How to adjust the height of the Mahapps window to minimum height

Question

I would like to adjust the height of the Mahapps window to very minimum (say just 5) with ShowTitlebar=false. If I try to resize the window by dragging the corner, I can resize only upto about 36 (which is titlebar height).

<Controls:MetroWindow x:Class="TestWPF.MahappsWindow1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
    Title="MahappsWindow1" Height="300" Width="300"
    UseNoneWindowStyle="True" MinHeight="1" MinWidth="1" ShowTitleBar="False">
<Grid>

</Grid>

I can resize upto with the below snap shot height: Mahapps Screenshot

However, the window height can be adjusted in Windows and ModernUI when the WindowStyle is set to none.

The below modern ui code can resize to minimum height of 1.

I can resize upto with the below snap shot height of 1: Modern UI screenshot

Is there way I can reduce the size of Mahapps window to minumum height of less than 36 without titlebar.

Answer 1

You need to divide grid in % manner than use binding:

Width="{Binding ActualWidth, ElementName=YourElementName, Mode=OneWay}"
Height="{Binding ActualHeight, ElementName=YourElementName, Mode=OneWay}"

Answer 2

This is a bug with Mahapps. It is not possible to resize the mahapps window beyond titlebar height.
