Using SP2010: I added a column within the library so that I could display through different views. I can change the value stored in this column through using Library Tools -> Library -> Datasheet View. What I would like to do is to edit the form which appears when the user clicks on the "Add document" (green "+" sign) so users can change this when depositing a document. This would be easily done with a list, but I don't see the same option to edit the form in the library.
I looked at this URL: Editing a custom infopath form published to a library? but it doesn't help much because I'm not seeing any of the options it talks about. I do not find a "template.xsn" file in SPD under forms, just DispForm, EditForm, & Upload (all .aspx files).
Do I need to create a template.xsn file? If so, how do I go about doing so? Is there an easy (or easier) way to do this I'm missing? Thanks!
