A collection of mini map layers.
Namespace : DevExpress.XtraMap
Assembly : DevExpress.XtraMap.v25.2.dll
NuGet Package : DevExpress.Win.Map
public class MiniMapLayerCollection :
DXNamedItemCollection<MiniMapLayerBase>,

Public Class MiniMapLayerCollection
Inherits DXNamedItemCollection(Of MiniMapLayerBase)
Implements ISupportSwapItems
The following members return MiniMapLayerCollection objects:
An instance of the MiniMapLayerCollection collection can be accessed using the MiniMap.Layers property.
This example demonstrates how to customize mini map layers.
To do this, create the required MiniMapLayerBase class descendant objects, configure them and add them to the MiniMap.Layers collection.
mapControl.MiniMap = CreateMiniMap(data);
MiniMap CreateMiniMap(object data) {
MiniMap miniMap = new MiniMap() {
Height = 200,
Width = 300,
Behavior = new FixedMiniMapBehavior() {
CenterPoint = new GeoPoint(-35, 140),
ZoomLevel = 3
}
};
MiniMapImageTilesLayer mapLayer = new MiniMapImageTilesLayer() {
DataProvider = new BingMapDataProvider() {
BingKey = bingKey,
Kind = BingMapKind.Area
}
};
MiniMapVectorItemsLayer vectorLayer = new MiniMapVectorItemsLayer();
ListSourceDataAdapter adapter = new ListSourceDataAdapter();
adapter.DataSource = data;
adapter.Mappings.Latitude = "Latitude";
adapter.Mappings.Longitude = "Longitude";
adapter.DefaultMapItemType = MapItemType.Dot;
adapter.PropertyMappings.Add(
new MapDotSizeMapping() { DefaultValue = 10 }
);
vectorLayer.Data = adapter;
vectorLayer.ItemStyle.Fill = Color.FromArgb(74, 212, 255);
vectorLayer.ItemStyle.Stroke = Color.Gray;
miniMap.Layers.Add(mapLayer);
miniMap.Layers.Add(vectorLayer);
return miniMap;
