Description: Runs after one or more items have been removed from the selected side of an IDList.
Execution: The visible lists have already been changed, but the new value has not yet been written to EntryData. The regular OnChange chain follows this event.
Arguments: Argument_SelectedIDList is a Variant array containing the complete remaining selected ID list after the change, not the removed IDs. It is Null when no selected items remain. The declared common event arguments are not populated by this executor.
Result: Any value assigned to Result is ignored.
Availability: Desktop only. Web remove operations update the value but do not execute OnRemoveItems.
Example: Detect removal of the last selected item.
if VarIsNull(Argument_SelectedIDList) then
ShowMessage("The selection is now empty");
