Silverlight之自定义Behavior

首先，请确保项目同时引用了 Microsoft.Expression.Interactions 和 System.Windows.Interactivity DLL。 自定义Behavior文件： MyBehavior.cs using System; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Ink;

　　

　　首先，请确保项目同时引用了 Microsoft.Expression.Interactions 和 System.Windows.Interactivity DLL。

　　自定义Behavior文件：

　　MyBehavior.cs

using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using System.Windows.Interactivity;

namespace behaviorTest
{
    public class MyBehavior:Behavior<TextBlock>
    {
        public MyBehavior()
        {
 
        }

        protected override void OnAttached()
        {
            base.OnAttached();
            AssociatedObject.MouseLeftButtonDown += new MouseButtonEventHandler(AssociatedObject_MouseLeftButtonDown);
        }

        void AssociatedObject_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            MessageBox.Show(AssociatedObject.Text.ToString());
        }

        protected override void OnDetaching()
        {
            base.OnDetaching();
            AssociatedObject.MouseLeftButtonDown-=new MouseButtonEventHandler(AssociatedObject_MouseLeftButtonDown);
        }

    }
}

　　前台页面：

<UserControl x:Class="behaviorTest.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas./markup-compatibility/2006"
    xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
    xmlns:my="clr-namespace:behaviorTest"
    mc:Ignorable="d"
    d:DesignHeight="300" d:DesignWidth="400">

    <Grid x:Name="LayoutRoot" Background="White">
        <TextBlock x:Name="tb" Text="HelloWorld" HorizontalAlignment="Center" VerticalAlignment="Center">
            <!--<i:Interaction.Behaviors>
                <my:MyBehavior />
            </i:Interaction.Behaviors>-->
        </TextBlock>
    </Grid>
</UserControl>

　　如果在后台加入Behavior的话，请看代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using System.Windows.Interactivity;
using Microsoft.Expression.Interactivity.Layout;

namespace behaviorTest
{
    public partial class MainPage : UserControl
    {
        public MainPage()
        {
            InitializeComponent();
            //自带的拖动行为
            //Interaction.GetBehaviors(tb).Add(new MouseDragElementBehavior());
            //自己定义的行为
            Interaction.GetBehaviors(tb).Add(new MyBehavior());
        }
    }
}
