If I understand well, perhaps something like
myDataGrid.SelectedItems=null
after selection changed could work if you just want to unselect the row.
Please mark as answered if it helped solving you problem

Sorry, Maybe I described is not clear enough
first select one row in datagrid,
when selecting another row, I want to cancel the selection, and still select the previous selected row

Unfortunately, this event does not exist today. In SL 3, you will be able to listen to the CurrentChanging event off of the CollectionView and cancel that. This will solve the problem for you in single selection but not for all multiple selection scenarios without doing some more work

Hi yifung, my datagrid itemsource is a ObservableCollection, how convert it to CollectionView type?

Unfortunately, you cannot convert from an ObservableCollection to a CollectionView. In Silverlight 3, there will be a public CollectionView available so you would create a CollectionView that wraps your ObservableCollection. Then, you would set the ItemsSource of the DataGrid to that CollectionView.

The Silverlight 3 Beta released in March. You could give that a try. As for the final Silverlight 3 release, I'm afraid I can't give any details. A lot of times for these things, the public rumors aren't too far off though.
