Virtualization not working as intended

[nielwestover]

Virtualization should work as simply as this, but it does not. Replace MultiSelectTreeView with TreeView in the code below and virtualization works seamlessly. What would it take to make this work? Thanks!

<Controls:MultiSelectTreeView
	x:Name="_treeView"
	Grid.Row="2"
	ItemsSource="{Binding VariableTree.Nodes}"
	VirtualizingStackPanel.IsVirtualizing="True">
	<Controls:MultiSelectTreeView.ItemsPanel>
		<ItemsPanelTemplate>
			<VirtualizingStackPanel />
		</ItemsPanelTemplate>
	</Controls:MultiSelectTreeView.ItemsPanel>
</Controls:MultiSelectTreeView>

Virtualisation is a biest. And certainly anything but simple. (I did that in another project.) It's probably not possible with the current design of this. I replaced it with something else in a big application because of this. MultiSelectTreeView is not a TreeView, it's built from scratch. And I just based upon another project's work and haven't worked on this in a very long time. So don't expect a solution here.

Thanks for taking the time to reply. I figured it was probably more trouble than it's worth. Also, I understand this project is not currently being worked on, but I put the issue here for others if they feel so inclined (worked before).
