCoderLaura/ArcGISRuntimeBugDemos. The bug is listed on the main menu as "Feature Not Rendered Bug"

Thanks.

Hi,

thanks for sharing the details and the repro project. This seems like an unusual issue. Since the layer is secured and third-party, it might be worth checking if there are any restrictions or specific settings on their end affecting rendering.

I tried reproducing it with data we have but I was able to get the layer rendered without need of querying.

In the meantime, have you tried testing with other layers to rule out client-side issues?

Hopefully, we can assist further with the credentials provided.

Hi Jamie,

After deeper investigation, it appears that the problem originates from the hosted Feature Service, which is causing the error. This does not seem to require a patch or fix on the SDK side.

I have reported this bug to the appropriate team for further review. In the meantime, as a workaround, you can disable the tiling mode on the Feature Layer.

siteLayer.TilingMode = FeatureTilingMode.Disabled;

This will ensure that features render correctly without requiring explicit queries.

Please let me know if you have any further questions or need assistance implementing this workaround.

Thank you for reporting this.
