C# 在调整窗口大小时，如何在StackPanel中放置滑块以增加其大小？

我目前正在使用WPF在C#中设置一个应用程序，并希望有一个包含几个按钮和滑块的水平StackPanel。调整窗口大小时，按钮不应更改其大小，而是滑块应填满空间：

在我的当前代码中，滑块没有宽度。它很薄。我试着用镶板的装订来确定宽度。我将滑块放入StackPanel的原因是，滑块本身不使用按钮旁边的其余大小。我的XAML代码如下所示：

<StackPanel Name="controlPanel"  Grid.Row="1" Grid.ColumnSpan="2" Orientation="Horizontal">
     <StackPanel Name="buttonPanel" Orientation="Horizontal">
           <Button x:Name="btnTlPl" Content="PL" Height="25" Width="25" BorderBrush="Green" BorderThickness="2" Margin="1"/>
           <Button x:Name="btnTlSt" Content="ST" Height="25" Width="25" BorderBrush="Red" BorderThickness="2" Margin="1"/>
           <Button x:Name="btnTlFw" Content="FW" Height="25" Width="25" BorderBrush="LightSalmon" BorderThickness="2" Margin="1"/>
           <Button x:Name="btnTlBw" Content="BW" Height="25" Width="25" BorderBrush="LightSalmon" BorderThickness="2" Margin="1"/>
     </StackPanel>
     <StackPanel Name="sliderPanel" Orientation="Horizontal">
           <Slider x:Name="sliderTopLeft" Margin="0,0,0,0" 
               Background="AliceBlue" Width="{Binding Path=ActualWidth, ElementName=sliderPanel}" Orientation="Horizontal" HorizontalAlignment="Right" 
               Value="0" Minimum="0" Maximum="19" 
               SmallChange="1" LargeChange="1"
               TickPlacement="BottomRight" TickFrequency="1" IsSnapToTickEnabled="True" ValueChanged="sliderTopLeft_ValueChanged"/>
     </StackPanel>
</StackPanel>

对我有什么建议吗？

A

DockPanel

效果很好。还要确保删除

滑块上的
HorizontalAlignment=“Right”

<DockPanel
    Name="controlPanel"
    Grid.Row="1"
    Grid.ColumnSpan="2"
    LastChildFill="True">
    <StackPanel
        Name="buttonPanel"
        DockPanel.Dock="Left"
        Orientation="Horizontal">
        <Button x:Name="btnTlPl"
            Width="25"
            Height="25"
            Margin="1"
            BorderBrush="Green"
            BorderThickness="2"
            Content="PL" />
        <Button x:Name="btnTlSt"
            Width="25"
            Height="25"
            Margin="1"
            BorderBrush="Red"
            BorderThickness="2"
            Content="ST" />
        <Button x:Name="btnTlFw"
            Width="25"
            Height="25"
            Margin="1"
            BorderBrush="LightSalmon"
            BorderThickness="2"
            Content="FW" />
        <Button x:Name="btnTlBw"
            Width="25"
            Height="25"
            Margin="1"
            BorderBrush="LightSalmon"
            BorderThickness="2"
            Content="BW" />
    </StackPanel>
    <Slider x:Name="sliderTopLeft"
        Margin="0,0,0,0"
        Background="AliceBlue"
        DockPanel.Dock="Left"
        IsSnapToTickEnabled="True"
        LargeChange="1"
        Maximum="19"
        Minimum="0"
        Orientation="Horizontal"
        SmallChange="1"
        TickFrequency="1"
        TickPlacement="BottomRight"
        Value="0" />
</DockPanel>


如果网格有5列，前4列的宽度=自动，那该怎么办？
