后台代码：

复制代码 代码如下:

protected void myPage_PageChanged(object sender, EventArgs e)
         {
             GridViewRow pagerRow = viewIShow.BottomPagerRow;
             AspNetPager myPage = (AspNetPager)pagerRow.Cells[0].FindControl("myPage");
             viewIShow.PageIndex = myPage.CurrentPageIndex - 1;
         }

         protected void viewIShow_DataBound(object sender, EventArgs e)
         {
             GridViewRow pagerRow = viewIShow.BottomPagerRow;
             AspNetPager myPage = (AspNetPager)pagerRow.Cells[0].FindControl("myPage");

             GridView view = (GridView)sender;
             myPage.PageSize = view.PageSize;
             myPage.CurrentPageIndex = view.PageIndex +1; //GridView分页索引是从0开始，AspNetPager是从1开始的
         }

         protected void ObjectDataSource1_Selected(object sender, ObjectDataSourceStatusEventArgs e)
         {
             DataSet ds = (DataSet)e.ReturnValue; //ObjectDataSource查询方法返回什么类型就转成什么类型

             GridViewRow pagerRow = viewIShow.BottomPagerRow;
             AspNetPager myPage = (AspNetPager)pagerRow.Cells[0].FindControl("myPage");

             if (ds == null)
             {
                 myPage.RecordCount = 0;
             }
             else
             {
                 myPage.RecordCount = ds.Tables[0].Rows.Count;
             }
         }
