无法看到正确的布局(WPF)

首先，这里是我的XAML标记(ModifySpDefaultValues.xaml):

<Page x:Class="EMS_WPF_Test.ModifySpDefaultValues"
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
  xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
  xmlns:local="clr-namespace:EMS_WPF_Test"
  mc:Ignorable="d" d:DesignWidth="360" Title="ModifyPvDefaultValues" Style="{DynamicResource Form}" d:DesignHeight="360" MinHeight="360" MinWidth="360">
<ScrollViewer Margin="10" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto">
    <DockPanel>
        <StackPanel DockPanel.Dock="Left">
            <Label Content="Min/max" Style="{DynamicResource Label}"/>
            <Label Content="Minimum allowed sp:" Style="{DynamicResource Label}"/>
            <Label Content="Maximum allowed sp:" Style="{DynamicResource Label}"/>
            <Label Style="{DynamicResource Label}"/>

            <Label Style="{DynamicResource Label}"/>
            <Label Content="External setpoint" Style="{DynamicResource Label}"/>
            <Label Content="Sp addition:" Style="{DynamicResource Label}"/>

            <Label x:Name="GoBack" Content="Back" Style="{DynamicResource Hyperlink}" MouseLeftButtonUp="GoBack_MouseLeftButtonUp"/>
        </StackPanel>
        <StackPanel DockPanel.Dock="Right">
            <Label Style="{DynamicResource Label}"/>
            <Label Content="What's this?" Style="{DynamicResource Hyperlink}"/>
            <Label Content="What's this?" Style="{DynamicResource Hyperlink}"/>
            <Label Style="{DynamicResource Label}"/>
            <Label Style="{DynamicResource Label}"/>
            <Label Content="What's this?" Style="{DynamicResource Hyperlink}"/>
            <Label Content="What's this?" Style="{DynamicResource Hyperlink}"/>
            <Label Content="What's this?" Style="{DynamicResource Hyperlink}"/>
            <Label Style="{DynamicResource Label}"/>
            <Label Style="{DynamicResource Label}"/>
            <Label Content="What's this?" Style="{DynamicResource Hyperlink}"/>
            <Label Style="{DynamicResource Label}"/>
            <Label Style="{DynamicResource Label}"/>
            <Label Content="What's this?" Style="{DynamicResource Hyperlink}"/>
            <Label Content="What's this?" Style="{DynamicResource Hyperlink}"/>
        </StackPanel>
        <StackPanel>
            <Label Style="{DynamicResource Label}"/>
            <TextBox Style="{DynamicResource TextBox}"/>
            <TextBox Style="{DynamicResource TextBox}"/>
            <Label Style="{DynamicResource Label}"/>
            <Label Style="{DynamicResource Label}"/>
            <TextBox Style="{DynamicResource TextBox}"/>
            <TextBox Style="{DynamicResource TextBox}"/>
            <TextBox Style="{DynamicResource TextBox}"/>
            <Label Style="{DynamicResource Label}"/>
            <Label Style="{DynamicResource Label}"/>
            <TextBox Style="{DynamicResource TextBox}"/>
            <Label Style="{DynamicResource Label}"/>
            <Label Style="{DynamicResource Label}"/>
            <TextBox Style="{DynamicResource TextBox}"/>
            <TextBox Style="{DynamicResource TextBox}"/>
        </StackPanel>
    </DockPanel>
</ScrollViewer>

XAML for window(加载以上页面):

<NavigationWindow x:Class="EMS_WPF_Test.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:local="clr-namespace:EMS_WPF_Test"
    mc:Ignorable="d"
    Title="Modify device" MinHeight="300" MinWidth="680" Height="300" Width="680" Source="ModifySpDefaultValues.xaml" WindowStartupLocation="CenterScreen" ShowsNavigationUI="False">

样式:

<Application x:Class="Test.App"
 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 StartupUri="MainWindow.xaml">
<Application.Resources>
    <!-- Header text style -->
    <Style x:Key="Hyperlink">
        <Setter Property="Label.Margin" Value="0,0,25,0"></Setter>
        <Setter Property="Label.Foreground" Value="{DynamicResource {x:Static SystemColors.HotTrackBrushKey}}"></Setter>
        <Setter Property="Label.Cursor" Value="Hand"></Setter>
        <Setter Property="Label.Height" Value="20"></Setter>
        <Setter Property="Label.Padding" Value="0"/>
    </Style>
    <Style x:Key="OperationMethodBox">
        <Setter Property="Label.Margin" Value="0,0,25,0"></Setter>
        <Setter Property="ComboBox.Width" Value="300"></Setter>
        <Setter Property="Label.Height" Value="20"></Setter>
        <Setter Property="Label.Padding" Value="0"/>
    </Style>
    <Style x:Key="TextBox">
        <Setter Property="Label.Margin" Value="0,0,25,0"></Setter>
        <Setter Property="TextBox.MinWidth" Value="50"></Setter>
        <Setter Property="Label.Height" Value="20"></Setter>

    <Style x:Key="Label">

        <Setter Property="Label.Padding" Value="0"/>
    </Style>
    <Style x:Key="Form">

    </Style>
</Application.Resources>

我是WPF的新手，它可能会显示。我不能让滚动条像我想的那样工作。由于某些原因，即使我的窗口的高度小于上面展示的带有XAML标记的页面的最小高度，垂直滚动条也不会出现。

我对这一切都很陌生，所以如果有人能给我一些建议，告诉我做错了什么，或者发布有用的资源链接，我将不胜感激。
