How do I set a treeGrid to expand all nodes programmatically?

[blevinson]

I know I can set the SectionStackSection to setExpanded(true) but I don't see that anywhere in the treeGrid.

Use TreeGrid.getData().openAll()

Use TreeGrid.getData().openAll()
I'm using a TreeGrid with a client only DataSource and this method works for me, i hope it helps

treeGrid.fetchData(new Criteria(),new DSCallback() {

	@Override
	public void execute(DSResponse response, Object rawData, DSRequest request) {
		treeGrid.getData().openAll();
	}
});

passing null object as Criteria or just a new Criteria() produce the same results. I think you must call this method from DSCallback's execute method because fetchData runs asynchronously. If you do it somewhere else, just make sure your data is in place.

Cheers!
