Hi,
Since you said your code work locally, I think we will not able to reproduce it.
Can you test this ? after file be uploaded , try add a new button
void
Button2_Click(object sender, EventArgs e)
{
Response.Redirect(Request.Url.ToString(), false);
}
Do not redirect it in Uploader1_UploadCompleted event.
Or you can also try another way , select some files, and after the first file be uploaded , press F5 to refresh the page.
Regards,
Terry
