Does anyone know of a good way to display hierarchical data with columns?
It has to be virtualizing, as it must be able to handle several million records.
It should also be multi-select, most treeview controls are not.
Winforms preferred, but will ElementHost WPF if necessary.

I'm not quite clear what you mean about hierarchical data with columns, can you clarify? One possibility is the new WPF DataGrid. Depending on the functionality you're looking for it may be what you're looking for.

The bits for datagrid are available on codeplex: http://www.codeplex.com/wpf/Release/ProjectReleases.aspx?ReleaseId=14963
