Hi craymers,
You can set the Upload type to “IFrame” for the IE 9 browser, it will work with keyboard. But the iframe mode only support o set 1 file at one time. It does not support multiple files select function.
protected override void OnLoad(EventArgs e)
{
if(is IE9)
{
uploader1.UploadType="IFrame";
}
base.OnLoad(e);
}
Regards,
Ken
