initiating a file download via a Button

[matt]

hello,

how does one inititate the dowloading of a file via a button click? for
example, i have a file sitting on the webserver; when the user clicks
on a button, i'd like them to see their web browser's "save this file
to the file system" dialogue and have them download it.

im not even sure if this would be server-side or client-side. either
works for me.

any tips?

thanks!
matt

Just redirect the user to that file like you would
any other url.

....that didnt work for me for some reason.

no sweat tho, i found another way:

//send file to user
Response.Clear();
Response.ContentType = "application/octet-stream";
Response.AppendHeader("content-disposition", "attachment; filename=" +
fileName);
Response.Flush();
Response.WriteFile(fileAbPath);
Response.End();

....this has an added advantage of allowing me to use a dynamically
generated filename. cool.


thanks,
matt
