I have seen earlier post here where the developer wanted such function but your reply was that is not possible. Why can't we have this?
Take this scenario:
> I have two trees, both Load On Demand, using Web Service - so when expanded, the nodes are loaded.
> Based on selection in one tree, I need to check nodes in another tree via javascript only (not server side)
> Now, the node that I want to check may not exist in the another tree, because its parent is not expanded and its not loaded
> I can expand parent node first, but then I have to wait till the response is back, and then only I can find the node to check it;
> If I can turn the parent node to Intermediate state then I don't have to load all children via javascript and don't have to wait. This can be done via set_checkedState if it was available
> If not possible, then how do I know when the child nodes are loaded via web-service? is there some event that gets generated?
Let me know if you have some approach in mind for this scenario.
