DynamicMiniMapBehavior Class

This class provides the dynamic mini map behavior.

Namespace: DevExpress.Xpf.Map

Assembly: DevExpress.Xpf.Map.v19.2.dll

Declaration

C#

public class DynamicMiniMapBehavior :
    MiniMapBehavior

VB.NET

Public Class DynamicMiniMapBehavior
    Inherits MiniMapBehavior

Remarks

• This class introduces the DynamicMiniMapBehavior.ZoomOffset property to specify an offset of the mini map, and DynamicMiniMapBehavior.MinZoomLevel and DynamicMiniMapBehavior.MaxZoomLevel to specify the minimum and maximum zoom levels which can be used by the mini map.

• When a mini map operates in this mode, a mini map’s zoom level and center point change according to the zoom level and center point of the owner map. The following images demonstrates dynamic behavior mode.

  

Example

This example demonstrates how to customize mini map behavior.

The Mini map supports two behavior types.

• FixedMiniMapBehavior. The mini map’s zoom level and a center point are fixed.
• DynamicMiniMapBehavior. The mini map’s zoom level and a center point are based on the map’s zoom level and center point.

To specify the behavior, assign the required behavior class to the MiniMap.Behavior property.
