推荐答案

<asp:updatepanel runat="server" xmlns:asp="#unknown">
                          <contenttemplate>
                              <asp:timer id="Timer1" runat="server" interval="1000" ontick="Timer1_Tick"></asp:timer>

                              <asp:repeater runat="server" id="rptOffers" onitemdatabound="rptOffers_ItemDataBound">
                                  <itemtemplate>
                                              <asp:label id="Label3" runat="server" text="<%#Eval("DueDate") %>" visible="False">
                                              </asp:label>
                                              <asp:label id="Label1" runat="server"></asp:label>
                                              <asp:label id="Label2" runat="server" />


                                  </itemtemplate>
                              </asp:repeater>
                          </contenttemplate>
                          <triggers>
                              <asp:asyncpostbacktrigger controlid="Timer1" eventname="Tick" />
                          </triggers>
                      </asp:updatepanel>

和CodeBehind你使用这个块

and CodeBehind you use this block

protected void Timer1_Tick(object sender, EventArgs e)
       {

           foreach (RepeaterItem item in rptOffers.Items)
           {
               var label2 = item.FindControl("Label2") as Label;

               var label3 = item.FindControl("Label3") as Label;
               var time2 = DateTime.Parse(label3.Text);
               label2.Text = (time2 - DateTime.Now).Days + " " + (time2 - DateTime.Now).Hours + " " + (time2 - DateTime.Now).Minutes + " " + (time2 - DateTime.Now).Seconds + " ";

           }

       }
