在treepanel网格中缓慢复选框更新

Question

这是我正在做的更新treegrid中的所有子节点。更新子节点会导致刷新每行的视图，这似乎会减慢检查复选框的更新过程。

我尝试过使用ext.suspendLayout，component.suspendlayout，component.suspendEvents但没有性能提升。当检查父节点时，需要检查大约80个子节点。完成此操作大约需要4秒钟。

//code for checkbox that is recursively updated.
return Ext.create("Ext.form.field.Checkbox", {
            checked: checked,
            record: record,
            name: "Enabled",
            fieldCls: record.data.nodeLevel != 2 ? (checked == 1 ? "checkBlue" : (checked == 2 ? "checkBlack" : '')) : "",
            hideable: false,
            xtype: 'checkbox',
            name: "TreeCheckStatus",




            handler: function (checkbox, checked) {





                page.gridPanel.suspendEvents();

                Ext.defer(function () { record.set("TreeCheckStatus", getTriStatevalue(record)); }, 1);

//recursive function to update all child notes records
                updateAllChild(record, getTriStatevalue(record));

                page.gridPanel.resumeEvents(true);

            }
        });


    }




    //recursive method to update all the nodes
      function updateAllChild(record, value) {


        if (record.hasChildNodes()) {
            // page.gridPanel.suspendLayouts();
            var childParentStatus = true;
            Ext.each(record.childNodes, function (rec) {
                rec.beginEdit();






                rec.set("TreeCheckStatus", value);

                updateAllChild(rec, value);


                rec.endEdit();

            });


        }
