其实说实话,这个控件不好用,如果我们要完成分页功能,可以用.net提供的pagedateSource这个分页类来完成! 下面是用这个控件的部分代码,不全,建议还是用pagedateSource来分页,具体怎么实现你百度一下就ok了! 

//页面加载事件
protected void Page_Load(object sender, EventArgs e)
{
Bind();
}
private void Bind()
{
//将总条数放到分页控件中
DataTable dt1 = null;
dt1 = DataCtrl.selecttable("select count(classname) from mess_class","tabnl");
// this.pager.RecordCount=System.Convert.ToInt32(ds.Tables[0].Rows[0][0]); 
this.AspNetPager1.RecordCount = System.Convert.ToInt32(dt1.Rows[0][0]);
Bind1();

}
private void Bind1()
{
SqlConnection conn = new SqlConnection("server=.;uid=sa;pwd=xuedao;database=zhaoxuedaonet");
SqlCommand comm = new SqlCommand("select classname from mess_class",conn);
conn.Open();
comm.ExecuteNonQuery();

DataSet ds = new DataSet();
SqlDataAdapter dapter = new SqlDataAdapter(comm);
dapter.Fill(ds, AspNetPager1.PageSize * (AspNetPager1.CurrentPageIndex-1),AspNetPager1.PageSize,"table");
this.DataList1.DataSource = ds.Tables["table"].DefaultView;
this.DataList1.DataBind();
//AspNetPager1.CustomInfoText = "记录总数：" + AspNetPager1.RecordCount.ToString() + "";
//AspNetPager1.CustomInfoText = "总页数：" + AspNetPager1.PageCount.ToString() + "";
//AspNetPager1.CustomInfoText = " 当前页：" + AspNetPager1.CurrentPageIndex.ToString() + ""; 

//myda.Fill(ds, pager.PageSize * (pager.CurrentPageIndex - 1), pager.PageSize, "article");
//this.dgList.DataSource = ds.Tables["article"];
//this.dgList.DataBind();
////动态设置用户自定义文本内容 
//pager.CustomInfoText = "记录总数：" + pager.RecordCount.ToString() + "";
//pager.CustomInfoText += " 总页数：" + pager.PageCount.ToString() + "";
//pager.CustomInfoText += " 当前页：" + pager.CurrentPageIndex.ToString() + ""; 


}
//分页事件
protected void AspNetPager1_PageChanged(object src, Wuqi.Webdiyer.PageChangedEventArgs e)
{
AspNetPager1.CurrentPageIndex = e.NewPageIndex;
Bind1();
}
