用户控件中的AJAX控件 [英] AJAX Control in a User control

问题描述

我开发了一个用户控件，其中包含一个Ajax Toolkit异步文件上载控件.
将用户控件放到页面中并运行该页面时，浏览器将引发异常:

I have developed a user control which has an Ajax Toolkit Async File Upload control in it.
When the user control is dropped into a page and the page is run the browser throws an exception:

Microsoft JScript运行时错误:Sys.ArgumentUndefinedException:值不能不确定.
参数名称:baseType

Microsoft JScript runtime error: Sys.ArgumentUndefinedException: Value cannot be undefined.
Parameter name: baseType

在javascript函数中:AjaxControlToolkit.AsyncFileUpload.registerClass

我一直在寻找某种解决此问题的方法，但无济于事.问题在于将Ajax控件放入用户控件中，因为我已经测试了该理论，并且可以用Ajax控件工具包中的几乎所有控件重现它.

如果有人遇到过这个问题，并且可以指出解决方案，我将不胜感激.

问候

Tom

In the javascript function: AjaxControlToolkit.AsyncFileUpload.registerClass

I have searched for some kind of solution to this issue to no avail. the issue is to do with placing the Ajax Control in the User Control as I have tested this theory and its reproducable with pretty much all the controls in the Ajax Control Toolkit.

If anyone has come across this and could point me towards a solution I would be grateful.

Regards

Tom

然后，您的搜索还不够好， ^ ]

You haven''t search very well then, http://www.google.com/search?rlz=1C1CHFX_enUS373US373&sourceid=chrome&ie=UTF-8&q=Microsoft+JScript+runtime+error:+Sys.ArgumentUndefinedException[^]

您好，请检查ajax控件的加载过程...
似乎控件是在脚本管理器加载脚本之前加载的....可能不是确切的答案...请检查一次

Hi can u please check the loading process of the ajax controls...
it seems the controls are loading before the script manager loads the script....it may not be exact answer...please check once
