[WebForm]DataList里面如果再有一个DataList,两个数据源都是通过DAL层传出来的,现在不知道子DataList的DataBind()方法如何调用。
C# code

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using BLL;

namespace TestWeb
{
    public partial class _Default : System.Web.UI.Page
    {
        private BLL.Bll bll = new Bll();

        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                DataBindQuestionDataList();
            }
        }

        /// <summary>
        /// 绑定问题list控件
        /// </summary>
        private void DataBindQuestionDataList()
        {
            this.DataList1.DataSource = bll.SearchQuestion();
            this.DataList1.DataBind();
        }

        public DataSet BindReply(Guid id)
        {
            return bll.SearchReply(id);
        }

        protected void dlReply_Load(object sender, EventArgs e)
        {
            
        }
    }
}
