我試圖在C＃windows應用程序中實現DataGridView的分頁。基本上我有一個簡單的DataGridView，它由數據庫中的存儲過程填充，並從另一個存儲過程獲取全部記錄。分頁無法正確使用DataGridView？
我還在網格中添加了三個按鈕，它們引用了其他三種形式，並將它們作爲參數發送TicketID（網格中的第0列）。
現在當網格被加載時，它完美地工作（所有3個按鈕在參數中成功發送TicketID），但是每當我點擊分頁控件（第一，上一個，下一個，最後一個）時，我添加的3個按鈕不會功能正常。我的意思是，不是發送TicketID（列0）作爲參數，而是發送列的「ButtonName（.Text of DataGridView按鈕）」。
我似乎無法弄清楚問題是什麼，如果有人能幫助我，我會非常感激。

總記錄的存儲過程：
ALTER PROCEDURE [dbo].[getTotalNo]
AS
BEGIN
select count(*) total from tblTicketDetail where status = 1
END
ShowRecords的存儲過程：
ALTER PROCEDURE [dbo].[showRecord]
@pagesize int,
@skip int
AS
BEGIN
SELECT TOP (@pagesize) * FROM tblTicketDetail WHERE TicketID NOT IN (SELECT TOP (@Skip) TicketID FROM tblTicketDetail)
END
在將問題應用於問題時請注意標籤。 ['paging']（http://stackoverflow.com/tags/paging/info）指的是*完全*不同的東西。 –
另外，我找不到任何sql代碼 – Alexander
