silverlight 鼠标事件处理

托管代码注册鼠标事件

不需要再.xaml中声明注册事件。

.xaml

 <Ellipse Name="ellipse" Width="120" Height="120" Fill="Orange"
                     Canvas.Top="60" Canvas.Left="80"/>

区别于在.xaml中注册事件

 <Ellipse Name="ellipse" Width="120" Height="120" Fill="Orange"
                     Canvas.Top="60" Canvas.Left="80" MouseEnter="OnMouseEnter"/>

然后再.c# 中进行鼠标事件的注册，放在MainPage 中

public MainPage()
        {
            InitializeComponent();

            ellipse.MouseEnter += new MouseEnterHander(OnMouseEnter);
            ellipse.MouseLeave += new MouseEnterHander(OnMouseEnter);       }

void OnMouseEnter(object sender, MouseEventArgs e)     {        Ellipse m = sender as Ellipse;        m.Fill=new SolidColorBrush(Color.Green);     }

在获取时间的时候可以在

 ellipse.MouseEnter +=   直接连击Tab  

 public MainPage()
        {
            InitializeComponent();

            ellipse.MouseEnter += Ellipse_MouseEnter;
            ellipse.MouseLeave += Ellipse_MouseLeave;

        }

    private void Ellipse_MouseLeave(object sender,MouseEventArgs e)
        {
            Ellipse ell = sender as Ellipse;
            ell.Fill = new SolidColorBrush(Colors.Gray);
        }
    private void Ellipse_MouseEnter(object sender, MouseEventArgs e)
        {
            Ellipse ell = sender as Ellipse;
            ell.Fill = new SolidColorBrush(Colors.Black);
        }
