Prevent auto expanding

[d.bernaert]

Hello,

I want to prevent the complete expansion of a unidbtreegrid when adding a subitem.

How could that be done?

I add a record to the dataset and just do a post.

Thx,

Dominique

Hello Dominique,

If possible, can you make a simple testcase for reproduce?

Okay,

will do with a memory dataset?

OK.

Hi,

I've created a small sample application.

It's not quite the same problem but it shows what I want.

In this case, there are subtitles in the second title and in the third title.

Click on the second title and add a subtitle to the second title.

You will see that the complete tree view will be collapsed.

I want the second title to remain expanded and the new subtitle selected.

I also don't want the third title to be expanded when adding a subtitle to the second title.

Thx,

Dominique

Hi Dominique,

Thanks for the testcase. I will check.

Hello Dominique,

Sorry for the late reply.

Can you try to use 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 (node && node.data && this.grid.expandedNodes && this.grid.expandedNodes.indexOf(node.data.id)!=-1) {
        if (node.parentNode && node.parentNode.data.expanded) { 
            node.expand()
        } else if (node.parentNode) {
            node.parentNode.expand()
        }                  
    };
}

Make a simple testcase for check.
