Hi Chris,
Thanks a lot for your response. Your solution worked for me. I used ListPreviewPane in place of the modal dialog to contain the Attachments reuse component. And as suggested by you, I bound the Attachments EC to the DataList. I am now able to save attachments per row in the DataList.
Any idea on why the attachment reuse component doesn't allow to be bound on to anything other than the Root node when it is placed inside a modal dialog?
Thanks,
Sanat
