我对WPF很陌生。我只是尝试使用网格和列表框进行一些布局,但我有一些填充/间距/边距/边框(只是称之为边框为了短)我无法逃脱。
边界围绕四个元素,元素本身没有问题它们之间没有空间。
还尝试了WPF检查器,但我找不到这是从哪里来的。没什么可看的。
这是我的 XAML:
<Window x:Class="WpfElements.FourElements"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="FourElements" Height="701" Width="351">
<Grid Background="Red" Margin="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<ListBox Margin="0" BorderThickness="0" Padding="0" Grid.Row="0" Grid.Column="0" Background="Lime" SelectionMode="Single" ItemsSource="{Binding Path=Texts}" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Disabled" VerticalContentAlignment="Stretch" HorizontalContentAlignment="Stretch">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="0">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
</Grid>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<TextBox Text="{Binding ItemText}" Grid.Row="{Binding Path=Row}" Grid.Column="{Binding Path=Col}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="0"></TextBox>
</DataTemplate>
</ListBox.ItemTemplate>
<ListBox.ItemContainerStyle>
<Style>
<Setter Property="Grid.Column" Value="{Binding Path=Col}"/>
<Setter Property="Grid.Row" Value="{Binding Path=Row}"/>
<Setter Property="ContentControl.HorizontalContentAlignment" Value="Stretch"/>
<Setter Property="ContentControl.VerticalContentAlignment" Value="Stretch"/>
<Setter Property="ContentControl.Margin" Value="0"/>
<Setter Property="ContentControl.Padding" Value="0"/>
<Setter Property="Control.BorderThickness" Value="0"/>
</Style>
</ListBox.ItemContainerStyle>
</ListBox>
</Grid>
希望有人能帮助我摆脱这个边界。非常感谢!
问题是ListBox
Template
内部的第一个Border
,它Padding
设置为1,1,1,1
。
看起来像这样
<Style TargetType="{x:Type ListBox}" ...>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBox}">
<Border x:Name="Bd"
Padding="1">
<!-- ... -->
正如你在Template
中看到的,Border
的名字是Bd。
更改ListBox
的Template
或在Loaded
事件中将其设置为 0
哈姆勒
<ListBox ...
Loaded="ListBox_Loaded">
代码隐藏
private void ListBox_Loaded(object sender, RoutedEventArgs e)
{
ListBox listBox = sender as ListBox;
Border Bd = listBox.Template.FindName("Bd", listBox) as Border;
Bd.Padding = new Thickness(0);
}
您是否尝试过为 ListBox 或网格设置控件模板。您应该能够通过编写自己的模板来摆脱边框。
