        <asp:Button ID="Button1"

<%@ Register Assembly="Microsoft.Web.Atlas" Namespace="Microsoft.Web.UI" TagPrefix="cc1" %>
<cc1:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="True">
</cc1:ScriptManager>

<asp:DropDownList ID="aaa" runat="server" AutoPostBack="True" OnSelectedIndexChanged="ddlthumbnail_SelectedIndexChanged">
                        </asp:DropDownList>
                        <cc1:UpdatePanel ID="UpdatePanel1" runat="server">
                            <ContentTemplate>
                                <asp:Label ID="lblatnail" runat="server" Text="" Visible=false></asp:Label>
                                <asp:LinkButton ID="lbtnatnail" runat="server" Visible=false>View</asp:LinkButton><br />
                            </ContentTemplate>
                            <Triggers>
                                <cc1:ControlEventTrigger ControlID="aaa" EventName="SelectedIndexChanged"></cc1:ControlEventTrigger>

                        </cc1:UpdatePanel>

可以在事件中写一些相应的代码!

例如:

DataTable dt = GetID(this.ddlthumbnail.SelectedValue);
string DIL_ImageUploadName = Convert.ToString(dt.Rows[0]["DIL_ImageUploadName"]);

        this.lblatnail.Visible = true;
        lblatnail.Text = Convert.ToString(dt.Rows[0]["DIL_ImageUploadTime"]);
        lbtnatnail.Visible = true;
        this.lbtnatnail.Attributes["href"] = "#";
        this.lbtnatnail.Attributes["onClick"] = "window.open('AEDImageLibarary-PictureView.aspx?PName=" + DIL_ImageUploadName + "','_blank','resizable=yes,scrollbars=yes,status=no,toolbar=no,menubar=no,location=no,left=0,top=0,width=400,height=400')";

<asp:Button ID="Button1"
         Text="Refresh Panel"
          runat="server" />
<asp:ScriptManager ID="ScriptManager1"
          runat="server" />
<asp:UpdatePanel ID="UpdatePanel1"   UpdateMode="Conditional" runat="server">
         <Triggers>
                <asp:AsyncPostBackTrigger ControlID="Button1" />
        </Triggers>
       <ContentTemplate>
              <fieldset>
                  <legend>UpdatePanel 内容</legend>
                  <%=DateTime.Now.ToString() %>
              </fieldset>
       </ContentTemplate>
</asp:UpdatePanel>
