You can use the SelectedItem property to get the currently selected object, which you can then cast into the correct type. For instance, if your DataGrid is bound to a collection of Customer objects you could do this:

Customer customer = (Customer)myDataGrid.SelectedItem;

Alternatively you can bind SelectedItem to your source class or ViewModel.

<Grid DataContext="MyViewModel">
    <DataGrid ItemsSource="{Binding Path=Customers}"
              SelectedItem="{Binding Path=SelectedCustomer, Mode=TwoWay}"/>
</Grid>
