  Hi jsshivalik,

  Please modify your code like below:

  public JsonResult List()
          {
              return Json(new { data = usrDB.GetAllUser()}, JsonRequestBehavior.AllowGet);
          }

  You need to make this format so that the datatable can receive the data.

  Best Regard,

  Yang Shen
