datalist分页是通过PagedDataSource类来实现的。该类封装数据绑定控件与分页相关的属性，以允许该控件执行分页操作。
后台代码
using System.data.sqlclient;
DB db = new DB();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
bind();
}
}
public void bind()
{
int currentpage = Convert.ToInt32(labnowpage.Text);
PagedDataSource ps = new PagedDataSource();//生成pageddatasource的实例
string selstr = "select * from tb_CounterInfo";
string slqcon = ConfigurationManager.AppSettings["getcon"].ToString();
SqlConnection con = new SqlConnection(slqcon);
con.Open();
SqlDataAdapter da = new SqlDataAdapter(selstr,con);
DataSet ds=new DataSet();
da.Fill(ds, "CounterInfo");
ps.DataSource = ds.Tables["CounterInfo"].DefaultView;
ps.AllowPaging = true;
ps.PageSize = 4;
ps.CurrentPageIndex = currentpage - 1;
lkbtnfirst.Enabled = true;
lkbtnfront.Enabled = true;
lkbtnnext.Enabled = true;
lkbtnlast.Enabled = true;
if (currentpage == 1)
{
lkbtnlast.Enabled = false;
lkbtnfront.Enabled = false;
}
if (currentpage == ps.PageCount)
{
lkbtnnext.Enabled = false;
lkbtnlast.Enabled = false;
}
this.labcount.Text = Convert.ToString(ps.PageCount);
this.DataList1.DataSource = ps;
this.DataList1.DataKeyField = "ID";
this.DataList1.DataBind();
}
protected void lkbtnfirst_Click(object sender, EventArgs e)
{
this.labnowpage.Text = "1";
bind();
}
protected void lkbtnfront_Click(object sender, EventArgs e)
{
this.labnowpage.Text = Convert.ToString(Convert.ToInt32(this.labnowpage.Text) - 1);
bind();
}
protected void lkbtnnext_Click(object sender, EventArgs e)
{
this.labnowpage.Text = Convert.ToString(Convert.ToInt32(this.labnowpage.Text) + 1);
bind();
}
protected void lkbtnlast_Click(object sender, EventArgs e)
{
this.labnowpage.Text = this.labcount.Text;
bind();
}
获取DataList控件中控件数据的方法通常使用两种方法：
一种是通过e.Item.Controls[0]索引直接访问Item中的控件，另一种方法是使用FindControl()方法来查找。
