1、窗体基类实现参考

2、基类不能像WinForm窗体一样写Loaded事件（写了也是不执行的）

没办法只好写一个方法让所有继承者调用了

3、回车键改为TAB的实现

        /// <summary>

        /// 将回车改为TAB

        /// </summary>

        /// <param name="e"></param>

        protected override void OnKeyDown(System.Windows.Input.KeyEventArgs e)

        {

            if (e.Key == System.Windows.Input.Key.Enter)

            {

                // MoveFocus takes a TraveralReqest as its argument.

                TraversalRequest request = new TraversalRequest(FocusNavigationDirection.Next);

                // Gets the element with keyboard focus.

                UIElement elementWithFocus = Keyboard.FocusedElement as UIElement;

                // Change keyboard focus.

                if (elementWithFocus != null)

                {

                    elementWithFocus.MoveFocus(request);

                }

                e.Handled = true;

            }

            base.OnKeyDown(e);

        }
