NavigationLines

[Raul]

Hi is it possible to render navigation lines dynamically?    

<SfMaps @ref="map">

        <MapsZoomSettings Enable="true" ShouldZoomInitially="true" MaxZoom="18" ZoomFactor="20" MouseWheelZoom="true" Toolbars='new string[]{"Zoom", "ZoomIn", "ZoomOut", "Pan", "Reset" }'></MapsZoomSettings>

        <MapsCenterPosition Latitude="19.7036417" Longitude="-101.2761651"></MapsCenterPosition>

        <MapsLayers>

            <MapsLayer LayerType="ShapeLayerType.OSM">

                <MapsMarkerSettings>

                    <MapsMarker Visible="true"

                                Height="25"

                                Width="15"

                                LatitudeValuePath="Latitude"

                                LongitudeValuePath="Longitude"

                                ColorValuePath="MarkerColor"

                                DataSource="LastRecords">

                        <MapsMarkerTooltipSettings ValuePath="DeviceTime" Visible="true"></MapsMarkerTooltipSettings>

                    </MapsMarker>

                </MapsMarkerSettings>

                <MapsMarkerClusterSettings AllowClustering="false" AllowClusterExpand="true" Shape="MarkerType.Circle" Height="40" Width="40">

                    <MapsLayerMarkerClusterLabelStyle Color="white"></MapsLayerMarkerClusterLabelStyle>

                </MapsMarkerClusterSettings>

                <MapsNavigationLines>

                    @if (LatLonD!=null)

                    {

                        @foreach (var record in LatLon)

                        {

                            <MapsNavigationLine Visible="true" Angle="0" Color="black" Width="10" DashArray="1" Latitude="record.Key" Longitude="record.Value"></MapsNavigationLine>

                        }

                        map.Refresh();

                    }

                </MapsNavigationLines>

            </MapsLayer>

        </MapsLayers>

    </SfMaps>

Hi Raul, 

  

Thank you for contacting Syncfusion support. 

  

We do not have support for adding the navigation lines in the Maps component using the declarative syntax in the Blazor application dynamically. However, we have considered this as a feature and logged a feature report for the same. The fix for this reported scenario will be included in any of our upcoming releases. Please follow the below feedback link for further updates. 

  

https://www.syncfusion.com/feedback/14843 

  

At present, to render the navigation lines, we need to render the navigation lines using individual MapsNavigationLine tags. 

  

Please let us know if you need further assistance.

Hello Swetha,

this works basically fine. But when I change the MapNavigationLines dynamically, they are not cleared properly.

Please check the attached example. It is your Blazor example. Please use the Button on the first page "View Issue" to navigate to the example. If you hit the Button "Toggle" below the map, I would expect the already shown lines to disappear and the new lines to appear. But both groups are shown.

I had to remove wwwroot from your example, since it is over 30 MB. You can just use your example from:

https://github.com/syncfusion/blazor-samples

and replace Index.razor and NavigationLines.razor.

Best regards

Michael
