Olaf,

 

It seems that , the MagicAjax can't set the new HTML correctly after ajax posting.

 

You can try this before we fix the issue :

 

 

    protected void Uploader1_FileUploaded(object sender, UploaderEventArgs file)
    {
        // Safe uploaded file
        string targetFileName = String.Format("{0}/{1}", Constants.FilePathUpload, file.FileName);
        file.CopyTo(Path.Combine(Constants.FilePathUpload, targetFileName));

        file.Delete();
    }

 

Or use file.MoveTo

 

Regards,

Terry
