Exemplos

Este exemplo mostra como aplicar um EntranceThemeTransition a um botão.

<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>

Aqui, o EntranceThemeTransition é aplicado usando um recurso 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>

Se você definir uma animação EntranceThemeTransition em um painel, os filhos do painel serão automaticamente deslocados quando eles animarem em exibição para criar uma entrada visualmente atraente.

Aqui, à medida que os retângulos são adicionados ao StackPanel, eles voam do canto superior direito, em vez de apenas aparecerem no lugar.

<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);
}
