Repeater自定义分页，使用的存储过程如下
--取得总记录数 ifexists(select 1 from sys.objects where name = 'GetProductsCount' and type= 'P' ) drop procGetProductsCount go CREATE PROCEDURE GetProductsCount as select count (*) from products go --使用row_number函数 --SQLServer2005的新特性,它可以将记录根据一定的顺序排列,每条记录和一个等级相关这个等级可以用来作为每条记录的rowindex. ifexists(select 1 from sys.objects where name = 'GetProductsByPage' and type= 'P' ) drop procGetProductsByPage go CREATE PROCEDURE GetProductsByPage @PageNumberint , @PageSizeint AS select ProductID,ProductName,SupplierID,CategoryID,QuantityPerUnit,UnitPrice,UnitsInStock,UnitsOnOrder,ReorderLevel,Discontinued from (select row_number()Over( order by productid) as row,ProductID,ProductName,SupplierID,CategoryID,QuantityPerUnit,UnitPrice,UnitsInStock,UnitsOnOrder,ReorderLevel,Discontinued from products) as ProductsWithRowNumber where row between (@PageNumber-1)*@PageSize+1 and @PageNumber*@PageSize go --execGetProductsByPage1,10 --execGetProductsByPage5,10
--取得总记录数
if exists(select 1 from sys.objects where name = 'GetProductsCount' and type = 'P')
drop proc GetProductsCount
go
CREATE PROCEDURE GetProductsCount
as
select count(*) from products
go
--使用row_number函数
--SQL Server 2005的新特性,它可以将记录根据一定的顺序排列,每条记录和一个等级相关 这个等级可以用来作为每条记录的row index.
if exists(select 1 from sys.objects where name = 'GetProductsByPage' and type = 'P')
drop proc GetProductsByPage
go
CREATE PROCEDURE GetProductsByPage
@PageNumber int,
@PageSize int
AS
select ProductID, ProductName, SupplierID, CategoryID, QuantityPerUnit, UnitPrice, UnitsInStock, UnitsOnOrder, ReorderLevel, Discontinued
from
(select row_number() Over (order by productid) as row,ProductID, ProductName, SupplierID, CategoryID, QuantityPerUnit, UnitPrice, UnitsInStock, UnitsOnOrder, ReorderLevel, Discontinued
from products) as ProductsWithRowNumber
where row between (@PageNumber - 1) * @PageSize + 1 and @PageNumber * @PageSize
go
--exec GetProductsByPage 1, 10
--exec GetProductsByPage 5, 10
页面代码如下:
< asp:linkbutton id = "lbtnFirst" runat = "server" commandname = "First" oncommand = "lbtnPage_Command" > | < </ asp:linkbutton > < asp:linkbutton id = "lbtnPrevious" runat = "server" commandname = "Previous" oncommand = "lbtnPage_Command" > < < </ asp:linkbutton > < asp:label id = "lblMessage" runat = "server" > < asp:linkbutton id = "lbtnNext" runat = "server" commandname = "Next" oncommand = "lbtnPage_Command" > > > </ asp:linkbutton > < asp:linkbutton id = "lbtnLast" runat = "server" commandname = "Last" oncommand = "lbtnPage_Command" > > | </ asp:linkbutton > 转到第< asp:dropdownlist id = "dropPage" runat = "server" autopostback = "True" onselectedindexchanged = "dropPage_SelectedIndexChanged" > </ asp:dropdownlist > 页 </ asp:label >
<linkbutton id="lbtnFirst" runat="server" commandname="First" oncommand="lbtnPage_Command">|<</linkbutton><linkbutton id="lbtnPrevious" runat="server" commandname="Previous" oncommand="lbtnPage_Command"><<</linkbutton><linkbutton id="lbtnNext" runat="server" commandname="Next" oncommand="lbtnPage_Command">>></linkbutton><linkbutton id="lbtnLast" runat="server" commandname="Last" oncommand="lbtnPage_Command">>|</linkbutton>
转到第<dropdownlist id="dropPage" runat="server" autopostback="True" onselectedindexchanged="dropPage_SelectedIndexChanged"></dropdownlist>页
