不能見得到的佈局權（WPF）

Question

首先，這裏是我的XAML標記（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 Content="Alarm values" Style="{DynamicResource Label}"/> 
      <Label Content="Period:" Style="{DynamicResource Label}"/> 
      <Label Content="Min Pv:" Style="{DynamicResource Label}"/> 
      <Label Content="Max Pv:" Style="{DynamicResource Label}"/> 
      <Label Style="{DynamicResource Label}"/> 
      <Label Content="Local setpoint" Style="{DynamicResource Label}"/>

      <Label Content="External setpoint" Style="{DynamicResource Label}"/> 
      <Label Content="Sp addition:" Style="{DynamicResource Label}"/> 
      <Label Content="Default manual setpoint:" Style="{DynamicResource Label}"/> 
      <Label 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的窗口（加載網頁上面）：

<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"> 

樣式：

<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> 
     <Setter Property="Label.Padding" Value="0"/> 
    </Style> 
    <Style x:Key="Label"> 
     <Setter Property="Label.Height" Value="20"/> 
     <Setter Property="Panel.Margin" Value="0,0,25,0"/> 
     <Setter Property="Label.Padding" Value="0"/> 
    </Style> 
    <Style x:Key="Form"> 
     <Setter Property="Page.Background" Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}"/> 
    </Style> 
</Application.Resources> 

我是新來的WPF，它可能顯示。我無法讓滾動條像我想要的那樣工作。出於某種原因，垂直滾動條從未出現，即使我的窗口高度小於上面顯示的其XAML標記頁面的最小高度。

我是新來的所有這些，所以如果任何人都可以給我一些建議，我做錯了什麼或發佈有用的鏈接到有用的資源，我會很感激。

Answer 1

顯然我通過從頁面中刪除MinHeight解決了它。我仍然不明白這些屬性（MinHeight/MinWidth）的重點，因爲窗口不尊重它們，並且如果添加了滾動條，它將被完全禁用。

Answer 2

你可以使用一個網格佈局，而不是

<Grid> 
    <Grid.ColumnDefinitions> 
     <ColumnDefinition Width="Auto"/> 
     <ColumnDefinition Width="*"/> 
     <ColumnDefinition Width="Auto"/> 
    </Grid.ColumnDefinitions> 
    <StackPanel Grid.Column="0"/> 
    <StackPanel Grid.Column="1"/> 
    <StackPanel Grid.Column="2"/> 
</Grid> 

第一和第三列將佔據儘可能多的空間可以根據需要，第二個會佔用休息。

至於Scrollbars：這實際上應該可以工作，你可以爲你的Frame添加XAML嗎？
