27619:Renso Hollhumer;41:Annette Roulette;27546:Christopher Hollhumer;27625:Tom Adams

  var allContacts = $.ajax({ url: $('#ajaxListAllAccountContactNamesUrl').val() + '/' + $('fieldset#AccountDetails #Id').val(), async: false, success: function(data, result) { if (!result) alert('Failure to retrieve the Contacts.'); } }).responseText;

    $('#list')
        .jqGrid({
            url: listURL,
            postData: ajaxData,
            async: true,
            datatype: “json”,
            colNames: ['Id', 'Contact'],
            colModel: [
                { name: 'Id', index: '', hidden: true, hidedlg: true },
                { name: 'Contact', index: 'Contact', edittype: "select", editoptions: { value: allContacts } },
            ],

Very important, tjhe ajax call to get in this example the contacts must be set to async: false otherwise the grid will render before the data is returned and nt data will show up on your select.

Later, if after the grid gas been rendered you want to change the selection of the SELECT, use the editOptions property via the setColProp on the loadComplete event or other external event to set the contacts:

$('#list').setColProp('Contact', {editOptions: {value: newListOfContacts} });
