Programatically expand nodes in on-demand TreeGrid

Hi,
I'm using SmartGWT LGPL 2.4 and don't know how to achieve the following:

I have a databound TreeGrid where I programatically want to expand down to and select some leaf node in the tree that may not have been retrieved from the server yet due to on-demand loading (large tree).
I do have all the IDs/parentIDs for the tree nodes from leaf up to root so in theory I have all info to fetch all the TreeNode involved.

I have tried something like the below pseudocode but does not seem to work. I suppose one should also wait for the expand code to asynchronously returning the child dataset before trying to expand the next level.

for (id = rootid; !isLeaf(id); id = childOf(id)) {
  
  ListGridRecord gridRecord = treeGrid.getTree().findById(id);
              
   if (gridRecord != null) {
       treeGrid.expandRecord(gridRecord);
   }
}

Any ideas?

Hi Haiko,

You should do as follows:

TreeNode node = treeGrid.getTree().findById(treeNodeId);

// open node if it is closed
navTree.getTree().openFolders(treeGrid.getTree().getParents(node));

Hello ,

I read the java doc for treegrid databing but i can't put this mecanism in my Application :the reason is I have a large tree with 15000 employee and I wan to read the parent node in the first loading of the tree and after when i open the parent node i will watch the leaf node of that node and not for the all tree.

I attach my code source to help .

Hi Martin00001 ,

It is working in pages of 75 records by default, see this sample.
