jQuery Grid Plugin - jqGrid

Hello,

I have the following configuration:

    jQuery("#list47").jqGrid({
        data: mydata,
        datatype: "local",
        height: 300,
        width: 670,
        rowNum: 10,
        scroll: 1,
        viewrecords: true,
        shrinkToFit: false,
        colNames: ['Inv No', 'Date', 'Client', 'Amount', 'Tax', 'Total', 'Notes'],
        colModel: [
               { name: 'id', index: 'id', width: 60, sorttype: "int" },
               { name: 'invdate', index: 'invdate', width: 90, sorttype: "date", formatter: "date" },
               { name: 'name', index: 'name', width: 200 },
               { name: 'amount', index: 'amount', width: 80, align: "right", sorttype: "float", formatter: "number" },
               { name: 'tax', index: 'tax', width: 80, align: "right", sorttype: "float" },
               { name: 'total', index: 'total', width: 80, align: "right", sorttype: "float" },
               { name: 'note', index: 'note', width: 150, sortable: false }
           ],
        pager: "#plist47",
        rowNum:15,
        rowTotal: 50,
        scroll: 1,
        loadonce:true,
        rownumbers: true,
        rownumWidth: 40,
        gridview: true,
        viewrecords: true,
        caption: "Manipulating Array Data"
    });

Is it possible to trigger an event (eg. when a button is clicked) and load the next page rows automatically?

Thanks,

Cornel
