Popup for visible layers only?

KarenEllett — Mon, 21 May 2012 13:38:39 GMT

Is there a way to constrain the popup behavior to only layers that are currently checked as visible? Right now, with on-click popup, even layers that are turned off show up in the results.

Does anyone have any knowledge or guidance on this? I've looked everywhere I can think to look, but I can't figure out if this is customizeable or not.

Hi Karen,

We've verified that this is a bug: Pop-ups display when a sub-layer is unchecked. If the parent map service layer is unchecked, then popups do not appear for any layers within the service.

Thanks! I know you can't give any solid answers yet, but do you think this is a bug that will be fixed with the next release?

Yes, unfortunately I don't know at this time, but it's definitely in our bug queue.

I've created a work around for this issue, I simply reset the value of the IdentifyLayerIds collection when the layer visibility changes. As the Identify behavior only returns results from visible layers, it does require that the web services have all of their sub-layers turned on by default in order work properly. Layer/Sub-layer visibility should to be set in the viewer configuration.

ps You will need to add a reference to ESRI.ArcGIS.Mapping.Core which can be found in Viewer.xap

Jeff,

This is great! Especially for a Viewer which contains a lot of layers with subgroups.

thanks,

Elisabeth
