想法是這樣的：使用bindingNavigator+存儲過程實現DataGridView的分頁功能，其中包含簡單的查詢。
存儲過程如下：
--創建分頁查詢存儲過程(含輸出參數，輸入參數（含搜索功能）)
use HotelDB
if exists(select * from sys.procedures where name='pro_getGuestRecord')
drop procedure pro_getGuestRecord
gocreate procedure pro_getGuestRecord
@pageSize int,
@pageIndex int,
@beginTime datetime,
@endTime datetime,
@ResideID int,
@RecordCount int output
as
begin
declare @sqlStr0 nvarchar(max);
set @sqlStr0 = 'SELECT @RecordCount=count(a.GuestID)
FROM GuestRecord AS a INNER JOIN
Room AS b ON a.RoomID = b.RoomID INNER JOIN
ResideState AS e ON a.ResideID = e.ResideID INNER JOIN
RoomType AS d ON b.RoomTypeID = d.TypeID INNER JOIN
RoomState AS c ON b.RoomStateID = c.RoomStateID'
set @sqlStr0 +=' WHERE (a.ResideDate BETWEEN ''' + CAST(@beginTime as nvarchar)+ ''' AND '''+ CAST(@endTime as nvarchar)+ ''')';
if(@ResideID <> 0)
begin
set @sqlStr0 += ' AND (e.ResideID = '+CAST(@ResideID AS nvarchar)+')';
end
declare @sqlStr1 varchar(max);
set @sqlStr1 = 'select * from(
select row_number() over(order by a.GuestID asc) as num,
a.GuestID, a.GuestName, a.ResideDate, a.Reposit, a.LeaveDate, a.TotalMoney, b.RoomID, d.TypeName,
c.RoomStateName, b.RoomStateID
FROM GuestRecord AS a INNER JOIN Room AS b ON a.RoomID = b.RoomID
INNER JOIN ResideState AS e ON a.ResideID = e.ResideID
INNER JOIN RoomType AS d ON b.RoomTypeID = d.TypeID
INNER JOIN RoomState AS c ON b.RoomStateID = c.RoomStateID'
set @sqlStr1 +=' WHERE (a.ResideDate BETWEEN ''' + CAST(@beginTime as varchar)+ ''' AND '''+ CAST(@endTime as nvarchar)+ ''')';
if(@ResideID <> 0)
begin
set @sqlStr1 += ' AND (e.ResideID = '+CAST(@ResideID AS nvarchar)+')';
end
set @sqlStr1 +=') as GuestRecordInfo';
set @sqlStr1 +=' where num between '+CAST(@pageSize as nvarchar)+'*('+CAST(@pageIndex as nvarchar)+'-1)+1 and '+CAST(@pageSize as nvarchar)+'*'+CAST(@pageIndex as nvarchar)+'';
execute sp_executesql @sqlStr0,N'@RecordCount int output',@RecordCount output
--execute sp_executesql @sqlStr1
exec(@sqlStr1);
end
winform界面設計如下：
主要的CS代碼如下：
//每頁顯示記錄數
private int pageSize = 2;
//當前頁碼
private int pageIndex = 1;
//總頁數
private int pageCount = 0;
//總記錄數
private int RecordCount = 0;//默認顯示當天的全部入住狀態的數據。
//開始時間
private DateTime beginTime = DateTime.Now.Date;
//截止時間
private DateTime endTime = DateTime.Now.Date.AddDays(1);
//入住狀態ID
private int ResideID = 0;private void Form_Load(object sender, EventArgs e)
{
Bind();//綁定DataGridView數據。

//設置分頁顯示數據

//設置下拉選擇可選內容
