Stop map resetting to 0,0 on double-tap

[James Lavery]

I've got the following XAML:

HorizontalOptions="FillAndExpand"

EnablePanning="False"

ZoomLevel="10">

GeoCoordinateChanged="ImageryLayer_GeoCoordinateChanged"

ZoomLevelChanging="Handle_ZoomLevelChanging"

RequestTileUri="Handle_RequestTileUri"

CanCacheTiles="False"

LayerType="OSM"

GeoCoordinates="50.8088760375977,-1.18579387664795">

Which shows the map fine.

However, when the user double-taps on the map, it recenters to lat/long of 0/0.

How can I stop it doing this?

I was hoping I could cancel theGeoCoordinateChanged event, (similar to cancelling the ZoomLevelChanging event), but there's noCancel property of the event arguments.

Query: How to restrict the zoom out while double tapping?  

  

Your requirement has been achieved by disabling the ResetOnDoubleTap property as per in below code snippet  

   

Code Snippet [XAML]  

            <maps:SfMaps x:Name="maps" HorizontalOptions="FillAndExpand" EnablePanning="False" ZoomLevel="10">   

                <maps:SfMaps.Layers >   

                    <maps:ImageryLayer x:Name="imagerylayer" GeoCoordinateChanged="Imagerylayer_GeoCoordinateChanged" ZoomLevelChanging="Imagerylayer_ZoomLevelChanging"   

                     RequestTileUri="Imagerylayer_RequestTileUri"  CanCacheTiles="False" LayerType="OSM" ResetOnDoubleTap="False"   

                     GeoCoordinates="50.8088760375977,-1.18579387664795">   

                    </maps:ImageryLayer>   

                </maps:SfMaps.Layers>   

            </maps:SfMaps>
