I already went through that articles and if i set the Load Ahead Level property to 2, It works only upto 2 levels.

I have more than 9 level of tree structure.  If we setup Load Ahead Level property more than 2 it causes performance issue as well.

Below solution works for me and it is work around for Tree View Control:-

• Keep Load Ahead Level property to 1 (As default setting) or set to none.
• On Tree Change Event add below Advance Condition to check ID of parent node if it not equal then only execute logic(rules) that you want.
• Add Data Label(Flag) on View or Form and set Value as 0.
• Add below condition in Changed Event:-
• When Tree is Changed
•    If an Advanced Condition is True (Tree is not empty & Flag is not equal to ID) See image Tree.png
•           Execute Your Logic Rules.
•           Set Flag = Tree Current ID (View -->Control-->Tree-->Data Source-->ID) See image Tree1.png

So on changed event it will not loop mutiple time for same ID of your clickable parent node.
