How to re-size window in WPF when Allow Transparent is True

Question

As you known, when allow transparent property is true, the border of window is hidden and we cannot re-size the window. We only re-size the window if we set ResizeMode is CanResizeWithGrip, but the solution is not good because we can re-size window when it's maximized and change by right corner of the window instead of all of 4 corners, so the question is how to how to re-size window in WPF when Allow Transparent is True without using CanResizeWithGrip?

Thanks in advance!

My expected is set window can re-size with hidden border, so finally I have found a solution to handle that, you can follow the below code:

<WindowChrome.WindowChrome>
    <WindowChrome     
        CaptionHeight="1"  
        CornerRadius ="0"
        ResizeBorderThickness="4"         
        GlassFrameThickness="0">
    </WindowChrome>
</WindowChrome.WindowChrome>

Please add more discussion if you want to know more information.

Well, this is actually pretty easy. There is a property on the Window named ResizeMode, and if you set it to "CanResizeWithGrip", then a ResizeGrip control is placed on your window automatically, and if you run the app, it will, correctly, resize your window.
