How To make dynamic Tree from TUniTreeView node expand?

[rgreat]

Usually i catch onNodeExpand method and add subnodes there.

But TUniTreeView does not have such method.

I figured i nee to use TUniTreeView.ClientEvents.ExtEvents.

 

After some blind man tries i produced this weird code:

function itemexpand(sender, eOpts)
{
  for (var i=0;i<sender.stores.length;i++) {
    if (sender.stores[i].hasOwnProperty("nm")) {
      ajaxRequest(sender.stores[i],'expand',['internalId='+sender.internalId]);
      break;
    }
  }
}

But it does not work consistently.

 

Now I'm kind of lost on what to do.

sender.internalId does not always corresponds with TTreeNode.AbsoluteIndex;
