When I'm uploading file from lightning out (apex page) and attach it to my record in Notes & Attachments related list salesforce doesn't show file size. It shows only when I'm uploading from salesforce page. How to show file size?enter image description here

  • are you talking about the standard related list? Can you add a screenshot? Jun 26, 2020 at 14:24
  • @sanketkumar just added. Yes it's standard related list Jun 26, 2020 at 14:28
  • how are you uploading the file using lightning:out? Can you add the minimal required as well? Jun 26, 2020 at 14:37
  • @sanketkumar I'm uploading file as attachment from vf page, but when I'm uploading file inside salesforce it upload file as ContentDocument. I guess it's main problem and I need to upload file like ContentDocument Jun 26, 2020 at 14:45
  • That is indeed correct, Files and Attachments are shown in different way in Related list on record

Bodylength - Size of the file (in bytes) of the attachment.

Unfortunately, You cannot add this field on notes and attachment-related list as this is not customizable.

The workaround is you can create a simple custom Lightning Component to show attachment as a table.
