您必须使用fileupload控件的PostFile属性.

You have to use PostedFile property of fileupload control.

http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.fileupload.postedfile%28v=vs.80%29.aspx[^]

One solution is :-
Take a HiddenField Control and save the file path with HiddenField in 1st post back then you can retrieve the file path from HiddenField after many post back also.

Another solution :- You can take the help of ViewState also.

After Use Update Penal....

<triggers><asp:postbacktrigger controlid="ButtonName" xmlns:asp="#unknown">
