[CLOSED] Remote Load of Nodes and configured filters

[macap]

Hello,

I have a problem with the combination of using filters to a tree and loading childnodes of a node remotely.
When I apply a filter my filter works fine on every node which is already loaded.

But the filter is not applied to the nodes which I load after I set up the filter.
Is there a property somewhere which I need to set to apply my configured filter to every node (not only the already loaded nodes)?

Hi,

I guess your code is based on this example?
https://examples1.ext.net/#/TreePanel/Advanced/Filter/

I can't see any way to apply the filter which is not loaded yet.

But you should be able to apply filters when new nodes are added to a tree. Please use TreePanel's Append listener.

<Append Handler="someCodeToApplyFilters" Buffer="200" />

Hi Daniil,

thanks for the answer. And yes, that was my basic example I was referring to.

I also thought about applying the same filter after every append event.

But AFAIK the filter always applied to the whole try and not only the just loaded node-subset.
Is that true?

If yes... is there a way to apply a filter to a just loaded node and its childnodes?

Hi,

Just pass required node as startNode field in the second argument (config object)

tree.filterBy(function (node) {
     return re.test(node.text);
}, {startNode : requiredNode});

It looks I misunderstood your requirement.

Yes, the filter is applied for all tree by default. But you can set a startNode to filter.

As you can see in the Ext.Net sources the piece of filterBy method looks:

filterBy : function (fn, config) {
    config = config || {};
    var startNode = config.startNode || this.root;

So, to set a startNode:

tree.filterBy(someFunction(), { startNode: someNode})

That works fine. Thank you!
