Hide "TitleBarMinMaxCloseContainer"

[Petrarca181]

Hello, as currently not possible to hide maximize/minimize button I was using this:

Style TargetType="ContentControl" x:Key="WindowChromeStyle">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ContentControl">
<Grid x:Name="LayoutRoot">
<Grid x:Name="TitleBarMinMaxCloseContainer" Visibility="Collapsed">
<Grid x:Name="MinMaxCloseContainer"/>
</Grid>
<ContentPresenter x:Name="ClientAreaPresenter"
Content="{TemplateBinding Content}"
ContentTemplate="{TemplateBinding ContentTemplate}"
ContentTransitions="{TemplateBinding ContentTransitions}"
Foreground="{TemplateBinding Foreground}"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
But now I'm using WinUIEX and that style crashes my app. So I tried this:
WindowManager.Get(this).IsMinimizable = false;
WindowManager.Get(this).IsMaximizable = false;

still nothing. Any Ideas? It's possible to navigate through VisualTreeHelper in code behind to the ContentControl?

It would be nice to know precisely what you are doing here.

The standard title bar removes these buttons without issue.

Microsoft.UI.Windowing.AppWindowTitleBar.ExtendsContentIntoTitleBar removes these buttons without issue.

It is only Microsoft.UI.Xaml.Window.ExtendsContentIntoTitleBar that ignores the window style.

So it is possible, the issue is that one of the methods to extend the content into the title bar does a poor job of mirroring the style set on the window, and the use of AppWindowTitleBar is the recommended method, assuming there are no bugs.

I cleared bin and obj folder now after rebuilding the project WindowManager.Get(this).IsMinimizable = false;
WindowManager.Get(this).IsMaximizable = false; hide those buttons. Idk why and how.
