为DataGrid自定义分页添加自定义导航和分页信息 以下文字资料是由(全榜网网www.cha138.com)小编为大家搜集整理后发布的内容,让我们赶快一起来看一下吧!
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(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 * / @PageSize)
DECLARE @SQLSTR NVARCHAR( )
IF @PageIndex = OR @PageCount <=
SET @SQLSTR =N SELECT TOP +STR( @PageSize )+
CustomerID CompanyName Address Phone FROM Customers ORDER BY CustomerID DESC
ELSE IF @PageIndex = @PageCount
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
