Just register PreviewKeyUp in one of the parent elements such as the DataGrid itself or the window, the Datagrid is within. Analye then the events OriginalSource to know from where the event has been coming.

To access the rows data you can do something like:

FrameworkElement fe=e.OriginalSource;
if(null != fe){
   YourRowDataObject rowData=fe.DataContext as YourRowDataObject;
   // work here with your data
}
