Wap页面使用asp.net中移动控件List分页

简介:一、创建一个类 public class Navigation { private string _siteName, _siteURL; public Navigation(string siteName, String siteURL) { _siteName = siteName; _siteURL = siteURL; } public string SiteName...

一、创建一个类

public class Navigation

{

private string _siteName, _siteURL;

public Navigation(string siteName, String siteURL)

{

_siteName = siteName;

_siteURL = siteURL;

}

public string SiteName { get { return _siteName; } }

public string SiteURL { get { return _siteURL; } }

}

二、分页

dbAccess mydb = new dbAccess();

mydb.SqlStr = "select count(bookid) as totalid from szhotline where bkcity='" + bkcity + "' and atype=" + atype;

DataSet dsTotal = mydb.readTable("szhotline");

int countTotal = Convert.ToInt32(dsTotal.Tables["szhotline"].Rows[0]["totalid"].ToString()); //总记录数

int totalPage = 0; //总页数

if (countTotal % perPage == 0)

totalPage = Convert.ToInt16(countTotal/perPage);

else

totalPage = Convert.ToInt16(countTotal/perPage) + 1;

int cp_n, cp_p;

if (cur_page > 1)

cp_p = cur_page - 1;

else

cp_p = 1;

if (cur_page < totalPage)

cp_n = cur_page + 1;

else

cp_n = totalPage;

link_p.NavigateUrl = "szhotline.aspx?page_c=" + cp_p + "&bkcity=" + bkcity + "&atype=" + atype;

link_n.NavigateUrl = "szhotline.aspx?page_c=" + cp_n + "&bkcity=" + bkcity + "&atype=" + atype;

List1.DataTextField="SiteName";

List1.DataValueField="SiteURL";

ArrayList arr = new ArrayList();

mydb.SqlStr = "SELECT top " + perPage + " * from (select top " + perPage*Convert.ToInt16(cur_page) + " bookid,bookname from szhotline where atype=" + atype + " and bkcity='" + bkcity + "' order by bookid desc) order by bookid asc";

DataSet myds = mydb.readTable("szhotline");

for (int i=0; i {

string bkname = myds.Tables["szhotline"].Rows["bookname"].ToString().Trim();

string bkurl = "szhotdet.aspx?bookid=" + myds.Tables["szhotline"].Rows["bookid"].ToString().Trim();

arr.Add(new Navigation(bkname, bkurl));

}

List1.DataSource = arr;

List1.ItemsAsLinks = true;

List1.DataBind ();

ActiveForm = list;

说明:其中dbAccess是自定义的操作数据库的类,由于数据库使用的是Access。采用的分页采用了select top n * from (select * m from table order by id desc) order by id desc的方式,调整m,n两个参数分页。
