Tree Grid Pagenation issue


My tree grid can have two trees and each tree can have their respective child’s (Ex: each tree can have 3 child’s ). so the pagination shows Records for 1 to 8 of 8.Here is the problem i want only pagination for child’s in the tree grid but not root nodes.As records from 1 to 6 of 6.
How to do this stuff?

Unfortunately such feature is not supported.
