In your Datagrid 2 Configuration you will find the OnClick Event.
This will be triggered when clicking on a row.
Set a call nanoflow and pass the paramter to the js action
Hope this helps,
If you really need double click you can look into the Doubleclick trigger widget (link). You can place this widget in one or multiple columns. You can use it to trigger a nanoflow that takes the row object as input.
