             <Triggers>

                 <asp:AsyncPostBackTrigger ControlID="btnShua" EventName="Click" />

             </Triggers>

         </asp:UpdatePanel>

     <div>

         <asp:Button ID="btnShua" runat="server" Height="21px" OnClick="btnShua_Click" Text="选择日期（刷新）" Width="162px" />

         <asp:Button ID="btnWu" runat="server" OnClick="btnShua_Click" Text="选择日期（无刷新）" />

     </div>

     </form>

 </body>

 </html>

因为第一个按钮是无刷新的应该也在updatePanel中显示，所以更改如下属性，单击updatepanel

 using System.Web.UI;

 using System.Web.UI.WebControls;

 using System.Text;

 public partial class _Default : System.Web.UI.Page

 {

     protected void Page_Load(object sender, EventArgs e)

     {

     }

     protected void btnShua_Click(object sender, EventArgs e)

     {

         string[] week = new string[] { "星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六" };

         StringBuilder sbDate = new StringBuilder();

         sbDate.Append("请选择日期是：");

         sbDate.Append(Calendar1.SelectedDate.Year + "年");

         sbDate.Append(Calendar1.SelectedDate.Month + "月");

         sbDate.Append(Calendar1.SelectedDate.Day + "日");

         sbDate.Append(week[(int)Calendar1.SelectedDate.DayOfWeek]);

         Label1.Text = sbDate.ToString();

     }

 }

然后两个按钮的单击事件都改成 btnShua_click
