后台代码：

{
GridView theGrid = sender as GridView;
int newPageIndex = 0;
if (e.NewPageIndex == -3)
{
//点击了Go按钮
TextBox txtNewPageIndex = null;
//GridView较DataGrid提供了更多的API，获取分页块可以使用BottomPagerRow 或者TopPagerRow，当然还增加了HeaderRow和FooterRow
GridViewRow pagerRow = theGrid.BottomPagerRow;
if (pagerRow != null)
{
//得到text控件
txtNewPageIndex = pagerRow.FindControl("txtNewPageIndex") as TextBox;
}
if (txtNewPageIndex != null)
{
//得到索引
newPageIndex = int.Parse(txtNewPageIndex.Text) - 1;
}
}
else
{
//点击了其他的按钮
newPageIndex = e.NewPageIndex;
}
//防止新索引溢出
newPageIndex = newPageIndex < 0 ? 0 : newPageIndex;
newPageIndex = newPageIndex >= theGrid.PageCount ? theGrid.PageCount - 1 : newPageIndex;
//得到新的值
theGrid.PageIndex = newPageIndex;
//重新绑定
GridView1.DataBind();
