问题:

When I have no rows returned, our jqGrid pager says Page 1 of NaN.

The JSON returned is:

{"page":"1","records":"0","total":"1"}

Why is NaN listed?

Update: We only seem to have this issue when we use loadonce:true.

Here's the source code:

  $("#list").jqGrid({
    url:'NoData.json',
    datatype: 'json',
    mtype: 'GET',
    colNames:['Product', 'Type'],
    colModel :[
      {name:'product', index:'product', width:80},
      {name:'type', index:'type', width:55, align:'right'},
    ],
    pager: '#pager',
    rowNum:20,
    viewrecords: true ,
    caption: 'Positions',
    height: '460',
    loadonce:true,          
    hidegrid: false         
  });

Update 2: What seems to work is the JSON below - is this right?

{"page":0,"records":0,"total":0,"rows":[]}

Something is wrong in the definition of your jqGrid. Look at the simple example of jqGrid filled with your JSON data. You will see "No records to view" ar other text from $.jgrid.defaults.emptyrecords defined in grid.locale-XX.js (grid.locale-en.js for example).

If you will continue to have problem you should append your question with the code of the jqGrid having the described problem.
