Hi,

I want to Set asp:fileupload Filename at runtime. When I try to do, it
shows "Readonly" error. Anyway to achieve this.

You can't for security reasons.

Absolutely not, for fairly obvious security reasons!

Imagine a public website with a hidden FileUpload control which uploaded
people's accounts database, or their Windows password file...

It is a read-only property and is automatically set by the ASP.NET runtime
when the user posts back the page with uploaded file from the browser.

Actually My requirement was-
I have a File Upload control and one DropDownControl. I set
AutoPostBack is true to my DDL. After choosing Filecontrol, if i
change DDL value. The filename has got reset. which our users don't
like this. Do u have any alternate?

 

[Mark Rae]

The filename has got reset.

That's right - the filename won't survive the postback...

Do u have any alternate?

No.

No.

A FileUpload will not retain its' value between postbacks for security
reasons. Therefore, as long as the ListBox doesn't post back, you won't have
a problem.
