Don't show the group

[manzamParticipant]

Hi,
I’m trying to binding, but I don’t show the groups, Why ?

My code :

var source =
{
datatype: “json”,
datafields: [{ name: ‘IdClasificacionDetalle’, type: ‘int’ },
{ name: ‘Nombre’, type: ‘string’ },
{ name: ‘group’, type: ‘string’ }],
id: ‘IdClasificacionDetalle’,
url: ‘/Usuario/ListaClasificacionDetalle’
};
var dataAdapter = new $.jqx.dataAdapter(source, {
formatData: function (data) {
$.extend(data, {
idEmpresa: _idEmpresa
});
return data;
}
});
dataAdapter.dataBind();
// Create a jqxListBox
$(“#listboxClasificacionDetalle”).jqxListBox({
source: dataAdapter, displayMember: “Nombre”, valueMember: “IdClasificacionDetalle”, width: “100%”, height: 250, checkboxes: true
});
$(“#listboxClasificacionDetalle”).on(‘checkChange’, function (event) {
var args = event.args;
if (args) {
// index represents the item’s index.
var index = args.index;
var item = args.item;
// get item’s label and value.
var label = item.label;
var value = item.value;
alert(“label: ” + label);
}
});

Hello manzam,

If you want to show data from ‘group’ datafield you should set ‘displayMember’ or ‘valueMember’ to ‘group’. You can find more information about how to Bind the ListBox to JSON data on Getting Started.

Thanks for reply, but I need is show the Group and Name at the same time like de example “Categories”

Hello manzam,

Setting categories (groups) when loading the listbox from JSON data is not supported. You can, however, try the approach specified in the following post as a workaround: http://www.jqwidgets.com/community/topic/combobox-list-categories/#post-49874.
