wpf - 子控件的宽度应与父容器的宽度匹配

Question

我对 WPF 很陌生。我经常发现自己在努力让一堆子控件组合宽度以匹配给定的父容器。如下所示:

<ListBox x:Name="BrugereListBox" Grid.Column="0" Grid.Row="3" DataContext="{DynamicResource Brugere}" 
             ItemsSource="{Binding}" 
             PreviewMouseLeftButtonDown="BrugereListBox_MouseLeftButtonDown"
             PreviewMouseMove="BrugereListBox_PreviewMouseMove"
             >
        <ListBox.ItemTemplate  >
            <DataTemplate >
                <Border BorderBrush="Black" BorderThickness="1" Margin="2">
                    <StackPanel Orientation="Vertical" IsEnabled="True" 
                                PreviewMouseLeftButtonDown="StackPanel_PreviewMouseLeftButtonDown">
                        <StackPanel Orientation="Horizontal" >
                            <Label>Navn</Label>
                            <TextBox Text="{Binding Name}"></TextBox>
                        </StackPanel>
                        <StackPanel Orientation="Horizontal">
                            <Label>Password</Label>
                            <TextBox Text="{Binding Password}"></TextBox>
                        </StackPanel>
                        <StackPanel Orientation="Horizontal">
                            <Label>Email</Label>
                            <TextBox Text="{Binding Email}"></TextBox>
                        </StackPanel>
                    </StackPanel>
                </Border>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>

在这种情况下，我有兴趣获取堆栈面板的子项的宽度:

<StackPanel Orientation="Horizontal" >
                        <Label>Navn</Label>
                        <TextBox Text="{Binding Name}"></TextBox>
                    </StackPanel>

以匹配的宽度

<ListBox x:Name="BrugereListBox"

像这样的场景有什么通用的解决方案吗？

Answer 1

原来是一个骗局:

wpf border control to span the width of listboxItem

以及那里给出的答案:

This is probably more to do with the ListBoxItems themselves not taking up the full width of the ListBox. Add the HorizontalContentAlignment="Stretch" attribute to your ListBox and see if it stretches the individual items to fill the width.

所以改为:

<ListBox x:Name="BrugereListBox" Grid.Column="0" Grid.Row="3" DataContext="{DynamicResource Brugere}" 
             ItemsSource="{Binding}" 
             PreviewMouseLeftButtonDown="BrugereListBox_MouseLeftButtonDown"
             PreviewMouseMove="BrugereListBox_PreviewMouseMove"
             HorizontalContentAlignment="Stretch"
             >

但正如 Kent 所说，在我看来，使用 Grid 会更好。
