Steps to reproduce
A default WPF app with latest version of the library and the following xaml and code behind for main window:
<cz:WindowChromeWindow x:Class="TestWpfApp.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:cz="clr-namespace:ControlzEx;assembly=ControlzEx"
xmlns:czb="clr-namespace:ControlzEx.Behaviors;assembly=ControlzEx"
xmlns:local="clr-namespace:TestWpfApp"
mc:Ignorable="d"
WindowStartupLocation="CenterScreen"
Title="MainWindow" Height="450" Width="800">
<StackPanel Background="White" VerticalAlignment="Top" HorizontalAlignment="Right">
<Button Height="48"
Width="48"
czb:NonClientControlProperties.HitTestResult="CLOSE"
czb:NonClientControlProperties.ClickStrategy="AutomationPeer"
Click="OnCloseButtonClick">
<Button.Style>
<Style TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid Background="{TemplateBinding Background}">
<Viewbox Height="20" Width="20">
<Rectangle Fill="Blue" Height="100" Width="100">
</Rectangle>
</Viewbox>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Red" />
</Trigger>
<Trigger Property="czb:NonClientControlProperties.IsNCMouseOver" Value="True">
<Setter Property="Background" Value="Red" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Button.Style>
</Button>
</StackPanel>
</cz:WindowChromeWindow>
using ControlzEx;
namespace TestWpfApp;
public partial class MainWindow : WindowChromeWindow
{
public MainWindow()
{
InitializeComponent();
}
private void OnCloseButtonClick(object sender, System.Windows.RoutedEventArgs e)
{
Close();
}
}
Expected behavior
When I hover over the button, including the viewbox area, hover and click logic works
Actual behavior
When I hover the view box area (blue rectangle), hover and click behavior stop working:

If you remove czb:NonClientControlProperties.HitTestResult="CLOSE" from the xaml letting WPF handle client area events, hovering over view box still counts as IsMouseOver, so I expect IsNCMouseOver to work the same way
Environment
- ControlzEx: 7.0.2
- Windows 10.0.19045
- .NET 10.0
