有个关于分页的问题

按照你的简单意思 datalist 估计更好

default.aspx.cs:
public partial class _Default : System.Web.UI.Page
{
string connectString = "";//定义自已的连接串
protected void Page_Load(object sender, EventArgs e)
{
AjaxPro.Utility.RegisterTypeForAjax(typeof(_Default));
}
[AjaxPro.AjaxMethod]
public DataTable GetDataTable()
{
SqlDataAdapter ad = new SqlDataAdapter("select * from tableName", connectString);
DataSet ds = new DataSet();
ad.Fill(ds);
int num = ds.Tables[0].Rows.Count;
return ds.Tables[0];
}
}default.aspx:

datalist没有自动分页吧，是不是得自定义？

本来不想回这贴的
这段代码我贴N边了
建议lZ先在CSDN搜索一下
再发帖//ASP.NET2.0中datalist仿百度分页
