I think that the most important feature that have to be included
in the next release must be the ability to keep the Virtual TreeView
Synchronized with the other controls in the same form.
Yes may we have a lot of Rows (Currency Managers) but i think
that this feature completes the design of Virtual Tree.
If we dont have this feature our UserInterafce is INCOMPLETE.
It is not too difficult to code this feature and is EXTREMELY IMPORTANT
TO BUILD A GOOD USER INTERFACE

The problem with providing full two way support for CurrencyManagers (ie allowing Virtual Tree to drive selection AND be driven by an external control) is that each child list would require its own CurrencyManager. But virtual tree does not even request the child lists until they are required. This means there would be no way to drive Virtual Tree selection via the CurrencyManager mechanism to a row in a child list that was not already displayed.

We could however potentially implement one way support for CurrencyManagers that would allow VirtualTree to drive selection of other controls. As this is still likely to carry some overhead during selection we would probably make it optional. Would this be sufficient for your needs?

But If we enforce virtual tree to display AND Select this Binding List when
we choose it from another control?
The best way to check it is to put side by side two
virtual trees and make tests
I write an application which demands all the lists being loaded
in memory when runs (and not reside in the database and loaded when this being asked)
why not to implement currency managers for this circumstance?
Can I load all the nodes of a virtual tree view ?
if i have only 100 nodes why not to implement currency managers?

This one way driving is in the near future or not?
it is important to know because we are writing an application
and we need this feature

Well it won't make it into the first release of Version 3.0 which we are finalizing now and about to start testing on. So version 3.1 would be the likely release. This will probably be at least two months away.
