Hi Keisuke, thanks for your response….  Just trying to get clarification here.

In the 4D Design Reference documentation, in the List Boxes section, it clearly 
states that:
"A button or a menu item associated with the Delete Subrecord standard action 
is automatically enabled when there is at least one row selected in a 
"selection" type list box. When multiple rows are selected, the action is 
applied to all the records. When a user clicks on the button or selects the 
menu item, a confirmation dialog box appears so that the user can confirm or 
cancel the deletion…"

Using standard actions

Are you saying the documentation is incorrect?

My understanding is that the current selection of a list form (sub form) are 
the related records…. And that if the action was to only work on the current 
selection then it would be “Delete Record” not "Delete SubRecord” both of which 
seem to be valid if I’m understanding the documentation correctly.

Thanks,
