源代码

PostBack方式分页时，当页导航元素之一被单击或用户手工输入页索引提交时发生，Url方式分页时，页面第一次加载时发生。

C# 语法：

public event EventHandler PageChanged;

备注：

该事件被引发时，AspNetPager 已完成分页操作。

示例：

下面的示例显示如何为PageChanged事件指定和编写事件处理程序，在该事件处理程序中重新绑定Repeater上显示的数据：
      
<%@ Register Assembly="AspNetPager" Namespace="Wuqi.Webdiyer" TagPrefix="webdiyer" %>
<%@Import NameSpace="System.Data"%>
<%@Import NameSpace="System.Data.SqlClient"%>
<script runat="server" Language="C#">
void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            int totalOrders = (int)SqlHelper.ExecuteScalar(CommandType.StoredProcedure, "P_GetOrderNumber");
            AspNetPager1.RecordCount = totalOrders;
            bindData();
        }
    }

 void bindData()
    {
        Repeater1.DataSource = SqlHelper.ExecuteReader(CommandType.StoredProcedure,"P_GetPagedOrders2005",
            new SqlParameter("@startIndex", AspNetPager1.StartRecordIndex),
            new SqlParameter("@pageSize", AspNetPager1.PageSize));
        Repeater1.DataBind();
    }

 void AspNetPager1_PageChanged(object src, EventArgs e)
    {
        bindData();
    }
</script>

<BODY>
<form runat="server">
  <webdiyer:AspNetPager ID="AspNetPager1" runat="server" Width="100%" HorizontalAlign="right" PageSize="8" OnPageChanged="AspNetPager1_PageChanged">
        </webdiyer:AspNetPager>

        </HeaderTemplate>
        <ItemTemplate>
        <tr style="background-color:#FAF3DC">
        <td><%#DataBinder.Eval(Container.DataItem,"orderid")%></td>
        <td><%#DataBinder.Eval(Container.DataItem,"orderdate","{0:d}")%></td>
        <td><%#DataBinder.Eval(Container.DataItem, "companyname")%></td>
        <td><%#DataBinder.Eval(Container.DataItem,"customerid")%></td>
        <td><%#DataBinder.Eval(Container.DataItem,"employeename")%></td>
        </tr>

		<FooterTemplate>

        </webdiyer:AspNetPager>
		</form>
</BODY>
</HTML>

该示例所用的Sql Server存储过程代码如下（仅适用于SQL Server 2005）：

CREATE PROCEDURE P_GetPagedOrders2005
	@startIndex INT, 
    @pageSize INT 
AS
begin
WITH orderList AS ( 
SELECT ROW_NUMBER() OVER (ORDER BY O.orderid DESC)AS Row, O.orderid,O.orderdate,O.customerid,C.CompanyName,E.FirstName+' '+E.LastName as EmployeeName 
from orders O
left outer join Customers C
on O.CustomerID=C.CustomerID
left outer join Employees E
on O.EmployeeID=E.EmployeeID)

SELECT orderid,orderdate,customerid,companyName,employeeName
FROM orderlist
WHERE Row between @startIndex and @startIndex+@pageSize-1
end
