        var ordercollection = masterListService.GetSelectedorders(locationIdOfLoginUser, saleOrderIds, orderIds);
        return View(ordercollection);

    }

Answer 1

The data has to match the "shape" expected. You are passing a single object (with 2 properties) but it is expecting a list (ie JSON array).

You should change your post instead to pass an array:

data: passresult: [{ saleorderIdList: JSON.stringify(saleorder_id),
      orderIdList:JSON.stringify(order_id) }],

If that fails, just as a test, change your action to this and see if it is hit (for your existing data):

public ActionResult PrintPreview(MasterListDTO passresult)
