WPF命令绑定汇总

1、Button等自带Command属性的控件，直接绑定命令

<Button HorizontalAlignment="Left" Width="105" Height="32"Command="{Binding ClickCommand}">
     <TextBlock Text="点击" Foreground="#555555"></TextBlock>
</Button>

 

2、Microsoft.Xaml.Behaviors.Wpf包，可通过Nuget获取

添加引用

xmlns:b="http://schemas.microsoft.com/xaml/behaviors"

XAML中调用：

<b:Interaction.Triggers>
        <b:EventTrigger EventName="Loaded">
            <b:InvokeCommandAction Command="{Binding LoadedCommand}" PassEventArgsToCommand="True"></b:InvokeCommandAction>
        </b:EventTrigger>
</b:Interaction.Triggers>

 

3、System.Windows.Interactivity.WPF包，可通过Nuget获取（和第二种方式类似）

添加引用

xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
或者
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"

XAML中调用：

    <i:Interaction.Triggers>
        <i:EventTrigger EventName="MouseMove">
            <i:InvokeCommandAction Command="{Binding Command2}" CommandParameter="{Binding ElementName=btn}" />
        </i:EventTrigger>
    </i:Interaction.Triggers>

 

4、KeyBinding，用来绑定鼠标、键盘点击事件

<Window.InputBindings>
        <KeyBinding Key="Enter" Command="{Binding SendCommand}" />
    </Window.InputBindings>
