用触发器更改内容按钮

Question

我希望在按下按钮时将按钮的内容更改为另一个图像但没有任何反应。

<Grid>
    <Button Height="120" Width="75">
        <Button.Template>
            <ControlTemplate TargetType="Button">
                <Image Source="no-press.png"/>
                <ControlTemplate.Triggers>
                        <Trigger Property="IsPressed" Value="True">
                            <Setter Property="Content">
                                <Setter.Value>
                                    <DataTemplate>
                                        <Image Source="press.png"/>
                                    </DataTemplate>
                                </Setter.Value>
                            </Setter>
                        </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Button.Template>      
    </Button>        
</Grid>
