.net - Webgrid SelectedLink URL Issue -

i have webgrid. when selecting id column displays partial view further details on item.

it working fine lately strange timestamp has appeared when pressing/highlighting id link;

localhost:xxxxx/page?selectedrow=1&__swhg1234567890 example.

the '&__swhg1234567890' needs removed have no idea why appearing in url , causing the webgrid links not work.

it handled in index.cshtml

var grid = new webgrid(model,         canpage: true,         cansort: true,         rowsperpage: 20,         defaultsort: "projno",         selectionfieldname: "selectedrow",         ajaxupdatecontainerid: "gridcontent");   <div id="gridcontent">     @grid.gethtml(tablestyle: "table",     headerstyle: "head",     alternatingrowstyle: "altrow",     selectedrowstyle: "selectrow",     columns: grid.columns(grid.column("id", "id", format: (item) => item.getselectlink(item.id)),                           grid.column("text", "text", format: (item) => item.text == null ? string.empty : item.text),             grid.column(header: "actions", format: (item) => new htmlstring(html.actionlink("edit", "edit", new { id = item.id }).tostring() + html.actionlink("delete", "delete", new { id = item.id }).tostring()))))  </div>  @{     ims.models.entities.page page= new ims.models.entities.page(); }  @if (grid.hasselection) {      page= (ims.models.entities.page)grid.rows[grid.selectedindex].value;          <div id="deschead">          detail goes here         </div>         <br /> 

any appreciated.

it turns out ajax problem. removing unused 'ajaxupdatecontainerid' parameter corrected problem.
