Resize borderless window wpf

Question

我怎么能做到这与WPF而不是Windows窗体？

Answer 1

You can do it by setting WindowChrome.

        /* Set Borderless Chrome to this Window */
        WindowChrome Resizable_BorderLess_Chrome = new WindowChrome();
        Resizable_BorderLess_Chrome.GlassFrameThickness = new Thickness(0);
        Resizable_BorderLess_Chrome.CornerRadius = new CornerRadius(0);
        Resizable_BorderLess_Chrome.CaptionHeight = 5.0;            
        WindowChrome.SetWindowChrome(this, Resizable_BorderLess_Chrome);

Add the above code inside the window constructor to obtain border less resizable window. Or you could use the window style setter to set the window chrome property:

<Setter Property="WindowChrome.WindowChrome">
        <Setter.Value>
            <WindowChrome CornerRadius="0" GlassFrameThickness="1" UseAeroCaptionButtons="False"/>
        </Setter.Value>
</Setter>

In addition to this you need to set ResizeMode to CanResize (or CanResizeWithGrip whatever that suits your purpose) and Window Style to None.
