推荐答案

正常的FileUpload控件不适用于Update Panel-已知的事情-它需要完整的回发.

有一个新的AjaxControlToolkit的Ansyc上传控件: AsyncFileUpload演示 [ ^ ]

或

使用jQuery，查看此示例并尝试:
教程:多种文件上传魔术 [ ^ ]
Ajax文件上传 [使用jQuery的AJAX多文件上传表单 [

Normal FileUpload control would not work with Update Panel - known thing - it needs full postback.

There is a new AjaxControlToolkit''s Ansyc upload control: AsyncFileUpload Demonstration[^]

OR

Using jQuery, look at this sample and try:
Tutorials:Multiple File Upload Magic[^]
Ajax File Upload[^]
AJAX Multiple File Upload Form Using jQuery[^]

Try out.

您必须添加PostBackTrigger 使其起作用
