如何从 WPF 中的 ListBox 中删除边框?
How to remove border from ListBox in WPF?
这是我的代码:
<Grid>
<ScrollViewer Grid.Row="0" Grid.Column="1" HorizontalScrollBarVisibility="Disabled">
<StackPanel Orientation="Vertical">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Left">
<TextBox MinWidth="80" Name="tbTodoName" Margin="5, 2"/>
<Button Content="Add" Height="30" Margin="5, 0"/>
</StackPanel>
<ListBox Name="lstTodo" ItemsSource="{Binding}" BorderThickness="0" Padding="0" ItemTemplate="{StaticResource TodoTemplate}" ScrollViewer.HorizontalScrollBarVisibility="Disabled" HorizontalAlignment="Stretch">
</ListBox>
</StackPanel>
</ScrollViewer>
</Grid>
这是程序的图片:
如图所示,ListBox周围出现了一个框。我不明白为什么,因为我设置了 BorderThickness 和 Padding = "0"。
有人可以帮助我吗?
您已经设置了一个自定义的 ItemTemplate,它只应用于项目。
您还需要应用模板:
<Grid>
<ScrollViewer Grid.Row="0" Grid.Column="1" HorizontalScrollBarVisibility="Disabled">
<StackPanel Orientation="Vertical">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Left">
<TextBox MinWidth="80" Name="tbTodoName" Margin="5, 2"/>
<Button Content="Add" Height="30" Margin="5, 0"/>
</StackPanel>
<ListBox Name="lstTodo" ItemsSource="{Binding}" BorderThickness="0" Padding="0" ItemTemplate="{StaticResource TodoTemplate}" Template={StaticResource ListBoxNoBorder}
ScrollViewer.HorizontalScrollBarVisibility="Disabled" HorizontalAlignment="Stretch">
</ListBox>
</StackPanel>
</ScrollViewer>
</Grid>
并且在您的资源字典中:
<ControlTemplate x:Key="ListBoxNoBorder" TargetType="{x:Type ListBox}">
<Border BorderBrush="Transparent" BorderThickness="0">
<ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Border>
</ControlTemplate>
这是我的代码:
<Grid>
<ScrollViewer Grid.Row="0" Grid.Column="1" HorizontalScrollBarVisibility="Disabled">
<StackPanel Orientation="Vertical">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Left">
<TextBox MinWidth="80" Name="tbTodoName" Margin="5, 2"/>
<Button Content="Add" Height="30" Margin="5, 0"/>
</StackPanel>
<ListBox Name="lstTodo" ItemsSource="{Binding}" BorderThickness="0" Padding="0" ItemTemplate="{StaticResource TodoTemplate}" ScrollViewer.HorizontalScrollBarVisibility="Disabled" HorizontalAlignment="Stretch">
</ListBox>
</StackPanel>
</ScrollViewer>
