.

                        <br />

                        <asp:Button runat="server" ID="Button1" Text="Submit Successful Async Postback"

                            OnClick="SuccessProcessClick_Handler" OnClientClick="ClearErrorState()" />

                        <asp:Button runat="server" ID="Button2" Text="Submit Async Postback With Error"

                            OnClick="ErrorProcessClick_Handler" OnClientClick="ClearErrorState()" />

                        <br />

                    </asp:Panel>

                </ContentTemplate>

            </asp:UpdatePanel>

            <div id="AlertDiv">

                <div id="AlertMessage">

                </div>

                <br />

                <div id="AlertButtons" >

                    <input id="OKButton" type="button" value="OK" 

                           runat="server" onclick="ClearErrorState()" />

                </div>

           </div>

    </form>

</body>

</html>

运行后时界面：

发生异常信息：

 

五．Services属性

Services用来管理对WebService的调用，通过<asp:ServiceReference>标签可以在Services中注册一个WebService，在运行时ScriptManager将为每一个ServiceReference对象生成一个客户端代理，<asp:ServiceReference>标签一个很重要的属性是Path，用来指定WebService的路径，如下所示：

<asp:ScriptManager ID="SM1" runat="server">

    <Services>

        <asp:ServiceReference Path="Service.asmx"/>

    </Services>

</asp:ScriptManager>
