如何在具有多个表的嵌套转发器中显示数据？

Question

我正在尝试创建一个Employee Shift Scheduler。 目前，我正试图显示当前的变化。

以下是我目前的输出：

如您所见，星期六有两班倒。我想在一个标题下显示这两个转变 - “2017年6月3日星期六”，而不是重复。

有人可以告诉我为了达到这个目的，我需要对代码做出哪些更改？

我在下面发布了我当前的代码：

让我们从那个错误开始吧。更改以下内容时是否会出现相同的日期错误？如果没有，发生了什么？

protected void repFullSchedule_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    using (SqlConnection con = new SqlConnection(connectionString))
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Repeater repCurrentShift = (Repeater)(e.Item.FindControl("repCurrentShifts"));


            string Start_time = DataBinder.Eval(e.Item.DataItem, "Start_Time").ToString();
            //DateTime my_Time = DateTime.ParseExact(Start_time, "dd/MM/yyyy HH:mm", System.Globalization.CultureInfo.InvariantCulture);
            SqlCommand cmd = new SqlCommand("Select Job_Type FROM Shift WHERE Start_Time=@my_Time", con);
            cmd.Parameters.AddWithValue("@my_Time", Start_time);
            SqlDataAdapter sda = new SqlDataAdapter(cmd);
            DataTable dt = new DataTable();
            sda.Fill(dt);
            repCurrentShift.DataSource = dt;
            repCurrentShift.DataBind();
        }
    }
}
