repeater分页之数据源为List实例，求助

w87875251l 2010-11-11 02:14:44

创建了个类Test，里面有个方法，
public IList<Model> GetList()
{
IList<Model> list = new List<Model>();
Model model;
...
SqlDataAdapter ad = new SqlDataAdapter(sql, con);
DataSet ds = new DataSet();
ad.Fill(ds);
.......

return list;}

然后.aspx.cs里面 Page_load( Repeater1.DataSource = test.GetList();
Repeater1.DataBind();)
现在要进行分页，怎么办？

“PagedDataSource类有一个可以赋给任何枚举类型对象的DataSource属性”这句话什么意思

泛型的。。。。。。。。。。。

/// <summary>
/// 根据当前页码，每页条数，取得相应数据。
/// </summary>
/// <param name="pageNum">每页显示条数</param>
/// <param name="currentPage">当前页码</param>
/// <returns></returns>
public static List<Message> getPagesData(int pageNum, int currentPage)
{
List<Message> list = new List<Message>();
StringBuilder sb = new StringBuilder();
sb.Append("select top " + pageNum + " * from zjagzm.message where ");
sb.Append("ID not in (select top " + pageNum * currentPage + " ID from zjagzm.message) order by uptime desc");
DataTable dt = DbHelperSQL.GetDataSet(sb.ToString(), null);
foreach (DataRow row in dt.Rows)
{
Message ms = new Message();
ms.id = Convert.ToInt32(row["id"]);
ms.name = row["name"].ToString();
ms.Title = row["title"].ToString();
ms.uptime = Convert.ToDateTime(row["uptime"]);
ms.contents = row["contents"].ToString();
list.Add(ms);
}
return list;

}

下载AspNetPager

/// <summary>
/// 取得总数
/// </summary>
/// <returns></returns>
public string getTotal()
{
StringBuilder sb = new StringBuilder();
sb.Append("select count(*) total from Test");
DataTable dt = DBHelper.ExecuteDt(sb.ToString());
return dt.Rows[0][0].ToString();
}
/// <summary>
/// 根据当前页码，每页条数，取得相应数据。
/// </summary>
/// <param name="pageNum">每页显示条数</param>
/// <param name="currentPage">当前页码</param>
/// <returns></returns>
public DataTable getPagesData(int pageNum, int currentPage)
{
StringBuilder sb = new StringBuilder();
sb.Append("select top " + pageNum + " * from Test where ");
sb.Append("ID not in (select top " + pageNum * currentPage + " ID from Test)");
return DBHelper.ExecuteDt(sb.ToString());
}

手写分页
GetPageList(int PageIndex,int PageSize)

pds.AllowPaging = true;

pds.PageSize = 15;

Total.Text = pds.Count.ToString();

pds.CurrentPageIndex = Convert.ToInt32(this.labPage.Text) - 1;

Repeater2.DataSource = pds;

LabCountPage.Text = pds.PageCount.ToString();

labPage.Text = (pds.CurrentPageIndex + 1).ToString();

this.lbtnpritPage.Enabled = true;

this.lbtnFirstPage.Enabled = true;

this.lbtnNextPage.Enabled = true;

this.lbtnDownPage.Enabled = true;

if (pds.CurrentPageIndex < 1)
{
this.lbtnpritPage.Enabled = false;

this.lbtnFirstPage.Enabled = false;
}

if (pds.CurrentPageIndex == pds.PageCount - 1)
{
this.lbtnNextPage.Enabled = false;

this.lbtnDownPage.Enabled = false;
}

Repeater2.DataBind();
}

protected void lbtnpritPage_Click(object sender, EventArgs e)
{
this.labPage.Text = Convert.ToString(Convert.ToInt32(labPage.Text) - 1);
this.contrlRepeater();
}
protected void lbtnFirstPage_Click(object sender, EventArgs e)
{
this.labPage.Text = "1";
this.contrlRepeater();
}
protected void lbtnDownPage_Click(object sender, EventArgs e)
{
this.labPage.Text = this.LabCountPage.Text;
this.contrlRepeater();
}

protected void lbtnNextPage_Click(object sender, EventArgs e)
{
this.labPage.Text = Convert.ToString(Convert.ToInt32(labPage.Text) + 1);
this.contrlRepeater();
}
把pds换成你的repeater1
