View Full Version : Ext JS very slow check/uncheck nodes in tree since 4.2 version

4 Mar 2014, 7:56 AM
I use cascadeBy function and record.set('checked', checked); to check/uncheck child nodes in Ext JS treepanel.
In 4.0.7 and 4.1 version of EXT JS all works fast. But when I upgrade my project to 4.2 version this operation use more then 4 times more time.

Here is example:


checkchange: function (record, checked, opts) {

var i=0;
var start=new Date;
record.cascadeBy(function(e) {

e.set('checked', checked);
var stop = new Date;
alert(i +'items '+ (stop-start)+'ms');


if i use version 4.2.0 I have 132 items rendered in 2677ms

if I use version 4.1.0 I have 132 items rendered in 735ms

if I use version 4.1.1 I have 132 items rendered in 645ms

How can I improve treepanel speed ?
