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.

    <dxm:MiniMapImageTilesLayer>
        <dxm:BingMapDataProvider BingKey="{StaticResource bingKey}"/>
    </dxm:MiniMapImageTilesLayer>
</dxm:MiniMap>
