Synchronizing two BindingSources

I have a form with a DataGridView that opens a details form on a double click.
When opening the second form I set it to use the same DataSet instance as the parent form. i now want to make sure the second form is pointing at the same DataRow as the parent as well.
At first I just sent in the Position property of the parent form's BindingSource, and set the same property on the BindingSource of the details form. This worked just fine until I started sorting the DataGridView - now the parent's position is showing the sorted value, and all hell breaks loose.
I then tried sending in the actual DataRow and even the DataRowView object of the parent BindingSource, and using the Find method on the details BindingSource - but they all just return -1.
What other way I can use to set the BindingSource Current property, if I can't relay on indexes or on values? Do I have to use the Filter method and construct a filter query dynamically (I have multiple properties for PK, so I can't just use Find)?

You can iterate through DataRows in BindingSource to find selected one.
