Capturing a title for each uploaded file

Reply Quote

Is it possible to display a text box (required field) for each uploaded file where the user can enter a title or caption? This title should be available in the code-behind so I can use it to store in my DB.

Re: Capturing a title for each uploaded file

Reply Quote

I've implemented the code above and changed it to use multiple files, but the "clientTable" never updates. The files are listed in the standard table with the checkbox/paperclip but it does have the textbox for the file description.

I'm using the Uploader and UploadAttachments within an asp.net wizard if that makes any difference.

Any ideas?
