VerticalScrollBarVisibility fonctionne quand je le définir en ligne comme ceci:Pourquoi VerticalScrollBarVisibility ne fonctionne pas dans un style dans Silverlight?
<UserControl x:Class="TestScrollBar.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006">
<UserControl.Resources>
<Style TargetType="TextBox" x:Key="EditListContainerContentMultiLineTwoColumn">
<Setter Property="AcceptsReturn" Value="True"/>
<Setter Property="Width" Value="400"/>
<Setter Property="Height" Value="300"/>
<Setter Property="IsReadOnly" Value="False"/>
<Setter Property="Margin" Value="0 0 0 20"/>
<Setter Property="HorizontalAlignment" Value="Left"/>
<Setter Property="TextWrapping" Value="Wrap" />
</Style>
</UserControl.Resources>
<Grid x:Name="LayoutRoot" Background="White" Margin="10">
<StackPanel HorizontalAlignment="Left">
<TextBox Text="this is a test"
Style="{StaticResource EditListContainerContentMultiLineTwoColumn}"
VerticalScrollBarVisibility="Auto"
/>
</StackPanel>
</Grid>
</UserControl>
Mais quand je mets VerticalScrollBarVisibility dans un style, il me montre un écran vide:
<UserControl x:Class="TestScrollBar.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006">
<UserControl.Resources>
<Style TargetType="TextBox" x:Key="EditListContainerContentMultiLineTwoColumn">
<Setter Property="VerticalScrollBarVisibility" Value="Auto"/>
<Setter Property="AcceptsReturn" Value="True"/>
<Setter Property="Width" Value="400"/>
<Setter Property="Height" Value="300"/>
<Setter Property="IsReadOnly" Value="False"/>
<Setter Property="Margin" Value="0 0 0 20"/>
<Setter Property="HorizontalAlignment" Value="Left"/>
<Setter Property="TextWrapping" Value="Wrap" />
</Style>
</UserControl.Resources>
<Grid x:Name="LayoutRoot" Background="White" Margin="10">
<StackPanel HorizontalAlignment="Left">
<TextBox Text="this is a test"
Style="{StaticResource EditListContainerContentMultiLineTwoColumn}"
/>
</StackPanel>
</Grid>
</UserControl>
En WPF cela fonctionne fonctionne très bien.
Comment puis-je faire fonctionner VerticalScrollBarVisibility dans un style?
