Treeview navigation problem after a new added node

[suleymanera]

I am inserting a new node and keeping cursor on new node. I have a sub-form to check whether source data is bookmarked at correct record. It is working correctly. Then I am navigating the treeview object ,sub-form also reflecting correct recordset data till cursor revisit the new added node. When it is happened ,sub-form reflecting a data belongs to first record of the related table file. When I continue to navigate other nodes, It is again working correctly but revisiting the new added node.
When I close and re run the application, sub-form reflecting all the node related data correctly till a new node added.
I need advice to fix the problem.
Thanks in advance.
