How to create a WPF Window without a border that can be resized?
提问by jsirr13
Is there a way in WPF where I can remove the main window's border, yet allow that window to be resized (without grip)?
在 WPF 中有没有办法可以删除主窗口的边框，但允许调整该窗口的大小（没有抓地力）？
I realized there's a way to do this scenario by setting resize mode to CanResizeWithGrip. However, I want to be able to do it with the resize mode set to CanResize.
我意识到有一种方法可以通过将调整大小模式设置为CanResizeWithGrip. 但是，我希望能够将调整大小模式设置为CanResize.
I tried setting the following:
我尝试设置以下内容：
ResizeMode="CanResize"
WindowStyle="None"
AllowsTransparency="True"
However, by setting AllowsTransparency, it removes the ability to resize without the grip. Any ideas how I can pull this off?
但是，通过设置AllowsTransparency，它取消了在没有手柄的情况下调整大小的能力。有什么想法可以解决这个问题吗？
I also should note that I can't set AllowsTransparencyto true anyway, because I am using a winformshost control in my window, which is not shown when AllowsTransparencyis true.
我还应该注意，AllowsTransparency无论如何我都不能设置为 true，因为我在我的窗口中使用了一个 winformshost 控件，当它AllowsTransparency为 true时不会显示。

I know this is an old question, but I just wanted to put up a working sample for newcomers.

This can happen if ResizeBorderThicknessis set to 0.
如果ResizeBorderThickness设置为 0，就会发生这种情况。
It can be set to a positive value in XAML like this:
它可以在 XAML 中设置为正值，如下所示：
<WindowChrome>
<WindowChrome.ResizeBorderThickness>
<Thickness>1</Thickness>
</WindowChrome.ResizeBorderThickness>
</WindowChrome>

You can use the WPF customizable window library, available here: http://wpfwindow.codeplex.com/
您可以使用 WPF 可自定义的窗口库，可在此处获得：http: //wpfwindow.codeplex.com/
Then, when using the library's window type, you can set the same properties as you listed above
然后，当使用库的窗口类型时，您可以设置与上面列出的相同的属性
<CustomWindow:EssentialWindow x:Class="CustomWindowDemo.DemoEssentialWindow"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:CustomWindow="clr-namespace:CustomWindow;assembly=CustomWindow"
AllowsTransparency="True" ResizeMode="CanResize" WindowStyle="None" Title="EssentialWindow"
Height="300" Width="250">

The user needs something to interact with to resize the window. If you don't like the default border or grip, you'll need to add some other control with a click and drag behavior that resizes the window. Perhaps a line on each edge of the window?
用户需要一些交互来调整窗口大小。如果您不喜欢默认边框或夹点，则需要添加一些其他控件，通过单击和拖动行为来调整窗口大小。也许在窗口的每个边缘都有一条线？
