How can I laod the tree grid with all its node expanded.
I tried calling expandAll() function before rendering the tree grid on the page, but it does not seem to works.
All the items/nodes are in collpase mode although I use expandAll() whle laoding the tree grid.
The loading is async., so expand command need to be executed from after-loading callback
grid.load(url,function(){
grid.expandAll();
});
