推荐答案

如果您拥有母版页，那么这将非常有效地完成任务....

您可以在页面中使用计时器控件

If u r having a masterpage then this will be very effective to do the task....

u can have a timer control in page

<asp:Timer ID="Timer1" runat="server" Interval="15000">
                                      </asp:Timer>

然后您可以使用此计时器触发页面的一部分

and later u can trigger a section of a page with this timer

<asp:UpdatePanel ID="UpdatePanel6" runat="server" UpdateMode="Always">
                                                                   <ContentTemplate>

                                                 <b>U can put ur method over here to do the work.................</b>
                                                                   </ContentTemplate>
                                                                   <Triggers>
                                                                       <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
                                                                   </Triggers>
                                                               </asp:UpdatePanel>

使用计时器，您可以每30秒对页面进行一次部分更新. jQuery对于部分更新可能有用.

By using a timer, you can do a partial update of your page say every 30 seconds. jquery might be useful for partial update.
