Soution: define globally DataGrid dgrdRowDetail;

in event parent event we can fine the child data grid and then define the event for the child data grid to.

   private void dgCounty_RowDetailsVisibilityChanged(object sender, DataGridRowDetailsEventArgs e)
            {            
           dgrdRowDetail = (DataGrid)e.DetailsElement.FindName("dgrdRowDetail");
             dgrdRowDetail.RowDetailsVisibilityChanged+=new EventHandler<DataGridRowDetailsEventArgs>(dgrdRowDetail_RowDetailsVisibilityChanged);
    }

once you get your dgrdRowDetail which is the child control then yoy can perform all the actions against it like binding,events all those stuff.
