Repeater自定义分页排序.....
分页加排序的存储过程:
- --得到总记录数
- 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
- --分页加排序
- if exists(select 1 from sys.objects where name = 'GetProductsByPage' and type = 'P')
- drop proc GetProductsByPage
- go
- CREATE PROCEDURE GetProductsByPage
- @sortExpression nvarchar(100),
- @pageNumber int,
- @pageSize int
- AS
- -- 确保指定了 @sortExpression
- IF LEN(@sortExpression) = 0
- SET @sortExpression = 'ProductID'
- DECLARE @sql nvarchar(4000)
- set @sql = 'select ProductID, ProductName, SupplierID, CategoryID, QuantityPerUnit, UnitPrice, UnitsInStock, UnitsOnOrder, ReorderLevel, Discontinued
- from (select row_number() Over (order by ' + @sortExpression + ') as row,ProductID, ProductName, SupplierID, CategoryID, QuantityPerUnit, UnitPrice, UnitsInStock, UnitsOnOrder, ReorderLevel, Discontinued
- from products) as ProductsWithRowNumber
- where row between ' + convert(varchar, (@pageNumber - 1) * @pageSize + 1) + ' and ' + convert(varchar, @pageNumber * @pageSize)
- exec sp_executesql @sql
- go
- --exec GetProductsByPage 'productid desc', 1, 10
- --exec GetProductsByPage 'ProductName desc',5, 10
- --exec GetProductsByPage '', 1, 10
无法忍受如此垃圾的编辑器,页面代码转换的一塌糊涂,所以Repeater标记部分用图片代替
- <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
