Hello,

I like the idea of your ajaxuploader control but unfortunately I can’t get it work in my SharePoint 2010 environment. I use UploadAttachments control for C#.

Sometimes it works really good (I can upload the files and eg. Send them to SharePoint list as an attachments) but sometimes some strange things happens (and the issue occurs on different files, even on those which have been uploaded few clicks ago without any problems).

I’m using SharePoint 2010 foundation and the temporary license for your controls.

First issue:
I’m trying to upload file, progress bar appears but hangs and the following error appears. When I click OK and try to upload file again it sometimes works well but sometimes the same error appears.

When it fails the following icon appears

And another try:

Second issue:
Sometimes random files are uploaded with 0Bytes length. When I open the shared location where files are stored it has also 0Bytes while in explorer the file I want to upload has proper size.

File to upload in explorer:

I really like the control and would like to buy it but these errors are the real pain...

What can I do to resolve it?

Hello Ken,

there is no load balancing. The SharePoint is located on my laptop (development purposes only) and I'm using \\machinename\sharename.

Do you need some other information regarding my issue?

Please let me know.
