Exemples

Cet exemple montre comment appliquer une entréeThemeTransition à un bouton.

<Button Content="EntranceThemeTransition Button">
    <Button.Transitions>
        <TransitionCollection>
            
            <!-- This transition just uses the default behavior which is to
                 have the button animate into view from the right. You can
                 make it start from anywhere on the right by using the
                 FromHorizontalOffset property. If you'd rather see a vertical
                 animation, use the FromVerticalOffset property. -->
            <EntranceThemeTransition />
        </TransitionCollection>
    </Button.Transitions>
</Button>

Ici, l’entréeThemeTransition est appliquée à l’aide d’une ressource Style.

<Grid Background="{StaticResource ApplicationPageBackgroundBrush}">
    <Grid.Resources>
        <Style x:Key="DefaultButtonStyle" TargetType="Button">
            <Setter Property="Transitions">
                <Setter.Value>
                    <TransitionCollection>
                        <EntranceThemeTransition/>
                    </TransitionCollection>
                </Setter.Value>
            </Setter>
        </Style>
    </Grid.Resources>

    <Button Style="{StaticResource DefaultButtonStyle}" 
            Content="EntranceThemeTransition style applied" />

</Grid>

Si vous définissez une animation EntranceThemeTransition sur un panneau, les enfants du panneau sont automatiquement décalés lorsqu’ils s’animent en mode pour créer une entrée visuellement attrayante.

Ici, à mesure que des rectangles sont ajoutés à StackPanel, ils volent à partir du coin supérieur droit, plutôt que de simplement apparaître en place.

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <Button Content="Add rectangle" Click="Button_Click"/>

    <StackPanel x:Name="panel1" HorizontalAlignment="Left" Margin="200">
        <StackPanel.ChildrenTransitions>
            <TransitionCollection>
                <EntranceThemeTransition 
                FromHorizontalOffset="200" 
                FromVerticalOffset="-200"/>
            </TransitionCollection>
        </StackPanel.ChildrenTransitions>
    </StackPanel>
</Grid>

private void Button_Click(object sender, RoutedEventArgs e)
{
    // Add a rectangle to the StackPanel.
    Rectangle r = new Rectangle();
    r.Width = 100;
    r.Height = 100;

    // Alternate colors as rectangles are added.
    if (panel1.Children.Count % 2 == 0)
    {
        r.Fill = new SolidColorBrush(Colors.Green);
    }
    else
    {
        r.Fill = new SolidColorBrush(Colors.Yellow);
    }
    panel1.Children.Add(r);
}
