增加anp控件方法: vs20008/vs2010 左侧->工具箱->常规->选项->浏览->选择AspNetPage.dll 把控件拉入前台页面如：default.aspx 想要显示AspNetPage处。

以上是非常原始的样式，非常难看，所以，如果要达到良好的用户体验，还得加上以下的样式代码。
/*拍拍风格*/ .paginator { font: 12px Arial,Helvetica,sans-serif;padding:10px 20px 10px 0; margin: 0px;} .paginator a {padding: 5px 10px; border: solid 1px #ddd; background: #fff; text-decoration: none;margin-right:2px} .paginator a:visited {padding: 5px 10px; border: solid 1px #ddd; background: #fff; text-decoration: none;} .paginator .cpb {padding: 5px 10px;font-weight: bold; font-size: 13px;border:none;} .paginator a:hover {color: #fff; background: #ffa501;border-color:#ffa501;text-decoration: none;padding:5px 10px;} /*淘宝风格*/.paginator { font: 12px Arial,sans-serif;padding:10px 20px 10px 0; margin: 0px;} .paginator a {border:solid 1px #ccc;color:#0063dc;cursor:pointer;text-decoration:none;} .paginator a:visited {padding: 1px 6px; border: solid 1px #ddd; background: #fff; text-decoration: none;} .paginator .cpb {border:1px solid #F50;font-weight:700;color:#F50;background-color:#ffeee5;} .paginator a:hover {border:solid 1px #F50;color:#f60;text-decoration:none;} .paginator a,.paginator a:visited,.paginator .cpb,.paginator a:hover {float:left;height:16px;line-height:16px;min-width:10px;_width:10px;margin-right:5px;text-align:center; white-space:Nowrap;font-size:12px;font-family:Arial,Simsun;padding:0 3px;}
实际上，当数据多的时候，样式还是不能很好的控制。只好用jquery控制：$(".paginator").css("width","100%");
通常，当分页数量多的时候，最好设置一个调转的文本框和按钮，这个可以在控件的属性里设置。比如超过5页的时候显示跳转文本框。可是用以上代码，当显示跳转文本框的时候，样式不好看。所以，在上面添加上。
在分页控件应用这个paginator样式就可以了。UrlPaging="True"，用url传值会好一点，个人觉得，因为就算不用它也会autopostBlack，一样会跳动。另外，要使得这个控件实现无刷新的效果，就必须将他放置在updatePannel里面。暂时没能找到更好的方法。但是发现很多都是没有实现无刷新的，那就先这样吧。
.paginator input[type="text"]
{
position: absolute;
left: 600px;
top: 4px;
border:solid 1px #ddd;
height:23px;
width:230px;
padding-left:5px;
padding-right:5px;
}
.paginator input[type="submit"]
{
position: absolute;
left: 650px;
top: 4px;
border:1px solid #ddd;
height:27px;
padding-left:10px;
padding-right:10px;
background-color:White;
}
.paginator input[type="submit"]:hover
{
cursor: pointer;
}
sql分页:
string selectsql = "declare @row int;select @row=count(*) from Hotel_Detail where " + where + ";SELECT TOP " + pageSize + " @row as Record,* FROM Hotel_Detail WHERE " + where + " and hotelId NOT IN(SELECT TOP (" + pageSize + "*(" + indexPage + "-1)) hotelId FROM Hotel_Detail where " + where + " ORDER BY UpdateDate desc)ORDER BY UpdateDate desc";
补充：
在实践过程中，发现有一个页面，当自己点击第二页的时候，虽然地址栏上面是第二页的值，但是页面数据没有发生改变。通过调试，发现CurrentPageIndex仍为第一页，
后来用expertMore_PageChanging事件的e.NewPageIndex才解决。
/// <summary>
/// 分页
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void expertMore_PageChanging(object src,Wuqi.Webdiyer.PageChangingEventArgs e)
{
this.expertMore.CurrentPageIndex = e.NewPageIndex;
DataBind();
}
实现Ajax的关键是，设置AspNetPager的UrlPaging=false。天呐！搞了好久，也没个人告诉我一下，浪费了一天几个小时的时间。

若要实现静态化URL分页，注意网页的路径要绝对路径。
