Upload and download multiple documents in same interface

Hi Chandra,
Hope you got answer from the previous Post,
Appian Documents will be stored in KC only after form Submission So Uploading a document without Form submission is not possible.
You can do the following:
Create an Interface with A file upload field and And an Upload button of type Submit. When user submits Upload button loop it back to Same Interface displaying the documents in Grid.
Have a paging Grid right below the file upload button, display the document details. You can configure this conditionally to show only when documents are available.
Hope this helps.
