There is no great way that is accepted by all browsers.
Therefore you'll need to double check the file once it's been uploaded and
reject it then.

Use the File Upload control.
You can use a validation control with it to help ensure the file has the
correct extension.
But like I said, you should also double check the PostedFile.ContentType on
the server side to verify it is the kind of file that you think it is.
