DBTreeGrid auto collapsed on update

[nimarufa]

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.

Version 1.50.0.1480 Complete

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)
        }
    });
}

3. ExtEvents -> function store.nodeappend

function store.nodeappend(sender, node, index, eOpts)
{
    if (this.grid.expandedNodes && this.grid.expandedNodes.indexOf(node.data.id)!=-1) {
        if (node.parentNode.data.expanded) { 
            node.expand()
        } else {
            node.data.expanded = true
        } 
        
    }
}

Hi,

and what about when I reopen the query? I want to see the same opened nodes. It is possible?

Need to think about storing this value either in a cookie or on the server side...
