处理Button的ListView中的Click命令

假设我有一个简单的ListView,其中只有一个按钮,它是Gridview的唯一一栏:

<ListView x:Name="SomeListView" ItemsSource="{Binding Whatever}">
    <ListView.View>
        <GridView>
             <GridViewColumn CellTemplate="{StaticResource myCellTemplate}" Header="ColumnHeader"/>
        </GridView>
    </ListView.View>
</ListView>

myCellTemplate看起来像这样:

<DataTemplate x:Key="myCellTemplate">
    <Viewbox>
        <Button x:Name="mybutton" Command="{Binding myClickCommand}" Content="{Binding btnBinding}"></Button>
    </Viewbox>
</DataTemplate>

myClickCommand在我的VM中使用ICommand。此时,一切都很糟糕,用户点击我的按钮会调用myClickCommand,如你所料。现在,我想在我的行中添加一些鼠标悬停样式,所以我添加了一个ItemContainerStyle,如下所示:

<ListView x:Name="SomeListView" ItemContainerStyle="{StaticResource myItemStyle}" ItemsSource="{Binding Whatever}">
    ...
</ListView>

myItemStyle为:

<Style x:Key="myItemStyle" TargetType="{x:Type ListViewItem}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ListViewItem}">
                <Grid>
                    <Border x:Name="borderMain" BorderThickness="1" BorderBrush="Transparent">
                        <GridViewRowPresenter VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                    </Border>
                    <Rectangle x:Name="rectGlass" Fill="LightGray" Opacity=".2" Visibility="Hidden"></Rectangle>
                </Grid>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsMouseOver" Value="true">
                        <Setter TargetName="borderMain" Property="BorderBrush" Value="DarkGray" />
                        <Setter TargetName="rectGlass" Property="Visibility" Value="Visible"/>
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

此时,用户的点击不会触发myClickCommand,可能是因为事件没有路由到按钮。有没有办法实现这个目标?

您的Rectangle(rectGlass)位于Button的顶部。该按钮未收到点击事件,因为它实际上从未被点击过。
