ajax实现分页无刷新 (已调试通过)

首先把AjaxPro.dll文件添加到引用中,可以到http://www.schwarz-interactive.de/下载根据你的.net 版本来选择不同的DLL文件.

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];
    }

}
