Map extent changed event

MaxMax2 — Thu, 23 Nov 2017 12:03:00 GMT

Is there an event when visible extent of the current map changed? I want to track such changes to update some values in my add-in. Or maybe there is a workaround for this task?

I've found that event. It is ViewerExtentChanged from the ArcGIS.Desktop.Internal.Mapping. It is possible to attach handler to this event with the Subscribe method.

Hi,

You can use the MapViewCameraChangedEvent for this. http://pro.arcgis.com/en/pro-app/sdk/api-reference/index.html#topic12830.html

The ViewExtentChanged event is in an internal namespace - they could change anytime. So not recommended to use anything from a Pro API Internal namespace.

Also, there are a couple of samples in the arcgis-pro-sdk-community-samples that uses the MapViewCameraChangedEvent.

Thanks
