ADD. RadDock - functionality to change the text orientation of the AutoHideTab Comment: The text of AutoHideTab can be flipped for achieving of these requirements as the following code snippet demonstrates: private void radDock1_TransactionCommitted(object sender, RadDockTransactionEventArgs e) { if (e.Transaction is AutoHideTransaction) { foreach (DockWindow window in e.Transaction.AssociatedWindows) { window.AutoHideTab.FlipText = true; window.AutoHideTab.TextAlignment = ContentAlignment.MiddleCenter; } } }
