Hosting code registration mouse events

You do not need to declare registration events in. xaml.

. Xaml

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

Different from registering an event in. xaml

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

 

Then, register the mouse event in. c # and place it in MainPage.

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);
     }

When obtaining the time, you can

Ellipse. MouseEnter + = directly attach the 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);        }
