The AJAXUploader is not completing the file upload correctly. For example, if I upload an image, only the top portion of the image uploads. Everything appears to have uploaded correctly, but opening the image on the server shows only the top portion.
I did not install on the server, just my machine. So, I copied the EO.Web.dll to the bin directory, and the eo_web.ashx file to the root directory of the website.

             <asp:Label ID="lblStatus" runat="server" />
          </eo:CallbackPanel> 
     
 
Code Behind:
    
        Code: C#
        
        protected void finishedUploading(object sender, EventArgs e)
    {
       EO.Web.AJAXPostedFile[] files = au1.PostedFiles;
       StringBuilder str = new StringBuilder();
       foreach (EO.Web.AJAXPostedFile file in files)
       {
          str.Append(System.IO.Path.GetFileName(file.TempFileName) + "<br/>");
          string tmpFileName = file.TempFileName;
          string finalFilename = System.IO.Path.Combine(Server.MapPath("/test/"), file.ClientFileName);
          System.IO.File.Move(tmpFileName, finalFilename);
       }
       lblStatus.Text = str.ToString();
    } 
     
 
As you can see I'm copying the uploaded file to a new folder and using the AJAXPostedFile functionality to save it as the original file type. I then open the file on the server itself.
