爲什麼我看不到我創建的菜單？

Question

所以我創建了一個小的wpf應用程序來獲得樂趣，我希望它有一個菜單。我創建了菜單，但沒有，但是當我運行程序時，菜單根本沒有顯示出來。在菜單的代碼是目前：

<Window x:Class="TBA_Alpha.MainWindow" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    Title="TBA LogIn" Height="350" Width="525"> 
<Grid> 
    <PasswordBox x:Name="tbPsw" HorizontalAlignment="Left" Margin="214,143,0,0" VerticalAlignment="Top" Width="133" SelectionBrush="Black" Background="White"> 
     <PasswordBox.BorderBrush> 
      <LinearGradientBrush EndPoint="0,20" MappingMode="Absolute" StartPoint="0,0"> 
       <GradientStop Color="#FFABADB3" Offset="0.05"/> 
       <GradientStop Color="#FFE2E3EA" Offset="0.07"/> 
       <GradientStop Color="Black" Offset="1"/> 
      </LinearGradientBrush> 
     </PasswordBox.BorderBrush> 
    </PasswordBox> 
    <TextBox x:Name="tbUId" HorizontalAlignment="Left" Height="23" Margin="214,94,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="133" SelectionBrush="Black"> 
     <TextBox.Background> 
      <SolidColorBrush Color="White"/> 
     </TextBox.Background> 
     <TextBox.BorderBrush> 
      <LinearGradientBrush EndPoint="0,20" MappingMode="Absolute" StartPoint="0,0"> 
       <GradientStop Color="#FFABADB3" Offset="0.05"/> 
       <GradientStop Color="#FFE2E3EA" Offset="0.07"/> 
       <GradientStop Color="Black" Offset="1"/> 
      </LinearGradientBrush> 
     </TextBox.BorderBrush> 
    </TextBox> 
    <Button Content="LogIn" HorizontalAlignment="Left" Margin="239,200,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click"/> 
    <TextBlock HorizontalAlignment="Left" Margin="214,73,0,0" TextWrapping="Wrap" Text="Your UserID:" VerticalAlignment="Top"/> 
    <TextBlock HorizontalAlignment="Left" Margin="214,122,0,0" TextWrapping="Wrap" Text="Your Password:" VerticalAlignment="Top"/> 
    <Menu HorizontalAlignment="Left" Height="25" VerticalAlignment="Top" Width="43" BorderThickness="1"> 
     <MenuItem Header=" New " RenderTransformOrigin="0.5,0.5" Width="63" Height="36" Background="White" Visibility="Visible" AllowDrop="True" IsHitTestVisible="True"> 
      <MenuItem Header=" User " Click="newUser"/> 
     </MenuItem> 
    </Menu> 
</Grid> 

任何任何幫助將大大讚賞的感謝。

編輯：增加了整個XAML代碼爲WPF，這裏的菜單靠近代碼的結束

編輯：刪除所有的額外的東西，只留下頭，仍然遇到了同樣的問題

後

編輯：嘗試的代碼在不同的清潔項目和它的工作，謝謝，你

的問題是，大部分的控件的使用Magrin屬性本身分開，而不是Grid的功能。由於他們都沒有指定附加屬性Grid.Row，它們都在同一行。由於Menu未指定Margin，因此它位於Grid的頂部，因此與其他控件重疊。

使用try實際電網行

<Grid> 
    <Grid.RowDefinitions> 
     <RowDefinition/> 
     <RowDefinition/> 
     <RowDefinition/> 
     <RowDefinition/> 
     <RowDefinition/> 
     <RowDefinition/> 
    </Grid.RowDefinitions> 

    <PasswordBox x:Name="tbPsw" HorizontalAlignment="Left" Grid.Row="0" VerticalAlignment="Top" Width="133" SelectionBrush="Black" Background="White"> 
     <PasswordBox.BorderBrush> 
      <LinearGradientBrush EndPoint="0,20" MappingMode="Absolute" StartPoint="0,0"> 
       <GradientStop Color="#FFABADB3" Offset="0.05"/> 
       <GradientStop Color="#FFE2E3EA" Offset="0.07"/> 
       <GradientStop Color="Black" Offset="1"/> 
      </LinearGradientBrush> 
     </PasswordBox.BorderBrush> 
    </PasswordBox> 
    <TextBox x:Name="tbUId" HorizontalAlignment="Left" Height="23" Grid.Row="1" TextWrapping="Wrap" VerticalAlignment="Top" Width="133" SelectionBrush="Black"> 
     <TextBox.Background> 
      <SolidColorBrush Color="White"/> 
     </TextBox.Background> 
     <TextBox.BorderBrush> 
      <LinearGradientBrush EndPoint="0,20" MappingMode="Absolute" StartPoint="0,0"> 
       <GradientStop Color="#FFABADB3" Offset="0.05"/> 
       <GradientStop Color="#FFE2E3EA" Offset="0.07"/> 
       <GradientStop Color="Black" Offset="1"/> 
      </LinearGradientBrush> 
     </TextBox.BorderBrush> 
    </TextBox> 
    <Button Content="LogIn" HorizontalAlignment="Left" Grid.Row="2" VerticalAlignment="Top" Width="75" Click="Button_Click"/> 
    <TextBlock HorizontalAlignment="Left" Grid.Row="3" TextWrapping="Wrap" Text="Your UserID:" VerticalAlignment="Top"/> 
    <TextBlock HorizontalAlignment="Left" Grid.Row="4" TextWrapping="Wrap" Text="Your Password:" VerticalAlignment="Top"/> 
    <Menu Grid.Row="5" HorizontalAlignment="Left" Height="25" VerticalAlignment="Top" Width="43" BorderThickness="1"> 
     <MenuItem Header=" New " RenderTransformOrigin="0.5,0.5" Width="63" Height="36" Background="White" Visibility="Visible" AllowDrop="True" IsHitTestVisible="True"> 
      <MenuItem Header=" User " Click="newUser"/> 
     </MenuItem> 
    </Menu> 
</Grid>
