    [CLOSED] [1.4] Treepanel Filtering issue

    Hi,

    On the treepanel sample http://examples1.ext.net/#/TreePanel/Advanced/Filter/ , when i type in "xre" on the triggerfield, the XRender gets filtered but its children are not showing up (XRender is expanded).

    Isnt it supposed to be collapsed and when expanded, it should show the Advanced, Basic, UserControl child nodes? What's the work-around for this?

    Thanks much!

    Hi,

    There is just an example of possible filtering.

    Please try the main filtering:
    http://examples1.ext.net

    It expands the nodes you need, but it should be implemented manually, it's not a built-in behavior.

    Please look at the Examples Explorer sources:
    <Ext.NET sources root>/Ext.Net.Examples/resources/main.js
    Search for "filter".

    Hi Daniil,

    Thanks for the tip. Please mark as solved.

    For anyone who may need a solution for this, here's mine, just tweak it to meet your requirements:
    var filterTree = function (el, e) {
                        var tree = TreePanel1,
                    text = this.getRawValue();
    
    
                        tree.clearFilter();
    
    
                        if (Ext.isEmpty(text, false)) {
                            return;
                        }
    
    
                        if (e.getKey() === Ext.EventObject.ESC) {
                            clearFilter();
                        } else {
                            var re = new RegExp(".*" + text + ".*", "i");
    
    
                            tree.filterBy(function (node) {
                                var match = re.test(node.text)
    
    
                                if (!match)
                                    match = checkParent(node, re);
    
    
                                return match;
    
    
    
    
    
    
                            });
                        }
                    };
    
                var clearFilter = function () {
                        var field = triggerFilter,
                    tree = treepanelEvidencePackages;
    
    
                        field.setValue("");
                        tree.clearFilter();
                        tree.getRootNode().collapseChildNodes(true);
                        tree.getRootNode().ensureVisible();
                    };
    
    
                    var checkParent = function (node, re) {
                        var result = false;
                        var parent = node.parentNode;
    
    
                        while (parent != undefined) {
    
    
                            if (re.test(parent.text)) {
    
    
                                result = true;
                                break;
                            }
                            parent = parent.parentNode;
                        };
                        
                        return result;
    
    
                    };
    Regards,
    Marcelo
