I'm trying to set up a 1:Many relationship between items in a parent list.
In the EditForm for the parent item, I've inserted a XsltListViewWebPart for the child list, and set up filtering on the parent ID. This is working well so far, however my issue is with adding a new item to child list. I would like the parent ID to be passed into it the new child item.
I've seen some guides on how to do this with using the query string when a new dialog/page is opened, but I would like to do "inline editing". I'm assuming I can just write a javascript function to populate the column, but I'm not sure where I can hook it into.
I'm new to this, so I could be on the wrong track altogether too.
