FocusNavigationDirection.Next未移至Next Control

Question

TraversalRequest request = new TraversalRequest(FocusNavigationDirection.Next);                    
MoveFocus(request);

我在DataGrid PreviewKeyDown事件中使用此代码，而Focus并未转移到Next Control，而是将其焦点转移到DataGrid之前的Two Control。

Answer 1

将此代码用于请求：

TraversalRequest request = new TraversalRequest(FocusNavigationDirection.Down);

请求使用关闭 希望有帮助
