标题: f:Grid OnPageIndexChange监听方法
这是表格的设置信息
<f:Grid ID="Grid2" Title="表格" EnableCollapse="true" PageSize="5" ShowBorder="true"  ShowHeader="true" IsDatabasePaging="true" AllowPaging="true" ShowPagingMessage="true"
                              runat="server" EnableCheckBoxSelect="false" Width="1000px" Height="300" DataKeyNames="ID,city,county,street,village,reporter,reportUnit,operType,operTime,checked,remark"
                              EnableRowDoubleClickEvent="true"  >

在OnPageIndexChange对应的AddressReportGrid_PageIndexChange方法里面的Grid2.pageIndex 一直为0，我是按照在线的代码的思路设计的。
主要的方法几乎没改动
public void AddressReportGrid_PageIndexChange(object sender, EventArgs e)
      {
         Alert.Show(Grid2.PageIndex.ToString());
         AddressReportGridBind();
      }
      public void AddressReportGridBind()
      {
         Grid2.RecordCount = reportTable.Rows.Count;
         DataTable table = GetReportGridPagedDataTable(Grid2.PageIndex, Grid2.PageSize);

         //绑定到Grid
         Grid2.DataSource = table;
         Grid2.DataBind();
      }
      public DataTable GetReportGridPagedDataTable(int pageIndex, int pageSize)
      {
         DataTable source = reportTable;

         DataTable paged = source.Clone();

         int rowbegin = pageIndex * pageSize;
         int rowend = (pageIndex + 1) * pageSize;
         if (rowend > source.Rows.Count)
         {
            rowend = source.Rows.Count;
         }

         for (int i = rowbegin; i < rowend; i++)
         {
            paged.ImportRow(source.Rows[i]);
         }

         return paged;
      }

自己结贴，pageIndex属性不能随着控件的改变而改变，源码中有//Grid1.PageIndex = e.NewPageIndex;
的注释，我们要把事件得到的新pageindex赋值给Gird的pageIndex，这样分页就能正常实现了
