# VirtualTreeView
A virtualizing TreeView for .NET Framezork 4.6.2, .NET 6 and .NET 8
## How to use it
It is available as a [NuGet package](https://www.nuget.org/packages/VirtualTreeView/).
The source code includes a demonstration application, where both modes (content and binding) are showed, side-by-side to traditional `TreeView` control.
### The treeview itself
It works exactly as the original `TreeView` (with a lot of missing features...):
```xaml
<Setter Property="IsExpanded" Value="{Binding MyIsExpanded, Mode=TwoWay}" />
```
### The treeview item
If you move from an existing treeView, you'll need to copy/paste your `TreeViewItem` style and adapt it to `vtv:TreeViewItem` (usually no change is required, except removing the hierarchical part, which is generated when the control converts the tree to a list).
### What does work
Currently it has only the features I needed (which is showing items and let them live); all contributors are welcome. The goal is to have a complete and extensible tree view.
* With binding, `INotifyCollectionChanged` fully works, so you can dynamically change content by adding or removing elements at any point of the hierarchy.
### What does not
* With binding, `INotifyPropertyChanged` **does not work at all**, since the binding is partly simulated (because the view items are not generated).
### How to contribute
Fork it, update it, and submit your pull requests.
