An exception of type 'System.FormatException' occurred in mscorlib.dll but was not handled in user code

} 
}

在Page_Load中以下行出现的错误事件：

getPostData(Convert.ToInt32(postident));

变量会从

Page.Route.Values["postid"].ToString()

其初始值，我不知道为什么这个变量的值发生了变化，但它已经改变为值：

the value of the string at this time is: 

"AjaxFileUploadHandler.axd"

，但我不知道为什么已经改变为此。我认为这是导致错误的变化。事件HtmlEditorExtender1_ImageUploadComplete未被解雇，我不确定原因。任何可以提供的建议或见解都会受到感谢。有什么我失踪？我有另一个htmleditorextender在另一个页面上正常工作。这是一个formview，所以我不知道这是否有任何区别。

您使用的是什么版本的Ajax Control Toolkit？ –

@MikhailTymchuk我正在使用版本15.1.4.0 –

你有没有在网页上的任何JavaScript？浏览器控制台有任何错误？ –

看起来你有路由规则将你期望的变量映射到“AjaxFileUploadHandler.axd”。

添加一个新的路线，将触发图片上传，所以更多一般postid路线不会被击中。
