c# – 单击WPF图像的事件

<Window ...>
    <Window.Resources>
        <Style TargetType="{x:Type Button}" x:Key="ImageButtonStyle">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type Button}">
                        <ContentPresenter/>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Window.Resources>
    <Button Style="{StaticResource ImageButtonStyle}" Click="ImageButton_Click">
        <Image Source="..."/>
    </Button>
</Window>

使用上面的XAML Image将是你的Button

下面你可以找到如何绑定/更改Image.Source的简化版本,其中所有内容都在MainWindow中完成,但基本上在WPF中你不操纵控件但是使用Binding绑定它们的属性并操纵这些属性.通常,您将创建专用类(ViewModel).你的类需要实现INofityPropertyChanged接口,需要相应地设置DataContext,每次更改值时绑定属性需要引发INofityPropertyChanged.PropertyChanged事件(这就是你通知UI刷新值的方式)

public partial class MainWindow : Window,INotifyPropertyChanged
{
   public MainWindow()
   {
      InitializeComponent();
      DataContext = this;
   }

   private ImageSource _myImageSource;

   public ImageSource MyImageSource
   {
      get { return _myImageSource; }
      set
      {
          _myImageSource = value;
          OnPropertyChanged("MyImageSource");
      }
   }

   private void ImageButton_Click(object sender,RoutedEventArgs e)
   {
       this.MyImageSource = new BitmapImage(...); //you change source of the Image
   }

   public event PropertyChangedEventHandler PropertyChanged;

   private void OnPropertyChanged(string propertyName)
   {
      var handler = PropertyChanged;
      if (handler != null) handler(this,new PropertyChangedEventArgs(propertyName));
   }    
}

在XAML中：

<Button Style="{StaticResource ImageButtonStyle}" Click="ImageButton_Click" Width="..." Height="...">
    <Image Source="{Binding MyImageSource}"/>
</Button>
