in phpmake 10 PreviewRow & PreviewOverlay show together but in phpmaker 12 One of PreviewRow or PreviewOverlay show .
how i am can show PreviewRow & PreviewOverlay together like v10 in v12 ?
You still have both in v12. Note that the button for Preview Overlay is the dropdown button (if "Use button dropdown for links" is enabled) or the button for the detail table (if "Use button dropdown for links" is disabled). If PreviewRow is enabled, the links to access to detail table is in the preview row, so the columns for the detail tables are made hidden by default and without the column (and the button inside it), the Preview Overlay has no button to attach to. You can however set the column as visible in ListOptions_Rendered server event (see Server Events and Client Scripts in the help file), e.g.
$this->ListOptions->Items["detail_<detailtable>"]->Visible = TRUE; // replace <detailtable> by your detail table name
