[Solved] Upload and Custom Metadata

[Marc Simkin]

I'm trying to figure out the best UI to design so that my users can associate custom metadata with the files being uploaded.  I know that the upload control supports sending custom metadata to the server.

I'm just having issues trying to decide how to design the UI.

If I use the upload control in async mode, and have a list to that contains metadata attributes, how can I make sure that the jQuery validation fires before the actual upload occurs?

Does it make sense to have the upload and metadata list inside it's own form tag?  Should it be a separate window, or can it be within another window/dialog?

Would it make more sense to do this as a grid with two columns, one for the meta data and one for the upload control?  Then there would be a one for one relationship with the upload control and the grid cell containing the meta data.

Any thoughts suggestions will be appreciated.

thanks

Hello Marc,

The use of an asynchronous upload in your scenario requires a bit of a mental shift. Submitting a form is no longer an atomic action from the servers point of view. It's more like a transaction. 

What we suggest is to:
    * Generate an unique ID for the current user
    * Store the uploaded files in a temporary location (using the unique ID)
    * Upon successful form submission move the files to their final destination

The upload and file metadata need not to be in a single form, as we have the unique ID to help us keep the association.

We have a code library that demonstrates the use of the Upload in Grid along with additional fields.

I hope this helps.
