}

Here are the events we are using. Basically, we are trying to pull an item we attached to the map data and present it in a popup. This works find for point data and mostly fine for polyline data, but the events do not fire for polygon data.

I tried different settings for ContentHitTestMode on the UltraGeographicMap control, but none seemed to work for polygon data. I did notice that if that property is set to Computational, then polyline data stopped working.

Thanks for your help.

Hello Charles, 

Thank you for following up. I've reproduced and isolated the behavior with SeriesMouseLeftButtonUp. I've logged a development issue (# 260269) with our developers to investigate this further and opened a private case ( CAS-199686-C3N9S2 ) to provide you with further updates regarding our investigation. You may visit the case from the support activities section > In development tab from your account. 

As a workaround you may use SeriesMouseLeftButtonDown. Also I didn't see any issues with the enter/leave series events. They don't seem to exhibit any problems with our samples. I will update you within the case to investigate this further. 

If you have any additional questions please use the case as well. Thanks.
