I am am in need of help with regards to the following error that I am getting when clicking on "Add AutoComplete page method" on a textbox control in an aspx page: "Cannot create page method "GetCompletionList" because no CodeBehind or CodeFile file was found!". This is related to adding an Ajax control to a webpage object such as a textbox.
我需要有关在 aspx 页面中的文本框控件上单击“添加自动完成页面方法”时出现的以下错误的帮助：“无法创建页面方法“GetCompletionList”，因为没有 CodeBehind 或 CodeFile 文件成立！”。这与将 Ajax 控件添加到网页对象（例如文本框）有关。
I have successfully added the Ajax Control Toolkit to my website toolbox in Visual Studio 2012. I have followed the following tutorial http://www.asp.net/ajaxlibrary/act_AutoC… and get the error when I get to step 4.
我已经成功地将 Ajax Control Toolkit 添加到我在 Visual Studio 2012 中的网站工具箱中。我遵循了以下教程http://www.asp.net/ajaxlibrary/act_AutoC... 并在我到达第 4 步时收到错误消息。

Manually write the code-behind and then apply the method name GetCompletionListto the ServiceMethodattribute of the extender control, like this:
手动编写代码隐藏，然后将方法名称GetCompletionList应用于ServiceMethod扩展器控件的属性，如下所示：
<asp:AutoCompleteExtender ServiceMethod="GetCompletionList" ID="txtManufacturer_AutoCompleteExtender" runat="server" DelimiterCharacters="" Enabled="True" ServicePath="" TargetControlID="txtManufacturer" UseContextKey="True">
</asp:AutoCompleteExtender>
