In order to achieve your goal, you could create your own custom keyboard provider. Please refer to this help article for further details. Then you can predefine the behaviour for the Tab key overriding the ProvideCommandsForKey method similar to:
public override IEnumerable<
> ProvideCommandsForKey(Key key)
> commandsToExecute = base.ProvideCommandsForKey(key).ToList();
if (key == Key.Tab)
Club currentItem = parentGrid.CurrentItem as Club;
var currentColumn = parentGrid.CurrentColumn;
if ((currentItem != null) && (parentGrid.Items.IndexOf(currentItem) == (parentGrid.Items.Count-1)) && (currentColumn.DisplayIndex == parentGrid.Columns.Count - 2))
For your convinience, I have prepared a sample project that you can find attached.
I hope this helps.
