为DataGrid自定义分页添加自定义导航和分页信息
日期：2012-05-02 浏览次数：20492 次
在上一篇文章中我讲到了对DataGrid实行自定义分页，这可以避免为了显示一页数据而获取整个数据记录集，从而提高分页效率，不过使用的导航还是DataGrid自带的数字连接或简单的上一页，下一页，而且看不到总页数、总记录数之类的信息。下面就为他增加我们所需要的部分。
先来看看修改后的分页显示，截图如下：
（图一）
使用的数据源同上一篇文章（Asp.net中DataGrid控件的自定义分页）相同，都是访问Northwind库，为了独立开来这里还是把存储过程列了一下，
CREATE PROCEDURE [GetCustomersDataPage]
@PageIndex INT,
@PageSize INT,
@RecordCount INT OUT,
@PageCount INT OUT
AS
SELECT @RecordCount = COUNT(*) FROM Customers
SET @PageCount = CEILING(@RecordCount * 1.0 / @PageSize)
DECLARE @SQLSTR NVARCHAR(1000)
IF @PageIndex = 0 OR @PageCount <= 1
SET @SQLSTR =N'SELECT TOP '+STR( @PageSize )+
' CustomerID, CompanyName,Address,Phone FROM Customers ORDER BY CustomerID DESC
ELSE IF @PageIndex = @PageCount - 1
SET @SQLSTR =N' SELECT * FROM ( SELECT TOP '+STR( @RecordCount - @PageSize * @PageIndex )+
' CustomerID, CompanyName,Address,Phone FROM Customers ORDER BY CustomerID ASC ) TempTable ORDER BY CustomerID DESC'
ELSE
SET @SQLSTR =N' SELECT TOP '+STR( @PageSize )+' * FROM ( SELECT TOP '+STR( @RecordCount - @PageSize * @PageIndex )+
' CustomerID, CompanyName,Address,Phone FROM Customers ORDER BY CustomerID ASC ) TempTable ORDER BY CustomerID DESC'
EXEC (@SQLSTR)
GO
下面就就把代码贴了一下，
Aspx文件代码如下：
