jQuery Grid Plugin - jqGrid

Fantastic tool, thanks! I have been reading, and re-reading the manual and I don't understand how to configure the grid such that when I submit an add/edit, the modal dialog will close.

I have the grid configured to launch on ready, as follows:

      $(function() {
        $('#list2').jqGrid({
            url: 'list.php',
            datatype: 'xml',
            colNames: ['Name','URL','Phone','Email'],
            ...
            editurl:'edit.php'
          }).navGrid('#pager2', {add:true,edit:true,del:true}
        );

How do I tell the grid to close the add/edit dialog when done? I tried this (following the function above), but it did not like what I wrote:

$('#list2').editGridRow(rowId, {closeAfterEdit:true});
