checkchange event problem

[DundeeParticipant]

Hi,

i have that kind of code :

$("#cblSitesUpload").on('checkChange', function (event) {
            var item=event.args.item;
            if (item.value == 0 && !item.checked) {
                $("#cblSitesUpload").jqxDropDownList('checkAll');
                $("#cblSitesUpload").jqxDropDownList('uncheckIndex',0);
            }
        });

This dropdown list regroup a list of item..and when i unselect the “All item” checkbox..i need to checkall item except the the one i just uncheck……but when i test this code..it’s fire error like this “item is undefined”

What i do wrong??

I readed on this forum that checkall fire event for all event..but if it’s work for the first one i uncheck..why this error..

Hi Dundee,

The problem is that you do check/uncheck in a ‘checkChange’ event. ‘checkAll’ will raise ‘checkChange’ and so do ‘uncheckIndex’. Implementation with ‘checkAll’ is already available – http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxgrid/customfiltering.htm?arctic
