Example

This example demonstrates how to implement a map overlay that looks like a button with an icon:

The MapOverlayItemBase.Alignment allows to layout items properly in the example.

C#

// 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;
}

VB

' In the Form_Load event handler.
Dim Resources As ComponentResourceManager = New ComponentResourceManager(GetType(Form1))
Dim overlay As MapOverlay = CreateButtonLikeOverlay(
    image:=LoadOkIconFromResources(),
    text:="OK"
)
overlay.Alignment = ContentAlignment.TopLeft
overlay.Margin = new Padding(16)
MapControl1.Overlays.Add(overlay)
' ...

Private Function CreateButtonLikeOverlay(image As Image, text As String) As MapOverlay
    Dim overlay As MapOverlay = New MapOverlay()
    overlay.Padding = new Padding(8)
    overlay.Items.Add(New MapOverlayTextItem() With {
        .Text = text,
        .Alignment = ContentAlignment.MiddleRight
    })
    overlay.Items.Add(New MapOverlayImageItem With {
        .Image = image,
        .Alignment = ContentAlignment.MiddleLeft
    })
    Return overlay
End Function
