Question

我有以下代码：

模型

public int ManufactureID { get; set; }

public string Manufacture { get; set; }

public string ManufactureDescription { get; set; }

public bool IsActive { get; set; }

控制器

public ActionResult ManufactureIndex(string manufacture = "")
{
    ManufactureRepository ManufactureRepo = new ManufactureRepository();
    ModelState.Clear();
    ViewBag.sManufacture = manufacture;
    return View(ManufactureRepo.ManufactureGetAll(manufacture));
}

存储库

private SqlConnection con;
//To Handle connection related activities
private void Connection()
{
    con = new SqlConnection(ConfigurationManager.ConnectionStrings["ITPCNMSCon"].ToString());
}

//To view employee details with generic list
public List<Manufactures> ManufactureGetAll(string manufacture = "")
{
    Connection();
    List<Manufactures> EmpList = new List<Manufactures>();
    SqlCommand com = new SqlCommand("_spManufactureGet", con)
    {
        CommandType = CommandType.StoredProcedure
    };
    if (string.IsNullOrEmpty(manufacture))
    {
        com.Parameters.AddWithValue("@Manufacture", DBNull.Value);
    }
    else
    {
        com.Parameters.AddWithValue("@Manufacture", manufacture);
    }
    SqlDataAdapter da = new SqlDataAdapter(com);
    DataTable dt = new DataTable();
    con.Open();
    da.Fill(dt);
    con.Close();

    //Bind EmpModel generic list using LINQ 
    EmpList = (from DataRow dr in dt.Rows

               select new Manufactures()
               {
                   ManufactureID = Convert.ToInt32(dr["ManufactureId"]),
                   Manufacture = Convert.ToString(dr["Manufacture"]),
                   ManufactureDescription = Convert.ToString(dr["ManufactureDescription"]),
                   IsActive = Convert.ToBoolean(dr["IsActive"])
               }).ToList();
    return EmpList;
}

存储过程

SELECT      *
FROM        _Manufacture
WHERE       Manufacture = ISNULL(@Manufacture,Manufacture)
ORDER BY    Manufacture

我的问题是，我想使用sql连接在视图上提供排序和分页。我怎样才能做到这一点？请指教。

谢谢。

Answer 1

 int pageSize = 10;
 int skip = 0;
 int recordsTotal = 0;

pagesize 是您要在网格中显示的记录数，跳过是选择记录的起点， recordsTotal 网格中的记录总数。

  recordsTotal = EmpList.Count();
  EmpList= EmpList.Skip(skip).Take(pageSize).ToList();

Answer 2

您需要传递您要为每个请求获取的页码和号码以及记录数。

@PageNumber int
@Records int


Declare @StartingPoint int, @EndingPoint int
Set @StartingPoint = ((@PageNumber -1 ) * @Records)+1
Set @EndingPoint = @PageNumber  * @Records
Select * from (
  Select Dense_Rank() over(order by <PK>) Order,* from <Table>
)TempRecord where [Order]>= @StartingPoint  and [Order]<=@EndingPoint

现在，当您调用此存储过程时，传递PageNumber和Records参数值

当你为PageNumber传递1而为记录时传递10则StartingPoint将为1而EndingPoint将为10，因此你得到10条记录类似于Page 2 StartingPoint将是11而EndingPoint将是20，因此你将获得10条记录。

谢谢你的回答。我有自己的答案。我正在按照下面的教程创建排序和分页。
