DataTable row grouping. Getting the Microsoft JScript runtime error

[mysliwy]

I am trying to add the datatable row grouping where the .rowGrouping takes the first column and group the row accordingly. Here is my code so far:\[code\]$(document).ready(function () {var oResultGrid = $("[id$='gvReportData']");if (fixEmptyDataRow(oResultGrid)) {var oTable = oResultGrid.dataTable({"bPaginate": false,"bFilter": false,"bInfo": false}).rowGrouping();}else {oResultGrid.dataTable({"sPaginationType": "full_numbers","aaSorting": [[1, 'asc']]}).rowGrouping();\[/code\]When I run the code, I keep getting this error. Any help is greatly appreciated. Thanks.0x800a01b6 - Microsoft JScript runtime error: Object doesn't support this property or method
