                        ],
              pager: jQuery('#pager'),
  
              autowidth: true,

              onSelectRow: function(ids) {
                  if (ids != null) {
                      var data = $("#list").getRowData(ids);
                      jQuery("#DetailList").setGridParam({ url: "/Master/DetailGridData/" + data.Id, page: 1, datatype: 'json' })
             .setCaption("&lt;b&gt;Details of Master : " + data.Descripcion+"&lt;/b&gt;")
             .trigger('reloadGrid');
                  }
              }
