Drag&Drop from outside app (example : drag from Explorer)

[Tenjim]

Hi guys,

Have you an idea about capture the drag and drop from outside application ?
I'm using Drag&Drop from Avalonia Behaviors and I want to drag from explorer (Windows) or myfinder (mac os).

Thanks in advance

Hello,

This can be done easily in native avalonia, i took inspiration from the Avalonia Source Code Control Catalog when i wanted to do this.

MainWindow.axaml

    <DockPanel>
        <Grid>
            <Border DragDrop.AllowDrop="True"
                    BorderThickness="1" BorderBrush="Black" Background="Transparent"
                    HorizontalAlignment="Center" VerticalAlignment="Center"
                    Width="200" Height="200">
                <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="Drop Here..." />
            </Border>
        </Grid>
    </DockPanel>

MainWindow.axaml.cs

        public MainWindow()
        {
            InitializeComponent();
            
            AddHandler( DragDrop.DropEvent, OnDrop);
        }

        private static void OnDrop( object? sender, DragEventArgs e )
        {
            var items = e.Data.GetFileNames(); 
            if ( items != null )
            {
                Trace.WriteLine( $"Dropped {items.FirstOrDefault()}" );
            }
        }

Thanks @Gundz, I'll look on it. I think I can use filenames from data to get what I want :)
