//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();
