Woah .. i c.
So it wont work with Remote model.
Why i want remote model functionalities coz the parents alone will be >
600K rows , childerns are not much only around 3-5 each (i am doing an
email analyzer , children are attachment of each emails
.I want to load datas just the way Remote Data Model loads (When scrolling
down to specified block size).
so , currently there is no such TreeGrid functionalities , is there any in
the work?
Thanks Darrell .
