[WPF] 특정 컨트롤 Size 변경될 시, 값 가지고 오기

ElementName에 추적하고 싶은 컨트롤 이름 물리고 땡겨오면 된다.

<UserControl.Resources>
    <converter:MultiInputConverter x:Key="multiParam"/>
</UserControl.Resources>

<i:Interaction.Triggers>
    <i:EventTrigger EventName="SizeChanged">
        <i:InvokeCommandAction Command="{Binding VIewSizeChangeCommand}">
            <i:InvokeCommandAction.CommandParameter>
                <MultiBinding Converter="{StaticResource multiParam}">
                    <Binding Path="ActualWidth" ElementName="hvView"/>
                    <Binding Path="ActualHeight" ElementName="hvView"/>
                </MultiBinding>
            </i:InvokeCommandAction.CommandParameter>
        </i:InvokeCommandAction>
    </i:EventTrigger>
    <i:EventTrigger EventName="Loaded">
        <i:InvokeCommandAction Command="{Binding VIewSizeChangeCommand}">
            <i:InvokeCommandAction.CommandParameter>
