Button - Left Mouse Click + Ctrl

[stephannn]

Hi,
in WPF I use an InputBindings to perform a special action when a button is clicked and at the same time a key is pushed:

<Button Name="button_update" Command="{Binding UpdateCommand}" Content="Update " Grid.Column="0" >
    <Button.InputBindings>
        <MouseBinding Gesture="Ctrl+LeftClick" Command="{Binding UpdateCtrlCommand}"/>
    </Button.InputBindings>
</Button>

As far as I can see I cannot do it that way in Avalonia but I have to use a pointer event: https://docs.avaloniaui.net/docs/concepts/input/pointer

However, using PointerPressed with a function seems only to work with the right click of the mouse:

<Button Name="button_update" Content="Update" PointerPressed="Button_PointerPressed" Grid.Row="0" HorizontalContentAlignment="Center" HorizontalAlignment="Stretch"/>

        private void Button_PointerPressed(object? sender, PointerPressedEventArgs e)
        {
            if (e.GetCurrentPoint(this).Properties.IsLeftButtonPressed && e.KeyModifiers.HasFlag(KeyModifiers.Control))
            {
                System.Diagnostics.Debug.WriteLine("Button + Ctrl was clicked");
            }
        }

but not the left click.

Someone has an idea how I can fix that?
Thanks
Stephan

You need to use AddHandler to subscribe to the event from code-behind with a tunneling strategy here. Left click events will be handled by the Button itself, so you'll never get it with the default bubbling strategy.
