I am using SharePoint online for work. I have a subsite with 2 WebParts, both of which are lists (XsltListViewWebPart). Each list has folders, with each folder having a number of documents within.
I'd like the 'modified' date on the list with the folders to reflect the date that the most recent item within that folder was modified, not the date the folder was modified (meaning if I chose to re-name it or something).
I have done many searches, and the most closely related post I've found is here: Showing Folder's modified date as most recently edited documents's modified date in that folder ...And it has gone unanswered for 3 years.
Any help or suggestions are appreciated.
