Ajax工具包AjaxFileUpload抛出异常 [英] Ajax Toolkit AjaxFileUpload throw exception

问题描述

我有我想补充我加了一个工具包，脚本经理母版页的文件上传报名表
然后我添加了一个ajaxfileupload控制<$c$c><http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/AjaxFileUpload/AjaxFileUpload.aspx>

在ASPX看起来像这样

 ＆LT; ajaxToolkit：AjaxFileUpload ID =AjaxFileUpload1ThrobberID =myThrobberContextKeys =弗雷德
                AllowedFileTypes =JPG，JPEGMaximumNumberOfFiles =2=服务器UploadedComplete =AjaxFileUpload1_UploadedComplete/＆GT;
 

方法AjaxFileUpload1_UploadedComplete是空的现在。

我得到这个例外，没有事件被触发，除了在Page_Load

  

Sys.ArgumentException：Sys.ArgumentException：无法反序列化。该
  数据不对应于有效的JSON

解决方案

我意识到这是一个老问题，但我认为这是由控制错误造成的。追加查询字符串参数，但假定没有现有的参数。

有细节，这里修复： HTTPS：//ajaxcontroltoolkit.$c$cplex。 COM /工作项目/ 27149 （涉及更改源和重建工具包）

I have an entry form which I want to add a file uploader I added a toolkit script manager to the master page then i added an ajaxfileupload control <http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/AjaxFileUpload/AjaxFileUpload.aspx>

the aspx looks like this

<ajaxToolkit:AjaxFileUpload ID="AjaxFileUpload1" ThrobberID="myThrobber" ContextKeys="fred"
                AllowedFileTypes="jpg,jpeg" MaximumNumberOfFiles="2" runat="server" UploadedComplete="AjaxFileUpload1_UploadedComplete" />

the method AjaxFileUpload1_UploadedComplete is empty for now.

I got this exception and no event is firing except for the page_load

Sys.ArgumentException: Sys.ArgumentException: Cannot deserialize. The data does not correspond to valid JSON.

解决方案

I realise this is an old question but i think this is caused by a 'bug' in the control. It appends query string parameters but assumes there are no existing parameters.

There are details and a fix here: https://ajaxcontroltoolkit.codeplex.com/workitem/27149 (involves changing the source and rebuilding the toolkit)
