如何根據UserControl更改WPF中的高度窗口？

我有兩個「UserControl」，每個UserControl都有不同的高度。我把這個UserControl放在同一個窗口中，但是在不同的時間，問題是如何根據高度UserControl動態改變高度窗口。如何根據UserControl更改WPF中的高度窗口？

首先用戶控件是：

<UserControl x:Class="UserControl1" 
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
      Height="auto" Width="auto"> 
<Grid Height="auto" Width="360" ..... > 
    <Grid VerticalAlignment="Center" > 
       <Grid.RowDefinitions> 
        <RowDefinition Height="Auto"/> 
        <RowDefinition Height="Auto" MinHeight="20.8"/> 
        <RowDefinition Height="Auto" MinHeight="20"/> 
        <RowDefinition Height="Auto" MinHeight="18.4"/> 
        <RowDefinition Height="Auto"/> 
        <RowDefinition Height="Auto" MinHeight="20.8"/> 
        <RowDefinition Height="Auto"/> 
        <RowDefinition Height="Auto"/> 
        <RowDefinition Height="Auto"/> 
        <RowDefinition Height="Auto"/> 
        <RowDefinition Height="Auto"/> 
        <RowDefinition Height="Auto"/> 
        <RowDefinition Height="Auto"/> 
        <RowDefinition Height="Auto"/> 
        <RowDefinition Height="Auto"/> 
        <RowDefinition Height="Auto"/> 
        <RowDefinition/> 
        <RowDefinition Height="Auto"/> 
        <RowDefinition Height="Auto"/> 
       </Grid.RowDefinitions> 
       <Grid.ColumnDefinitions> 
        <ColumnDefinition Width="33*"/> 
        <ColumnDefinition Width="17*"/> 
       </Grid.ColumnDefinitions> 
       <TextBlock Text="xx" Grid.Column="1" Grid.Row="0" ......./> 
       <TextBlock Text="yyy" Grid.Column="1" Grid.Row="1" ...... /> 
               ............ 
               ............ 
    </Grid> 
</Grid> 
</UserControl>

謝勝利用戶控件是：

<UserControl x:Class="UserControl2" 
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
      Height="auto" Width="auto"> 
<Grid Height="auto" Width="360" ..... > 
    <Grid VerticalAlignment="Center" > 
       <Grid.RowDefinitions> 
        <RowDefinition Height="Auto"/> 
        <RowDefinition Height="Auto"/> 
        <RowDefinition Height="Auto"/> 
       </Grid.RowDefinitions> 
       <Grid.ColumnDefinitions> 
        <ColumnDefinition Width="33*"/> 
        <ColumnDefinition Width="17*"/> 
       </Grid.ColumnDefinitions> 
       <TextBlock Text="xx" Grid.Column="1" Grid.Row="0" ......./> 
       <TextBlock Text="yyy" Grid.Column="1" Grid.Row="1" /> 
               ............ 
    </Grid> 
</Grid> 
</UserControl>

主窗口：

<Window 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     x:Class="MainWindow" 
     Title="Home" Height="550"*** Width="700" WindowStartupLocation="CenterScreen" ....> 
<Grid Name="Move"> 
    <Button Content="xxx" Height="28" TextBlock.FontSize="15" Name="btn1" Click="click1"/> 
    <Button Content="yyy" Grid.Row="1" Name="btn2" Click="click2"/> 
</Grid> 
</Window>

在代碼主窗口背後：

private void click1(object sender, RoutedEventArgs e) 
     { 
      UserControl1 add = new UserControl1(); 
      Move.Children.Clear(); 
      Move.Children.Add(add); 
     } 

     private void click2(object sender, RoutedEventArgs e) 
     { 
      UserControl2 add = new UserControl2(); 
      Move.Children.Clear(); 
      Move.Children.Add(add); 
     }

你可以嘗試在代碼後面做類似於：Application.Current.MainWindow.Height = add.Height; 你有沒有嘗試在主窗口把高度自動？ – sexta13

謝謝你幫助我，你能寫出答案 – ITInWorld

你可以嘗試在代碼後面做一些事情：Application.Current.MainWindow.Height = add.Height;你有沒有嘗試在主窗口把高度自動？

問候，
