Has I still don't know how to add a expand icon on a treeview, I use the Onclick event to check if I need to load the children node of a treeview... 

 

 

if (parentId != 0) {

 parentNode = tree.findNodeByValue(parentId);

}

 

 
... Code to Add Nodes 

tree.commitChanges(); 

if (parentId != 0) {

 parentNode.set_expanded();

}

 

 
Result is great.... The node expands... But it collapses back !

Hi Peter Ryckaert,

Could you please try calling the set_expanded method over the node object with bool value (for expand - true, e.g. node.set_expanded(true))?
I think this is what's missing here.

Hope this is going to help you!
