MVVM EventToCommand未找到 [英] MVVM EventToCommand not found

问题描述

大家好，我想在一个列表框的项目点击效果器的，但我不断收到此错误：

Hi all I am trying to implement an on click effect in the items of a listbox but I keep getting this error:

键入CMD：EventToCommand是未找到。 。确保你是不是缺少程序集引用，并且所有引用的程序已建成

The type 'cmd:EventToCommand' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.

<catel:UserControl

         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

         mc:Ignorable="d" 
         d:DesignHeight="300" d:DesignWidth="300">

和在那里我尝试实施上点击方法的代码：

And the code where I try to implement the on click method:

<Grid>
    <ItemsControl ItemsSource="{Binding Source={StaticResource cvsRoutes}}">
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <Expander Header="{Binding Name}" MinHeight="50">
                    <ListBox>
                        <i:Interaction.Triggers>
                            <i:EventTrigger EventName="PreviewMouseLeftButtonDown">
                                <cmd:EventToCommand Command="{Binding PreviewMouseLeftButtonDownCommand}" PassEventArgsToCommand="True"/>
                            </i:EventTrigger>
                        </i:Interaction.Triggers>
                        <TextBlock Text="Something" >
                        <i:Interaction.Triggers>
                            <i:EventTrigger EventName="KeyUp">
                                <cmd:EventToCommand Command="{Binding KeyUpCommand}" PassEventArgsToCommand="True"/>
                            </i:EventTrigger>
                        </i:Interaction.Triggers>
                        </TextBlock>
                        <TextBlock Text="Something" />
                        <TextBlock Text="Something" />
                        <TextBlock Text="Something" />
                        <TextBlock Text="Something" />
                    </ListBox>
                </Expander>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>
</Grid>

您能告诉我是什么问题以及如何解决这个问题？

Can you tell me what is the problem and how can I fix it?

推荐答案

有是，在Catel可用，如何使用他们的所有行为和触发器的一个很好的列表：

There is a good list of all behaviors and triggers that are available in Catel and how you can use them:

还包括EventToCommand：

It also includes EventToCommand:
