前端：.aspx
首先在GridView中启用分页
<asp:GridView ID="gv_ReviewIndex" runat="server" AllowPaging="True" />
设置分页模式，可以在IDE环境中操作
<PagerSettings FirstPageText="首页" LastPageText="末页"
Mode="NextPreviousFirstLast" NextPageText="下一页" PreviousPageText="上一页" />
实现PageIndexChanging事件处理代码：.aspx.cs
protected void gv_ReviewIndex_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gv_ReviewIndex.PageIndex = e.NewPageIndex;
SetBind();
}
