Ben sadece soldan akan metin, ve sağ tarafta bir yardım kutusu istiyorum.

Yardım kutusu altındaki tüm yol uzanır.

Eğer dış StackPanel aşağıda alırsan çok işe yarıyor.

Ama düzeni nedeniyle (UserControls dinamik olarak yerleştiriyorum) kaydırma StackPanel gerekiyor.

Nasıl denedim gördüğünüz gibi grup kutusu, StackPanel dibine kadar uzatmak için alıyorum:

• Ayarlar Verticalalignment="" Memnuniyetle
• VerticalContentAlignment="" Memnuniyetle
• Height="" . Otomatik

XAML:

<Window x:Class="TestDynamic033.Test3"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Test3" Height="300" Width="600">
    <StackPanel 
        VerticalAlignment="Stretch" 
        Height="Auto">

        <DockPanel 
            HorizontalAlignment="Stretch" 
            VerticalAlignment="Stretch" 
            Height="Auto" 
            Margin="10">

            <GroupBox 
                DockPanel.Dock="Right" 
                Header="Help" 
                Width="100" 
                Background="Beige" 
                VerticalAlignment="Stretch" 
                VerticalContentAlignment="Stretch" 
                Height="Auto">
                <TextBlock Text="This is the help that is available on the news screen." TextWrapping="Wrap" />
            </GroupBox>

            <StackPanel DockPanel.Dock="Left" Margin="10" Width="Auto" HorizontalAlignment="Stretch">
                <TextBlock Text="Here is the news that should wrap around." TextWrapping="Wrap"/>
            </StackPanel>

        </DockPanel>
    </StackPanel>
</Window>

Cevap:

Teşekkürler, StackPanel yerine DockPanel kullanarak o sorun çözüldü İşareti. Genel, DockPanel ve WPF layouting için iki tane daha, burada sabit XAML

<Window x:Class="TestDynamic033.Test3"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Test3" Height="300" Width="600" MinWidth="500" MinHeight="200">
    <DockPanel 
        VerticalAlignment="Stretch" 
        Height="Auto">

        <DockPanel 
            HorizontalAlignment="Stretch" 
            VerticalAlignment="Stretch" 
            Height="Auto" 
            MinWidth="400"
            Margin="10">

            <GroupBox 
                DockPanel.Dock="Right" 
                Header="Help" 
                Width="100" 
                VerticalAlignment="Stretch" 
                VerticalContentAlignment="Stretch" 
                Height="Auto">
                <Border CornerRadius="3" Background="Beige">
                    <TextBlock Text="This is the help that is available on the news screen." TextWrapping="Wrap" 

                Padding="5"/>
                </Border>
            </GroupBox>

            <StackPanel DockPanel.Dock="Left" Margin="10" Width="Auto" HorizontalAlignment="Stretch">
                <TextBlock Text="Here is the news that should wrap around." TextWrapping="Wrap"/>
            </StackPanel>

        </DockPanel>
    </DockPanel>
</Window>

Son unsur kalan tüm alanı kullanır StackPanel istediğiniz gibi geliyor. Ama neden DockPanel bir kullanım değil mi? ** 9, sonra da senin yardımınla DockPanel diğer elemanları kontrol süslemek kalan boşluğu doldurabilir.

XAML:

<DockPanel Width="200" Height="200" Background="PowderBlue">
    <TextBlock DockPanel.Dock="Top">Something</TextBlock>
    <TextBlock DockPanel.Dock="Top">Something else</TextBlock>
    <DockPanel
        HorizontalAlignment="Stretch" 
        VerticalAlignment="Stretch" 
        Height="Auto" 
        Margin="10">

      <GroupBox 
        DockPanel.Dock="Right" 
        Header="Help" 
        Width="100" 
        Background="Beige" 
        VerticalAlignment="Stretch" 
        VerticalContentAlignment="Stretch" 
        Height="Auto">
        <TextBlock Text="This is the help that is available on the news screen." 
                   TextWrapping="Wrap" />
     </GroupBox>

      <StackPanel DockPanel.Dock="Left" Margin="10" 
           Width="Auto" HorizontalAlignment="Stretch">
          <TextBlock Text="Here is the news that should wrap around." 
                     TextWrapping="Wrap"/>
      </StackPanel>
    </DockPanel>
</DockPanel>

Eğer DockPanel mevcut olmayan bir platform (örneğin WindowsStore), bir ızgara ile aynı etkiyi oluşturabilirsiniz. İşte yukarıdaki örnek yerine matrisini kullanarak yerine getirildi

<Grid Width="200" Height="200" Background="PowderBlue">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
    <StackPanel Grid.Row="0">
        <TextBlock>Something</TextBlock>
        <TextBlock>Something else</TextBlock>
    </StackPanel>
    <Grid Height="Auto" Grid.Row="1" Margin="10">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*"/>
            <ColumnDefinition Width="100"/>
        </Grid.ColumnDefinitions>
        <GroupBox
            Width="100"
            Height="Auto"
            Grid.Column="1"
            Background="Beige"
            Header="Help">
            <TextBlock Text="This is the help that is available on the news screen." 
              TextWrapping="Wrap"/>
        </GroupBox>
        <StackPanel Width="Auto" Margin="10" DockPanel.Dock="Left">
            <TextBlock Text="Here is the news that should wrap around." 
              TextWrapping="Wrap"/>
        </StackPanel>
    </Grid>
</Grid>
