Examples

This example shows how to use multiple Setter statements inside the VisualState.Setters property to apply discrete property value changes on various elements (without animations) when a VisualState is applied.

<Page>
    <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <VisualStateManager.VisualStateGroups>
            <VisualStateGroup>
                <VisualState x:Name="NarrowState">
                    <VisualState.Setters>
                        <Setter Target="myPanel.Orientation" Value="Vertical"/>
                        <Setter Target="myPanel.Width" Value="380"/>
                        <Setter Target="myTextBlock.MaxLines" Value="3"/>
                    </VisualState.Setters>
                </VisualState>
            </VisualStateGroup>
        </VisualStateManager.VisualStateGroups>

        <StackPanel x:Name="myPanel" Orientation="Horizontal">
            <TextBlock x:Name="myTextBlock" MaxLines="5" Style="{ThemeResource BodyTextBlockStyle}"/>
        </StackPanel>
    </Grid>
</Page>

To update a value of an attached property, place the attached property path inside parentheses. This example shows how to update the RelativePanel.AlignRightWithPanel value on an element with the name 'TitleTextBlock'.

<RelativePanel>
    <TextBlock x:Name="TitleTextBlock" Text="Title"/>
</RelativePanel>

...

<Setter Target="TitleTextBlock.(RelativePanel.AlignRightWithPanel)" Value="True"/>

Remarks

The Setter.Target property can be used in either a Style or a VisualState, but in different ways.

When used in a Style, the property that needs to be modified can be specified directly.
When used in VisualState, the Target property must be given a TargetPropertyPath (dotted syntax with a target element and property explicitly specified).
