I'm trying to populate a load on demand MultiSelectTree control with root level data, then when the user clicks and expands the node, the data is requested and loaded. The only example I see of something similar is the lazy loading. My scenario is for a filter control that may not get used by the user so I wanted to load a minimal set of data and then request more if needed.
I have tried it with flat and hierarchal data. Also, validated my data variable that the control is bound to is getting updated but the control never refreshes with the new child nodes. I tried to refresh the data using the NodeExpand event and also the fetchChildren method (fetches for all nodes which is not what I want)
Can this be done? Just want to make sure before I waste any more time on it.
Thanks
