I need to pass datatable value as json to angular js only if datatable contains data.So that I can alert the value of datatable in view.

What I have tried:

public DataTable GetChqStatus(decimal chqno)
{
    string sql = "select chqNo,status from tblchqNo where chqNo=@chqno and status='cancelled'";
    SqlParameter[] param = new SqlParameter[]
    {
        new SqlParameter("@chqno", chqno)
    };
    return DBO.GetTable(sql, param, CommandType.Text);
}

public ActionResult getchqStatus(decimal chqno)
       {
           DataTable dt = objemp.WithdrawalBs.GetChqStatus(chqno);
           if (dt.Rows.Count>0)
           {
           return Json(dt, JsonRequestBehavior.AllowGet);
           }


       }

$scope.ChqStatus = function(chqno)
   {
       crudServiceUser.GetChqStatus(chqno).then(function (result) {
           $scope.Cheque = result;

       })

   }
