Native-like Caption Button for WPF

Provides caption buttons in native-like style for WindowChrome.

Features

You can decide for every button:

• Visibility (Visible, Collapsed, Hidden)
• IsEnabled (true, false)
• Height (typically 30 and 48 DIP)

Simple example

Just add CaptionButtonBar to your window, every button will change the window state properly. WindowChrome.IsHitTestVisibleInChrome has been set in the ControlTemplate and it will find owner window by Window.GetWindow(this) itself and react to Window.Activated, Window.Deactivated, Window.StateChanged events.

<Window
    xmlns:CaptionButtons="clr-namespace:SuGarToolkit.WPF.Controls.CaptionButtons;assembly=SuGarToolkit.WPF.Controls.CaptionButtons"
    xmlns:system="clr-namespace:System;assembly=netstandard"
    Title="SuGarToolkit.WPF.Controls.CaptionButtons"
    StateChanged="Window_StateChanged"
    ...>

    <WindowChrome.WindowChrome>
        <WindowChrome
            x:Name="WindowChrome"
            CaptionHeight="30"
            UseAeroCaptionButtons="False" />
    </WindowChrome.WindowChrome>

    <Grid x:Name="LayoutRoot">
        <Grid.RowDefinitions>
            <RowDefinition Height="auto" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>

        <Grid x:Name="TitleBarArea" Grid.Row="0">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*" />
                <ColumnDefinition Width="auto" />
            </Grid.ColumnDefinitions>

            <CaptionButtons:CaptionButtonBar
                Grid.Column="1"
                Height="30"
                IsMaximizeButtonEnabled="False"
                IsMinimizeButtonEnabled="False" />
        </Grid>

        <StackPanel Grid.Row="1">
            ...
        </StackPanel>
    </Grid>

</Window>

When the window maximized, content near the edge of the window will be out of the range of the screen. To solve this problem, there is a feasible way: change the content margin when Window.StateChanged.

private void Window_StateChanged(object sender, EventArgs e)
{
    switch (WindowState)
    {
        case WindowState.Maximized:
            double left = SystemParameters.ResizeFrameVerticalBorderWidth + SystemParameters.FixedFrameVerticalBorderWidth + SystemParameters.BorderWidth;
            double top = SystemParameters.ResizeFrameHorizontalBorderHeight + SystemParameters.FixedFrameHorizontalBorderHeight + SystemParameters.BorderWidth;
            LayoutRoot.Margin = new Thickness(left, top, left, top);
            break;
        default:
            LayoutRoot.Margin = new Thickness(0);
            break;
    }
}

(works properly on Windows 10 and Windows 11)
