How to remove Windows border from WPF UserControl?
提问by Tevis
To preface this question, I am working on coding the back end of an application whose UI was put together by someone else (I believe using Blend). The application consists of a series of "Screens," whose root element in XAML is "UserControl". There is no use of the "Window" tag anywhere in the source.
作为这个问题的序言，我正在编写一个应用程序的后端，该应用程序的 UI 是由其他人组装的（我相信使用 Blend）。该应用程序由一系列“屏幕”组成，其 XAML 中的根元素是“UserControl”。源代码中的任何地方都没有使用“Window”标签。
What I want to do is remove the Windows border that is added to the outside edge of the application when I run the program. The border currently consists of forward/backward buttons like a web browser, and an X button to close.
我想要做的是删除运行程序时添加到应用程序外边缘的 Windows 边框。边框当前由向前/向后按钮（如 Web 浏览器）和用于关闭的 X 按钮组成。
All I can find from searches are instructions to add
我能从搜索中找到的只是添加说明
WindowStyle="None"
to the
到
<Window>
element. But of course, I don't have one of those, and WindowStyle is not a property of UserControl. Anyone know how to accomplish this with UserControl root elements?
元素。但当然，我没有其中之一，而且 WindowStyle 不是 UserControl 的属性。任何人都知道如何使用 UserControl 根元素完成此操作？
Edit:The StartupUri for the application is
编辑：应用程序的 StartupUri 是
this.StartupUri = new Uri(@"pack://application:,,,/WpfPrototype1.Screens;Component/Screen_1.xaml");
the file it points to does not have a Window tag.
它指向的文件没有 Window 标签。

Based on the comments above it seems your MainWindowis created dynamically somewhere, however you can use the Applicationclass to get the applications MainWindow.
根据上面的评论，您似乎MainWindow是在某处动态创建的，但是您可以使用Application该类来获取应用程序MainWindow。
var mainWindow = Application.Current.MainWindow;
And you can then set your border style from there
然后你可以从那里设置你的边框样式
Example:
例子：
private void RemoveBorder()
{
var mainWindow = Application.Current.MainWindow;
if (mainWindow != null)//should never be
{
mainWindow.WindowStyle = System.Windows.WindowStyle.None; // removes top bar (icon, title, close buttons etc)
mainWindow.AllowsTransparency = true; //removes the border around the outside
}
}
