Window 打开时文本消失

Question

所以，我有一个注册表格，在设计中，它看起来像这样：

这里是 XAML：

<Rectangle x:Name="signInBox" Fill="#FF5F5F6E" HorizontalAlignment="Center" Height="450" Margin="0,0,0,0" Stroke="Black" VerticalAlignment="Center" Width="640" StrokeThickness="3" Visibility="Visible"/>
<TextBlock x:Name="signUpText" HorizontalAlignment="Center" Margin="0,-350,0,0" TextWrapping="Wrap" Text="Sign up for Horizon Chat" VerticalAlignment="Center" FontFamily="Muli" FontSize="36" Foreground="White"/>
<!-- For the username box -->
<TextBox x:Name="nameSignUpBox" HorizontalAlignment="Center" Margin="0,-150,0,0" TextWrapping="Wrap" VerticalAlignment="Center" Width="370" FontFamily="Muli" FontSize="26" BorderThickness="2" MaxHeight="61" MaxWidth="686"/>
<TextBlock x:Name="nameSignUpBoxDescription" HorizontalAlignment="Center" Margin="456,334,738,544" TextWrapping="Wrap" Text="Username" VerticalAlignment="Center" FontFamily="Muli" FontSize="18" Foreground="#FFDADADA"/>
<!-- For the email box -->
<TextBox x:Name="emailSignUpBox" HorizontalAlignment="Center" Margin="0,0,0,0" TextWrapping="Wrap" VerticalAlignment="Center" Width="370" FontFamily="Muli" FontSize="26" BorderThickness="2" MaxHeight="61" MaxWidth="686"/>
<TextBlock x:Name="emailSignUpBoxDescription" HorizontalAlignment="Center" Margin="456,408,778,468" TextWrapping="Wrap" Text="Email" VerticalAlignment="Center" FontFamily="Muli" FontSize="18" Foreground="#FFDADADA"/>
<!-- For the password box -->
<PasswordBox x:Name="passwordSignUpBox" HorizontalAlignment="Center" Margin="0,150,0,0" VerticalAlignment="Center" Width="370" FontFamily="Muli" FontSize="26" BorderThickness="2" MaxHeight="61" MaxWidth="686"/>
<TextBlock x:Name="passwordSignUpBoxDescription" HorizontalAlignment="Center" Margin="455,484,742,393" TextWrapping="Wrap" Text="Password" VerticalAlignment="Center" FontFamily="Muli" FontSize="18" Foreground="#FFDADADA"/>

然后，当程序启动时，它会进行一些更改，例如更改 window 大小以适合该框，并使其可见，等等。这是相关代码：

BrushConverter brushconverter = new BrushConverter();
this.Background = (Brush)brushconverter.ConvertFrom("#FF9C9C9C");
this.Width = 640;
this.Height = 450;
this.ResizeMode = ResizeMode.NoResize;
double screenWidth = System.Windows.SystemParameters.PrimaryScreenWidth;
double screenHeight = System.Windows.SystemParameters.PrimaryScreenHeight;
double windowWidth = this.Width;
double windowHeight = this.Height;
this.Left = (screenWidth / 2) - (windowWidth / 2);
this.Top = (screenHeight / 2) - (windowHeight / 2);

现在，所有这些都与 window 有关，因为在我的情况下，我已经拥有所有可见的东西。因此，当我启动该程序时，除了框上方的小文本（用户名、电子邮件和密码），我得到了所有内容 。这是：

现在，我的猜测是它在调整大小时将文本移动到某处，因为当我不调整 window 大小时，它仍然存在（就像在设计器中一样）。但是，如果它将我的文本移动到不同的地方，这仍然是一个问题。我该如何解决这个问题？

编辑： 我尝试调整设计器的大小 window，这是调整大小大约 100px 的前后：

之前：

50%:

我使用 @shadow32 将控件重新组织到一个视图框中，并为您的动态调整大小要求创建了一个纯粹的 xaml 解决方案。
我也清理了XAML，少即是多呵呵。
希望您可以使用这种方法，尽可能在设计器中保留布局。
它提供了一个更易于维护的解决方案。
