GridView/ObjectDataSource和AspNetPager整合示例

前台代码：

<asp:GridView ID="viewIShow" runat="server" DataSourceID="ObjectDataSource1"
                    AllowPaging="True" AutoGenerateColumns="False"

后台代码：

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

            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");
