title: how to reset jqgrid after refreshing its data
body: <p>I'm refreshing jqgrid with this script:</p>
  
  <pre><code>$('#btnRefresh').click(function () {
     $.ajax({
        type : "GET",
        url: "${pageContext.request.contextPath}/General/ProvinceLoadGrid.json",
        success: function (data) {
             if (data != null) {
                 jQuery('#dataTable').jqGrid('clearGridData')
                       .jqGrid('setGridParam', {data: data, page: 1})
                       .trigger('reloadGrid');
             }
        }
     });
  )};
  </code></pre>
  
  <p>I have configured jqgrid to save selected rows after moving through pages.
  this script triggers reload grid to reload data, but this produces a problem.
  the problem is when I select first row in the page 1, (when each page has 10 records)
  the first record on the second page (11th record) is selected too. also the record on the 3rd page is selected too (21st record) etc ...
  all of this happens after reloadGrid. the jqgrid is saving my selection on each page correctly, but after reload grid this problem occurs.</p>
  
  <p>How can I manage to solve this?</p>
