LayerViewStateChanged Event

MarkCederholm — Fri, 24 Mar 2017 21:36:04 GMT

While ILayerContent and LayerViewStatus are meant to simplify table of contents code, I see a problem in that the LayerViewStateChanged event only fires for layers, not sublayers (e.g. of an ArcGISMapImageLayer). What happens when the visibility of a sublayer changes, but not of the parent layer? Unless I'm missing something, the way I see it, I still need to navigate through and check visibilities of sublayers whenever MapView drawing or navigation completes, in order to update their TOC entries.

[BTW, I'm glad to see the DrawStatusChanged event -- that's been on my wish list since Runtime .NET first came out.]

The LayerViewState applies to the concrete 'Layer' class type, which sublayers are not.

The sublayers should raise INotifyPropertyChanged for properties so for instance the IsVisble property bindings would auto-update.

Also there's already a table-of-contents control in the v100.0.0-beta1 toolkit that has all this implemented

Thanks, I'll check it out.
