Is it possible to use both SmartRendering and Tree [+/-] construction in TreeGrid component?

Hello!

I just bought pro version and have first problem:
I need to use both: SmartRendering to dinamic loading grid (<rows pos="(...)">) and Tree feature to make some grups (<rows parent="(...)">) but I can't get it work.

Please, post some example.

SmartRendering mode availalble for plain grids only ( in case of tree-grid the order of row changed by each open-close operation so prediction is not usable )
For TreeGrid you can try to use dynamical loading

In such mode tree loads content of sub-branches by additional AJAX request - this allows to show unlimited hierarchy.
