RibbonWindow.IsIconVisible does not seem to work

[dswfort]

Forgive my poor English...

Since update to the latest 7.0 version, I found that I can not hide the Icon on titlebar using IsIconVisable property both in xaml and viewmodel, but can hide icon in the load event.

But the pervoius alpha version such as 7.0.0-alpha0624 was worked correctly.

At last, the code in show case work correctly...

Here is my code, the RibbonWindow_Loaded function was worked correctly.

<Fluent:RibbonWindow x:Class="WpfApp1.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:local="clr-namespace:WpfApp1"
        xmlns:Fluent="urn:fluent-ribbon"
        mc:Ignorable="d" IsIconVisible="{Binding IconVisable}"
        Title="MainWindow" Height="450" Width="800" Loaded="RibbonWindow_Loaded">
    <Grid>
        <Fluent:CheckBox IsChecked="{Binding IconVisable, FallbackValue=false}">
            IsIconVisible
        </Fluent:CheckBox>
    </Grid>
</Fluent:RibbonWindow>

public partial class MainWindow : RibbonWindow, INotifyPropertyChanged
{
    private bool m_IconVisable = false;
    public bool IconVisable
    {
        get { return m_IconVisable; }
        set
        {
            if (m_IconVisable != value)
            {
                m_IconVisable = value;
                this.PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(IconVisable)));
            }
        }
    }
    public MainWindow()
    {
        InitializeComponent();
        this.DataContext = this;
        this.IsIconVisible = false;
    }

    public event PropertyChangedEventHandler PropertyChanged;

    private void RibbonWindow_Loaded(object sender, RoutedEventArgs e)
    {
        IconVisable = false;
        this.IsIconVisible = false;
    }
}

Where do you bind your IconVisable to the windows IsIconVisible property?
There does not seem to be a connection between those two properties, which should explain why it doesn't work.

[dswfort]

thank you for your reply.
The first time I tried to bind the property just in xaml, but was found that the icon didnt hide. Then I also try to hide the icon in code behind using IsIconVisible property. The icon appears to hide when RibbonWindow loaded. But when I try to resize the window, the icon displayed again... The alpha version such as 7.0.0-alpha0624 i used didnt have this problem.

Ah, the resizing part gave me the missing bit of information as i recently added a feature that hides the icon if the window gets smaller than a certain threshold and shows it again if there is enough space again. That seems to overwrite the value you set. Will try to reproduce and fix it for version 7.0.1
