asp:FileUpload - possible to change file filter?

[Handy Andy]

Anyone know how to change the list of file types displayed by the
asp:FileUpload control in its file selection dialog, or am I stuck with 'All
Files(*.*) Pictures (*.gif, *.jpg) HTML (*.htm, *.html)'?

TIA

The best way is probably to use JavaScript. The input type="file" does have
an accept attribute, but I'm nto sure how well supported it is.

JavaScript solution:

Everything I found on Accept was pretty old though, so IE 6.0 and Firefox
might play nicer with it.

while there is an accept attribute on the file input, no browser i know
supports its. you're stuck.

That's a real nuisance.

Thanks for the replies.

Try this

Try
<asp:RegularExpressionValidator
id="FileUpLoadValidator" runat="server"
ErrorMessage="Somente fotos JPG e GIF."
ValidationExpression="^(([a-zA-Z]|(\\{2}\w+)\$?)(\\(\w[\w].*))(.jpg|.JPG|.gif|.GIF)$"
ControlToValidate="FileUpload1"></asp:RegularExpressionValidator>
