如何将行为添加到我的Xaml中的控件，但仅针对特定平台？

<Grid>
    <VisualStateManager.VisualStateGroups>
        <VisualStateGroup x:Name="PlatformStates">
            <VisualState x:Name="WindowsState">
                <!-- Windows平台的控件外观和行为 -->
            </VisualState>
            <VisualState x:Name="AndroidState">
                <!-- Android平台的控件外观和行为 -->
            </VisualState>
        </VisualStateGroup>
    </VisualStateManager.VisualStateGroups>

    <!-- 控件的定义 -->
</Grid>

<Grid>
    <VisualStateManager.VisualStateGroups>
        <!-- 可视状态的定义 -->
    </VisualStateManager.VisualStateGroups>

    <Button Content="按钮">
        <Button.Triggers>
            <EventTrigger SourceName="myControl" EventName="Loaded">
                <Trigger.Targets>
                    <Setter TargetName="myControl" Property="Visibility" Value="Visible"/>
                </Trigger.Targets>
            </EventTrigger>
        </Button.Triggers>
    </Button>
</Grid>
