Controller
public ActionResult GridData (string sidx, string sord, int page, int rows)
{
int pageIndex = Convert.ToInt32(page) - 1;
int pageSize = rows;
int totalRecords = db.VOC_CUSTODIAN.Count();
int totalPages = (int)Math.Ceiling((float)totalRecords / (float)pageSize);
var jsonData = new
{
total = totalPages,
page = page,
records = totalRecords,
rows = (from custo in db.VOC_CUSTODIAN.AsEnumerable()
select new
{
id = custo.Idx,
cell = new string []
{
custo.StaffId,
custo.Branch,
custo.UniqueId,
custo.Name,
custo.Role,
("<a href='"+ #Url.Action("Details", "Custodian") +"/"+ custo.Idx+ "'>DETAILS</a>"),
("<a href='"+ #Url.Action("Edit", "Custodian") +"/"+ custo.Idx+ "'>EDIT</a>"),
("<a href='"+ #Url.Action("Delete", "Custodian") +"/"+ custo.Idx+ "'>DELETE</a>")
}
}).ToArray()
};
return Json(jsonData, JsonRequestBehavior.AllowGet);
}

Your view should not handle the logic, your Controller Action should. You should be able to do something like this with Roles.InUserInRole:
if (!Roles.IsUserInRole(User.Identity.Name, "Managers"))
{
jsonData.total = 1;
jsonData.page = 1;
jsonData.records = 1;
jsonData.rows = jsonData.rows.Where(x => x.id = currentUserId).ToArray()
}
return Json(jsonData, JsonRequestBehavior.AllowGet);
