如何让UserControl伸展以填充分配的空间?

在630 x 400窗口中,我正在加载XAML元素:

    顶部的
  • 菜单
  • 动态用户控制
  • 底部的页脚

问题在于,当我设置UserControl的背景时,颜色只会下降到内容。我希望UserControl的背景当然涵盖整个UserControl。我试过了:

    用户控件 中的 VerticalContentAlignment =“拉伸” 用户控件 中的 VerticalAlignment =“拉伸” MainView 中的 VerticalContentAlignment =“拉伸” 在 MainView
  • VerticalAlignment =“拉伸”

但颜色仍然拒绝下降。我不想设置固定宽度,因为用户可以增加应用程序的大小。

如何获取UserControl的背景颜色以填充UserControl的整个区域而不仅仅是其内容的区域?

PageItemOptionsView.xaml:

<UserControl x:Class="TestMenu234.Views.PageItemOptionsView"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             VerticalContentAlignment="Stretch"
             VerticalAlignment="Stretch"
             Background="#ddd">
    <StackPanel Margin="10">
        <TextBlock Text="This is the options area."/>
        <Button Content="Click to go to the Manage Customers page."
                    Width="200"/>
    </StackPanel>
</UserControl>

MainView.xaml:

<Window x:Class="TestMenu234.Views.MainView"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:c="clr-namespace:TestMenu234.Commands"
    xmlns:vm="clr-namespace:TestMenu234.ViewModels"
    xmlns:v="clr-namespace:TestMenu234.Views"
    Title="Main Window" Height="400" Width="630" MinWidth="630">

    <DockPanel LastChildFill="False">

        <Menu DockPanel.Dock="Top">
            <MenuItem 
                Header="Pages" ItemsSource="{Binding AllPageItemViewModels}"
                      ItemTemplate="{StaticResource CodeGenerationMenuTemplate}"/>
        </Menu>

        <ContentControl
            DockPanel.Dock="Top"
            VerticalAlignment="Stretch"
            VerticalContentAlignment="Stretch"
            Content="{Binding CurrentPageItemViewModel}"/>

        <Border DockPanel.Dock="Bottom" Padding="5 5 5 0" Background="#eee">
            <Grid Background="#eee">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*" MinWidth="300"/>
                    <ColumnDefinition Width="200"/>
                    <ColumnDefinition Width="100"/>
                </Grid.ColumnDefinitions>
                <Slider 
                Grid.Column="0"
                HorizontalAlignment="Left"
                Value="{Binding CurrentPageItemViewModelIndex}"
                Width="300"
                Minimum="0"
                Maximum="{Binding HighestPageItemIndex}"/>

                <TextBlock Grid.Column="1" 
                           HorizontalAlignment="Center" FontWeight="Bold" 
                           Text="{Binding CurrentPageItemViewModelTitle}"/>

                <DockPanel Grid.Column="2" Margin="0 0 0 5" LastChildFill="False">
                    <Button
                    Margin="3 0 0 0"
                    DockPanel.Dock="Right"
                HorizontalAlignment="Right"
                Content="Next" Command="{Binding NextPageCommand}"/>
                    <Button
                    DockPanel.Dock="Right"
                Content="Prev" Command="{Binding PreviousPageCommand}"/>
                </DockPanel>
            </Grid>
        </Border>

    </DockPanel>
</Window>

你试过......

  1. 设置保证金=“0”
  2. 使用LastChildFill =“True”
  3. 使您的控件成为DockPanel的最后一个子节点
