//绑定子类
    protected void dl_ItemDataBound(object sender, DataListItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
        {
            //绑定子类
            CheckBoxList chk = (CheckBoxList)e.Item.FindControl("chklSub");
            Label lblCountryID = (Label)e.Item.FindControl("lblCountryID");
            string sql = @"select * from T_directory where Parentid = '" + lblCountryID.Text + "' order by DirNameChs";
            DataSet ds = DbHelperSQL.Query(sql);
            chk.DataTextField = "DirNameChs";
            chk.DataValueField = "directoryID";
            chk.DataSource = ds;
            chk.DataBind();
            //确定钩选
            CustomSearchBLL Search = new CustomSearchBLL();
            ds = Search.GetList("UserName='" + UserName + "' and CountryID='" + lblCountryID.Text + "'");
            if (ds.Tables[0].Rows.Count > 0)
            {
                ((CheckBox)e.Item.FindControl("chklCountry")).Checked = true;
                for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
                {
                    foreach (ListItem Check in chk.Items)
                    {
                        if (Check.Value == ds.Tables[0].Rows[i]["SubID"].ToString())
                        {
                            Check.Selected = true;
                        }
                    }
                }
            }
        }
    }
