Overlay Item Alignment Sample

// In the Form_Load event handler.
MapOverlay overlay = CreateButtonLikeOverlay(
    image: LoadOkIconFromResources(),
    text: "OK"
);
overlay.Alignment = ContentAlignment.TopLeft;
overlay.Margin = new Padding(16);
mapControl1.Overlays.Add(overlay);
// ...

private MapOverlay CreateButtonLikeOverlay(Image image, String text) {
    MapOverlay overlay = new MapOverlay();
    overlay.Padding = new Padding(8);
    overlay.Items.Add(new MapOverlayTextItem {
        Text = text,
        Alignment = ContentAlignment.MiddleRight
    });
    overlay.Items.Add(new MapOverlayImageItem {
        Image = image,
        Alignment = ContentAlignment.MiddleLeft
    });
    return overlay;
}
