DependencyProperty SetValue和GetValue无法检测到silverlight [英] DependencyProperty SetValue and GetValue couldnt detect silverlight

问题描述

看似GetValue和SetValue（下面的粗体）可以在读取DependencyProperty之后检测到&bbsp; b $ p

It seems like the GetValue and SetValue (bolded below) could detect after having readonly DependencyProperty 

public bool TouchMove

public bool TouchMove

        {

            get {return（bool） GetValue （TouchMoveProperty）; }¥b $ b           设为

            {

SetValue （TouchMoveProperty，值）;



                if（value）

                    this.MoveChanged + = new TransformHandler（TouchElement_MoveChanged）;

               否则

                    this.MoveChanged - = new TransformHandler（TouchElement_MoveChanged）;

            }




$
        }




        public static readonly DependencyProperty TouchMoveProperty =

            DependencyProperty.Register（" TouchMove"，typeof（bool），typeof（TouchElement），new PropertyMetadata（false））;



        public delegate void TransformHandler（object sender，TransformEventArgs e）;



       公共事件TransformHandler MoveChanged;



        void TouchElement_MoveChanged（object sender，TransformEventArgs e）

        {

            var theMainWnd = Application.Current.RootVisual as MainPage;



           故事板myStoryboard =（故事板）（theMainWnd.FindName（" TransformImage"））;

            myStoryboard.Begin（）;

        }

        {
            get { return (bool)GetValue(TouchMoveProperty); }
            set
            {
SetValue(TouchMoveProperty, value);

                if (value)
                    this.MoveChanged += new TransformHandler(TouchElement_MoveChanged);
                else
                    this.MoveChanged -= new TransformHandler(TouchElement_MoveChanged);
            }



        }


        public static readonly DependencyProperty TouchMoveProperty =
           DependencyProperty.Register("TouchMove", typeof(bool), typeof(TouchElement), new PropertyMetadata(false));

        public delegate void TransformHandler(object sender, TransformEventArgs e);

        public event TransformHandler MoveChanged;

        void TouchElement_MoveChanged(object sender, TransformEventArgs e)
        {
            var theMainWnd = Application.Current.RootVisual as MainPage;

            Storyboard myStoryboard = (Storyboard)(theMainWnd.FindName("TransformImage"));
            myStoryboard.Begin();
        }
