Wpf 项目宽度在控件宽度之后的列表框

我正在构建一个WPF用户控件，其中包含一个列表，其中的项目显示为图标和文本。但是，文本有不同的长度，我希望它们水平滚动。相反，我希望这些项目与用户控件具有相同的宽度，并且文本被包装显示（因此具有垂直滚动）

这是我的XAML

<UserControl x:Class="Demo.NotificationsWidget"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
   <Border CornerRadius="2" 
           BorderThickness="1" BorderBrush="LightGray"
           Background="White">
      <DockPanel LastChildFill="True">
         <TextBlock Text="Alerts" DockPanel.Dock="Top" Margin="5" FontSize="15"/>

         <ListBox Name="alertsList" DockPanel.Dock="Bottom" Margin="5"
               Grid.IsSharedSizeScope="True"
               HorizontalContentAlignment="Stretch"
               BorderThickness="0" 
               ItemsSource="{Binding}">
            <ListBox.ItemTemplate>
               <DataTemplate>
                  <Border BorderThickness="0,1,0,0" BorderBrush="Gray" Margin="5,0,5,5">
                     <Grid>
                        <Grid.ColumnDefinitions>
                           <ColumnDefinition SharedSizeGroup="col1" Width="40" />
                           <ColumnDefinition SharedSizeGroup="col2" Width="*" />
                        </Grid.ColumnDefinitions>

                        <Image Grid.Column="0" Source="{Binding Image}" Width="24" Height="24" Margin="5" />
                        <StackPanel Grid.Column="1" Orientation="Vertical" Margin="5">
                           <TextBlock Text="{Binding Title}" TextWrapping="Wrap" FontWeight="Bold" />
                           <TextBlock Text="{Binding Text}" TextWrapping="Wrap" />
                        </StackPanel>
                     </Grid>
                  </Border>
               </DataTemplate>
            </ListBox.ItemTemplate>
         </ListBox>
      </DockPanel>
   </Border>
</UserControl>

但是，当窗口调整大小时，列表及其项目会自动调整大小，这一点很重要。

在文本块上，请尝试：

Width="{Binding ElementName=alertsList, Path=ActualWidth}"> 

如果你需要脱掉一些，那么看看我对这个问题的回答

我通过用

DockPanel

替换

网格

，实现了预期的结果

        <ListBox.ItemTemplate>
           <DataTemplate>
              <Border BorderThickness="0,1,0,0" BorderBrush="Black" Margin="0,0,0,5">
                 <DockPanel LastChildFill="True">
                    <Image DockPanel.Dock="Left" Source="{Binding Image}" Width="24" Height="24" Margin="0,5,0,5"
                           VerticalAlignment="Top"/>

                    <StackPanel DockPanel.Dock="Right" Orientation="Vertical"
                                Margin="5,2,0,0"
                                VerticalAlignment="Top">
                       <TextBlock Text="{Binding Title}" TextWrapping="Wrap" FontWeight="Bold" />
                       <TextBlock Text="{Binding Text}" TextWrapping="Wrap" FontSize="12" Margin="0,2,0,0" />
                    </StackPanel>
                 </DockPanel>
              </Border>
           </DataTemplate>
        </ListBox.ItemTemplate>

        <ListBox.ItemTemplate>
           <DataTemplate>
              <Border BorderThickness="0,1,0,0" BorderBrush="Black" Margin="0,0,0,5">
                 <DockPanel LastChildFill="True">
                    <Image DockPanel.Dock="Left" Source="{Binding Image}" Width="24" Height="24" Margin="0,5,0,5"
                           VerticalAlignment="Top"/>

                    <StackPanel DockPanel.Dock="Right" Orientation="Vertical"
                                Margin="5,2,0,0"
                                VerticalAlignment="Top">
                       <TextBlock Text="{Binding Title}" TextWrapping="Wrap" FontWeight="Bold" />
                       <TextBlock Text="{Binding Text}" TextWrapping="Wrap" FontSize="12" Margin="0,2,0,0" />
                    </StackPanel>
                 </DockPanel>
              </Border>
           </DataTemplate>
        </ListBox.ItemTemplate>
