DBTreeGrid auto collapsed on update
Hi, I've got one problem - after update data in TreeGrid the grid is auto collapsed.
I need only update data and keep opened nodes open and closed nodes close.
I'm attaching a sample.
Way to repoduce:
1. Tap "Expand" or open some nodes.
2. Tap Update
The thee will close all nodes automatically.
Please help to solve it.

Can you try this approach ?!
UniDBTreeGrid -> ClientEvents ->
1. UniEvents -> function beforeInit:
function beforeInit(sender, config)
{
sender.expandedNodes=[];
}
2. ExtEvents -> function store.beforeload
function store.beforeload(store, operation, eOpts)
{
var me=this.grid;
me.expandedNodes=[];
me.getRootNode().cascadeBy(function(node) {
if (node.data.expanded) {
me.expandedNodes.push(node.data.id)
}
});
}
