好.问题是?

您说您已经动态创建了一个文件上传控件.现在，您有了一个文件上传控件.

在提交页面之前，在Javascript中单击按钮，获取文件控件及其详细信息.
样本:

Ok. And the issue is?

You say you already have created a fileupload control dynamically. Now, you have a fileupload control.

Before submitting the page, on button click, in Javascript, get the filecontrol and it''s details.
Sample:

var myFControl = document.getElementById("<%= myFileUpload1.ClientID %>");
alert("Filename selected: " + myFControl.value);

请参阅文件上传控件的HTML Dom对象: http://www.w3schools.com/jsref/dom_obj_fileupload.asp [ ^ ]
