Caliburn笔记Action简写(wpf框架)

http://caliburn.codeplex.com/wikipage?title=Action%20Basics&referringTitle=Documentation

public void Demo()
{
    MessageBox.Show("hello");
}

1.传递方法

<Button Content="Demo"
        cal:Message.Attach="Demo" />

2.使用事件传递

(1)

<Button Content="Demo"
        cal:Message.Attach="[Event Click] = [Action Demo]" />

(2)附加事件(好像有bug)

<StackPanel cal:Message.Attach="[AttachedEvent Button.Click] = [Action Demo]">
    <Button Content="Divide (Stack)" />
    <Button Content="Divide (Stack)" />
</StackPanel>

3.事件连写(分号相隔)

<Button Content="Demo"
        cal:Message.Attach="[Event Click] = [Action Demo];[Event Loaded] = [Action Demo]" />

其他事件请参考此处

4.参数传递

(1)

public void Demo(string str)
{
    MessageBox.Show(str);
}

<Button Content="Demo"
        cal:Message.Attach="Demo('hello')" />

(2)支持元素对象获取

<TextBox x:Name="demoBox" />
<Button Content="Demo"
        cal:Message.Attach="Demo(demoBox.Text)" />

(3)支持内置参数解析

http://caliburn.codeplex.com/wikipage?title=Parameters&referringTitle=Documentation

public void Demo(object sender,EventArgs args)
{
   
}

<Button Content="Demo"
        cal:Message.Attach="Demo($source,$eventArgs)" />

(4)支持返回值传递

public int Demo()
{
    return 1;
}

<TextBox x:Name="demoBox" />
<Button Content="Demo"
        cal:Message.Attach="[Action Demo : demoBox.Text]" />

(5)支持绑定模式

<TextBox x:Name="demoBox" />
<Button Content="Demo"
        cal:Message.Attach="[Action Demo(demoBox.Text:TwoWay)]" />
