asp.net 自定义分页控件

这个分页的主要是用了四个linkbutton按纽的事件，然后利用后台传递的条件调用分页处理的方法，在这个控件中可以点击表头排序，并且可以突出显示关键字等。

显示的页面:

调用的函数:

 public DataTable SelectPageFiles(string WhereCondition, int PageIndex, int PageCount, string OrderCondition)

分页存储过程的参数:

--根据条件显示相应的记录，并分页。
ALTER PROC SelectPageFiles
@WhereCondition nvarchar(500),  --查询条件
@PageIndex int,        --页号
@PageCount int,        --每页的记录数
@OrderCondition varchar(50) --排序条件
as.....

调用控件声明:

<%@ register tagprefix="MyTag" tagname="MyDataList" src="~/DataShow.ascx" %>

定义控件:

 <MyTag:MyDataList id="MyDataList1" runat="server"></MyTag:MyDataList>      

调用分页控件:

this.MyDataList1.BindDataSource(WhereCondition, this.keyword.Text.Trim());
