DataTable RowGrouping Not Grouping Error
<p>I am using DataTable 1.9 and the RowGrouping pluging. The IQueryable collection being binded to the datatable is not sorted or grouped before the databinding event. When I used the following code</p>

<pre><code>        var oResultGrid = $("[id$='gvReportData']");

        if (fixEmptyDataRow(oResultGrid)) {
            var oTable = oResultGrid.dataTable({
                "bPaginate": false,
                "bFilter": false,
                "bInfo": false
            }).rowGrouping({
                bExpandableGrouping: true,
                iGroupingColumnIndex: 2

            });
        }
        else {
            oResultGrid.dataTable({
                "sPaginationType": "full_numbers",
                "aaSorting": [[1, 'asc']]
            }).rowGrouping({
                bExpandableGrouping: true, 
                iGroupingColumnIndex: 2
            });
        }
</code></pre>

<p>I can see that the rowgrouping takes the 2nd column as the grouping field. I see the gray grouping header on top of each row/record, but the common row in term of the column are not grouped. I only see the grouping field in gray header on top of each row but they are not group under the grouping field, therefore, no + expandable or collapsible function. </p>

<p>Been spinning for hours on this. Any help is greatly appreciated.</p>
