Hi,

Thanks,

Hello Aviad,

Let say you have node Entries and subnode SubEntries (recursive to Entries). Attribute IsExpanded is mapped to expanded property of treeNodeType. So you have to iterate and set appropriate status (true to expand or false to collapse) as Valery suggested in early mentioned post.

  private void setNodeStatus(IPrivateXXX.IEntriesNode node, boolean status) {
	for(int i=node.size();i>0;) {
		final IPrivateXXX.IEntriesElement element = node.getEntriesElementAt(--i);
		element.setIsExpanded(status);
		if(element.getIsNode()) {
			setNodeStatus(element.nodeSubEntries(), status);
		}
	}
  }

Best regards, Maksim Rashchynski.

Is there a way to call the event for "collpase all" in the code?

OK, Thanks for this.

But, isn't there an easy way to 'click' on the "Callapse All" icon of the tree in code?

There is a collapse button in tree control, it seems to do exactly the same

However, this functionality is not exposed to code directly.
