如何在多表中嵌套中继器显示数据？

Question

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

下面是我的电流输出：

正如你所看到的，有上周六2班。我想在一个标题下显示这两个变化 - “2017年6月3日星期六”，而不是重复。

有人可以告诉我为了实现这个目的我需要对代码做些什么改变？

我已张贴下面我当前的代码：

HTML：

<asp:Repeater ID="repSubscription" runat="server" OnItemDataBound="repSubscription_ItemDataBound"> 
        <ItemTemplate> 
         <div class="col-lg-2"> 
          <div class="panel panel-default"> 
           <div class="panel-heading" style="background-color: #3A6EA5; color: white"> 
            <h4 class="panel-title"> 
             <%# Eval("Start_Time", "{0:dddd, dd MMMM yyyy}") %> 
            </h4> 
           </div> 
           <!--panel-heading--> 
           <div class="panel-body"> 
            <asp:Repeater ID="repShift" runat="server"> 
             <ItemTemplate> 
              <b><%# Eval("Job_Title") %></b> 
             </ItemTemplate> 
            </asp:Repeater> 
            </br> 
            <asp:Repeater ID="repEmp" runat="server"> 
             <ItemTemplate> 
              <%# Eval("Employee_Name") %> 
             </ItemTemplate> 
            </asp:Repeater> 
            <br /> 
            <asp:Repeater ID="repTimes" runat="server"> 
             <ItemTemplate> 
              <%# Eval("Start_Time", "{00:HH:MM}") %> - <%# Eval("End_Time" , "{00:HH:MM}") %> 
             </ItemTemplate> 
            </asp:Repeater> 
           </div> 
          </div> 
         </div> 
        </ItemTemplate> 
       </asp:Repeater> 

C＃：

 `private void bindRepeater()

     while (reader1.Read()) 
     { 
       startDate = Convert.ToDateTime(reader1["Start_Date"]); 
       endDate = Convert.ToDateTime(reader1["End_Date"]);' 

       //lblError.Text += startDate.ToString() + "<br/>" + 
    endDate.ToString(); 

     } 
    conn.Close(); 
    using (SqlConnection con = new SqlConnection(connectionString)) 
     {

        repSubscription.DataSource = dt; 
        repSubscription.DataBind(); 
       } 
      } 
    } 
}

让我们先从这个错误。更改下面的内容时是否会得到相同的日期错误？如果不是，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(); 
     } 
    } 
}
