wpf - WPF:在最右边的StackPanel/DockPanel中对齐最后两个控件

到目前为止，那是我的代码不起作用：

   <DockPanel  >
            <Button Content="Start" Command="{Binding Path=FirstDateCommand}" />
            <Button Content="Back"  Command="{Binding Path=PreviousDateCommand}" />
            <DatePicker Width="150"
                SelectedDate="{Binding Path=SelectedDate}"
                DisplayDateStart="{Binding Path=MinDate}"
                DisplayDateEnd="{Binding Path=MaxDate}" SelectedDateFormat="Long" />
            <Button Content="Forward" Command="{Binding Path=NextDateCommand}" />
            <Button Content="End"     Command="{Binding Path=LastDateCommand}" />

            <Button Command="{Binding PrintCommand}" Content="Print Planner" />
            <Button Command="{Binding ToggleDocumentsCommand}" Content="Show Docs"  />
            <Button Command="{Binding MaterialExplorerShowCommand}" Content="Browse Docs" />
            <Button Command="{Binding LessonPlannerCommand}" Content="Edit Planner" />
            <TextBox Text="{Binding SearchText,Mode=TwoWay}" Width="50" />
            <Button Command="{Binding FindAllCommand}" Content="Search"  />

            <DockPanel DockPanel.Dock="Right" HorizontalAlignment="Right">
                <TextBlock Text="class code:" VerticalAlignment="Center" />
                <ComboBox
                ItemsSource="{Binding GroupViewModelList}"
                Style="{StaticResource GroupViewModelStyle}"
                ItemTemplate="{StaticResource GroupViewModelItemTemplate}"
                Width="100"/>
            </DockPanel>

        </DockPanel>

如何在最右边的图像上设置最后2个控件？

更新：

<Grid  Name="MainGrid">
        <Grid.RowDefinitions>
            <RowDefinition Height="40" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*" />
        </Grid.ColumnDefinitions>
        <Grid Margin="10,10,10,0"  Grid.Row="0" Name="ButtonBar">
            <StackPanel FocusManager.IsFocusScope="True" Orientation="Horizontal">
                <ComboBox
                        AlternationCount="2"
                        FontSize="16"
                        VerticalContentAlignment="Center"
                        Width="100"
                        ItemContainerStyle="{StaticResource alternateColor}"
                        ItemsSource="{Binding Source={x:Static Member=Fonts.SystemFontFamilies}}" x:Name="fontComboFast">
                    <ComboBox.ItemsPanel>
                        <ItemsPanelTemplate>
                            <VirtualizingStackPanel VirtualizingStackPanel.VirtualizationMode="Recycling" />
                        </ItemsPanelTemplate>
                    </ComboBox.ItemsPanel>
                    <ComboBox.ItemTemplate>
                        <DataTemplate>
                            <TextBlock Width="100" Text="{Binding}" FontFamily="{Binding }" />
                        </DataTemplate>
                    </ComboBox.ItemTemplate>
                </ComboBox>

                <!--<View:FormatButtonBar />-->
                <View:DateNavigatorView />
                <View:LessonPlannerView />
                <!--<View:TextFormatBarUC />-->
            </StackPanel>
        </Grid>

这两个控件位于LessonPlannerView（UserControl）中

在LessonPlannerView内部，您可以找到以下代码：

...
    <Grid >
        <DockPanel>
            <Button Command="{Binding PrintCommand}" Content="Print Planner" />
            <Button Command="{Binding ToggleDocumentsCommand}" Content="Show Docs"  />
            <Button Command="{Binding MaterialExplorerShowCommand}" Content="Browse Docs" />
            <Button Command="{Binding LessonPlannerCommand}" Content="Edit Planner" />
            <TextBox Text="{Binding SearchText,Mode=TwoWay}" Width="50" />
            <Button Command="{Binding FindAllCommand}" Content="Search"  />
            <StackPanel x:Name="ClassCodeChooser" Orientation="Horizontal" DockPanel.Dock="Right" HorizontalAlignment="Right">
                <TextBlock Text="class code:" VerticalAlignment="Center" />
                <ComboBox ItemsSource="{Binding SchoolclassCodeList}"
                />
        </StackPanel>
        </DockPanel>
    </Grid>
</UserControl>

最佳答案

那应该没问题，但您实际上不需要嵌套的DockPanel。您可以将内部DockPanel更改为水平StackPanel。

但是真正的问题是，外部DockPanel似乎并没有扩展到其容器的整个宽度。在外部DockPanel上设置一个Background，以直观地指示为什么它没有填充容器。

针对下面的评论主题，添加以下示例

<Grid Name="ButtonBar">
    <Grid.RowDefinitions>
        <RowDefinition Height="40" />
        <RowDefinition Height="*" />
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />
    </Grid.ColumnDefinitions>

    <DockPanel Grid.Row="0">
        <View:FormatButtonBar />  <!-- this will dock left -->
        <View:DateNavigatorView />  <!-- this will dock left -->
        <View:LessonPlannerView />  <!-- this will dock left -->
        <View:TextFormatBarUC /> <!-- this will fill -->
    </DockPanel>

</Grid>
