Hi,
Please suggest how to implement Load on demand in a Ultra Win Tree(Trial version 8.1). I need to bind a collection of Parent objects to the Tree initially. Then upon expansion of the Parent nodes(that would be created), i require to fill the empty collections within the Parent objects with the Child object. My parent object contains a collection of child objects. I have figured out That it can be done using the BeforeExpand Event. But i am facing some strange behavior as some times the child nodes shows up correctly, and at other times, the child object gets populated in the collection but are not reflected in the Tree.
I have read in the forum, that member "ProkopivIgor" have faced similar issues.

Using the BeforeExpand event is the right way to go. But I'm afraid I can't guess why it's not working for you without any information about what the actual problem is or what your implementation is doing.
Perhaps the best thing to do is for you to create a small sample project demonstrating the problem and Submit an incident to Infragistics Developer Support.
