Silverlight杂记-behaviors

 

使用已经存在的behaviors

1引入DLL

2在XAML中添加行为，

在这里添加了2个，一个是拖动，一个是缓动效果

<Rectangle x:Name="PurpleSquare" 
                Height="20" 
                Width="20" 
                HorizontalAlignment="Left" 
                VerticalAlignment="Top" 
                Margin="20" 
                Fill="BlueViolet"> 
        <i:Interaction.Behaviors>
           <ei:MouseDragElementBehavior> 拖拽效果行为
               </ei:MouseDragElementBehavior>

            <ei:FluidMoveBehavior Duration="0:0:4">缓动 
                <ei:FluidMoveBehavior.EaseX> 
                    <ElasticEase EasingMode="EaseOut" 
                                    Oscillations="3" 
                                    Springiness="4" /> 
                </ei:FluidMoveBehavior.EaseX> 
                <ei:FluidMoveBehavior.EaseY> 
                    <ElasticEase EasingMode="EaseOut" 
                                    Oscillations="3" 
                                    Springiness="4" /> 
                </ei:FluidMoveBehavior.EaseY> 
            </ei:FluidMoveBehavior> 
        </i:Interaction.Behaviors>

 

private void StartMove_Click(object sender, RoutedEventArgs e) { 
         Thickness margin = PurpleSquare.Margin; 
         margin.Left += 100; 
         margin.Top += 100;
         PurpleSquare.Margin = margin; 
     }

 

 

 

自定义behaviors

public class CustomBehavior : Behavior<Button>
  {
      protected override void OnAttached()
      {
          base.OnAttached();
          AssociatedObject.Click += new RoutedEventHandler(OnButtonClick);
      }

      protected override void OnDetaching()
      {
          base.OnDetaching();
          AssociatedObject.Click -= OnButtonClick;
      }

      void OnButtonClick(object sender, RoutedEventArgs e)
      {
          MessageBox.Show("自定义行为-！  MessageBox.Show");
      }
  }
