/ Filters out the overlays that match the names for user overlays So I think it could be something in GeoCollection not working properly. I tested it out with a normal ObservableCollection instead for my Overlays and Layers and it worked fine. It “duplicates” the item in the TreeView. I noticed that when calling the Layers.MoveUp and Layers.MoveDown functions, the TreeView does not update properly. For populating custom object in tree, you just need to create template for your object. You just need to tell him which field will be shown in item. I’m using a TreeView that’s bound to my Map’s Overlay + Layers. You can directly add your object as a TreeViewItem in the tree and WPF gives respect to your objects and display it as you want.
