问题描述

我已将AutoCompleteExtender绑定到文本框，以向用户显示建议

。如果我利用网络服务获取

结果，一切正常。但是，我想将Web服务代码放入页面方法中。我运行调试器只是为了发现从未输入[WebMethod]。

以下是我已经尝试过的一些没有成功的事情。看来

这是一个常见的问题。


-将[WebMethod]属性添加到代码隐藏方法的顶部。

-Added / removed" Static"作为公共方法定义的一部分。

- 删除了ServicePath来自AutoCompleteExtender .aspx页面的属性。


我的文本框和扩展程序控件嵌入到用户控件（.ascx）中，

放在ContentPanel中继承来自MasterPage。我不确定这可能是问题的一部分。当我查看浏览器源代码时，

javascript呈现ServicePath。默认情况下我的aspx

页面，但我的[WebMethod]位于pagename.ascx.cs。另外，我试过了

，其中包括ServicePath = pagename.ascx.cs。但仍然没有运气。


此时，我不知道还有什么可以尝试的。我想要移动到页面方法的主要原因是因为我需要访问Web服务可用的控件，而不是
。此外，我不认为我的需求在这里构成

需要网络服务。


任何帮助都将不胜感激！


谢谢，


Trent

我在[WebService]之后立即应用[ScriptMethod]并且没有修复

它。还有其他想法吗？谢谢！

你好，


我有一个使用这个模式的工作自动完成扩展器：


在Codebehind：


[WebMethod]

[ScriptMethod]

公共静态字符串MyMethod（字符串contextKey）

{在


< ajaxToolkit：AutoCompleteExtender runat =" server"

ID = " tbAutoCompleteExtender" TargetControlID =" tbTextBox"

ServiceMethod =" MyMethod"

MinimumPrefixLength =" 2" CompletionInterval =" 1000"
EnableCaching =" true"

CompletionSetCount =" 12" />


请注意，代码隐藏方法必须在.aspx文件中，即使

自动完成扩展程序位于用户控件中。


您是否安装了最新版本的Ajax工具包？它来自

2月...所以只有几天的时间。


祝你好运，

Henning Krause

I have tied an AutoCompleteExtender to a textbox to indicate suggestions to
the user. Everything works fine if I utilize a webservice to fetch the
results. However, I want to put the web service code into a page method. I
have run the debugger only to find that the [WebMethod] is never entered.
Here are some of the things I have already tried with no success. It appears
that this is a common problem.

-Added the [WebMethod] attribute to the top of the code-behind method.
-Added/removed "Static" as part of the public method definition.
-Removed the "ServicePath" attribute from the AutoCompleteExtender .aspx page.

My textbox and extender control are embedded into a user control(.ascx) that
is placed within a ContentPanel inherited from a MasterPage. I''m not sure if
this could be part of the problem. As I view the browser source code, the
javascript renders the "ServicePath" to be looking by default at my aspx
page, but my [WebMethod] lives in pagename.ascx.cs. Also, I have tried
including "ServicePath=pagename.ascx.cs" and still no luck.

At this point, I don''t know what else to try. The main reason I''m wanting
to move to a page method is because I need access to controls which aren''t
available to the web service. Also, I don''t think my needs here constitute
the need for a web service.

Any help would be greatly appreciated!

Thanks,

Trent

Hello,

you''ll have to specify the [ScriptMethod] attribute in addition to the
[WebService] attribute.

I applied [ScriptMethod] immediately after [WebService] and that didn''t fix
it. Any other thoughts? Thanks!

Hello,

I''ve a working autocomplete extender using this schema:

In Codebehind:

[WebMethod]
[ScriptMethod]
public static string MyMethod(string contextKey)
{}

In aspx site:

<ajaxToolkit:AutoCompleteExtender runat="server"
ID="tbAutoCompleteExtender" TargetControlID="tbTextBox"
ServiceMethod="MyMethod"
MinimumPrefixLength="2" CompletionInterval="1000"
EnableCaching="true"
CompletionSetCount="12" />

Note that code-behind method must be in the .aspx file, even if the
autocomplete extender is in a usercontrol.

Do you have the latest version of the Ajax toolkit installed? It''s from
february... so only a few days old.

Best regards,
Henning Krause
