Wpf Dock Panel Dock左侧和Dock右侧

Question

我无法将停靠栏面板内的按钮向右移动，我尝试了几个解决方案，毕竟我把它们放在堆叠面板中并试图将它们移到右边，但是它们不会移动到任何地方，这里是它的外观：

这是我的代码：

   <GroupStyle>
            <GroupStyle.ContainerStyle>
                <Style TargetType="{x:Type GroupItem}">
                    <Setter Property="Template">
                        <Setter.Value>
                            <ControlTemplate TargetType="{x:Type GroupItem}">
                                <Expander IsExpanded="True"  Background="Black" Opacity="0.7">
                                    <Expander.Header>
                                        <DockPanel Height="50">
                                          <StackPanel Orientation="Horizontal" VerticalAlignment="Center" DockPanel.Dock="Right"> <Button DockPanel.Dock="Right" Content="Test" Margin="0,0,28,0"/></StackPanel>    
                                          <StackPanel Orientation="Horizontal" VerticalAlignment="Center" DockPanel.Dock="Left">  <TextBlock FontWeight="Normal" FontFamily="Verdana" FontSize="20" Height="25" Foreground="#83D744" Text="{Binding Path=Name,StringFormat= Order Number:# {0}}" /></StackPanel>
                                        </DockPanel>
                                    </Expander.Header>
                                    <Expander.Content>
                                        <ItemsPresenter />
                                    </Expander.Content>
                                </Expander>
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>
                </Style>
            </GroupStyle.ContainerStyle>
        </GroupStyle>
    </DataGrid.GroupStyle>

修改

上面这导致停靠面板上的宽度

<DockPanel Height="50" Width="{Binding ActualWidth, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=DataGrid}}">
                                        <Button DockPanel.Dock="Right" Content="Test" Margin="0,0,28,0"/>
                                        <TextBlock FontWeight="Normal" FontFamily="Verdana" FontSize="20" Height="25" Foreground="#83D744" Text="{Binding Path=Name,StringFormat= Order Number:# {0}}" />
                                    </DockPanel>

Answer 1

将Width="{Binding ActualWidth, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=DataGrid}}"应用到DockPanel，看看是否能解决您的问题。

Answer 2

尝试以下方法。这适用于我的项目

<DockPanel Height="50">
   <grid DockPanel.Dock="Right">
       <Button  Content="Test" Margin="0,0,28,0"/>
   </grid >    
   <grid DockPanel.Dock="Left">
       <TextBlock FontWeight="Normal" FontFamily="Verdana" FontSize="20" Height="25" Foreground="#83D744" Text="{Binding Path=Name,StringFormat= Order Number:# {0}}"/>
   </grid>
</DockPanel>
