WinForm 加载 WPF控件 怎么在winform里面得到控件的触发事件？

Question

Winform： private WPFButton wpfButton1;
            this.elementHost2.AutoSize = true;
            this.elementHost2.BackColor = System.Drawing.Color.Transparent;
            this.elementHost2.ForeColor = System.Drawing.Color.Transparent;
            this.elementHost2.Location = new System.Drawing.Point(110, 284);
            this.elementHost2.Name = "elementHost2";
            this.elementHost2.Size = new System.Drawing.Size(196, 52);
            this.elementHost2.TabIndex = 3;
            this.elementHost2.Text = "elementHost2";
            this.elementHost2.Child = this.wpfButton1;
WPF控件貌似只能在自己那儿获取事件啊？ <Grid Height="52" Width="196" Opacity="0.5">
        <Button HorizontalAlignment="Right" Style="{DynamicResource GlassButtonStyle}" VerticalAlignment="Top" Width="190" Height="52" Content="Button" Foreground="#FFFFFFFF" Click="Button_Click" />
    </Grid>

Answer 1

<Button x:Name="DrawButton" Height="40" Width="120" 
VerticalAlignment="Top" 
HorizontalAlignment="Left">
Click="DrawButton_Click"
</Button>
private void DrawButton_Click(object sender, RoutedEventArgs e)
{}

Answer 2

这个事件还是在控件里面发生的啊~怎么返回给winform窗体？DrawButton类里面不能再申明个winform类吧？

Answer 3

DrawButton_Click 方法不是写在Winform窗体类里面吗？ 方法里的this不就是winform

Answer 4

WPFButton是自定义控件~
另外一个类
 public partial class WPFButton : UserControl
    {
        public WPFButton()
        {
            InitializeComponent();
        }        public void Button_Click(object sender, RoutedEventArgs e)
        {
        }
    }

Answer 5

Winform里不能注册这个Button的Click事件？最差最差，在Button里暴露个Event总是可以的吧。public partial class WPFButton : UserControl
    {
        public WPFButton()
        {
            InitializeComponent();
        }        public EventHandler Click;        public void Button_Click(object sender, RoutedEventArgs e)
        {
             if (Click != null)
                Click(sender, e);
        }
    }
呆会我试试。

Answer 6

public event EventHandler Click;

Answer 7

WpfButton 代码：public event EventHandler MyWpfButtonClick;private void button1_Click(object sender, RoutedEventArgs e)
{
    if (MyWpfButtonClick != null)
        MyWpfButtonClick(sender, e);
}
使用的Form：private void Form1_Load(object sender, EventArgs e)
{
    this.myWpfButton1.MyWpfButtonClick += new EventHandler(myWpfButton1_MyWpfButtonClick);
}void myWpfButton1_MyWpfButtonClick(object sender, EventArgs e)
{
     MessageBox.Show("MyWpfButtonClick");
}

Answer 8

其实问题在于，你封装的是UserControl，Button只是用户控件里的一个子控件。
只要在WPF自定义控件类里，暴露这个Button就可以了。这样也不用封装Event了。public Button WpfButton
{
    get { return this.button1; }
}
Winform：private void Form1_Load(object sender, EventArgs e)
{
    //this.myWpfButton1.MyWpfButtonClick += new EventHandler(myWpfButton1_MyWpfButtonClick);
    this.myWpfButton1.WpfButton.Content = "Hello";
    this.myWpfButton1.WpfButton.Click += new System.Windows.RoutedEventHandler(WpfButton_Click);
}void WpfButton_Click(object sender, System.Windows.RoutedEventArgs e)
{
    MessageBox.Show("MyWpfButton.Button.Click");
}

Answer 9

按fangxinggood的做法应该就可以了吧，个人建议使用事件传递public partial class WPFButton : UserControl
    {
        public WPFButton()
        {
            InitializeComponent();
        }        public event EventHandler<EventArgs> WPFButtonClick;        public void Button_Click(object sender, RoutedEventArgs e)
        {
            EventHandler<EventArgs> handler = WPFButtonClick;
            if (handler != null)
                handler(sender, e);
        }
    }
