[ASP.net教程]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);    }
