Namespace: DevExpress.XtraMap

Assembly: DevExpress.XtraMap.v18.1.dll

Declaration

C#

public class MiniMapImageTilesLayer :
    MiniMapLayerBase

VB.NET

Public Class MiniMapImageTilesLayer
    Inherits MiniMapLayerBase

Example

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.
