OnItemSelect event has no ShapeData

[Miguel Oliveira]

While building a Blazor component using SfMaps to display a 'Normal' geometry layer, I made a start by using Syncfusion's "Bus seat booking" sample data, but when ItemSelect events are triggered ShapeData is null. Is this a bug, or am I missing something?

@using Syncfusion.Blazor.Maps
 
<SfMaps @ref="MapInstance" ProjectionType="ProjectionType.Equirectangular">
    <MapsEvents OnMarkerClick="OnMarkerClick" OnItemSelect="OnItemSelect" />
    <MapsLayers>
        <MapsLayer LayerType="ShapeLayerType.Geometry" GeometryType="GeometryType.Normal" ShapeData="@ShapeDataSource">
            <MapsShapeSettings Fill="gray" ColorValuePath="fill">
                <MapsShapeBorder Color="#FFFFFF" Width="1"></MapsShapeBorder>
            </MapsShapeSettings>
            <MapsLayerSelectionSettings Enable="true" Opacity="1"></MapsLayerSelectionSettings>
        </MapsLayer>
    </MapsLayers>
    <MapsZoomSettings Enable="true" />
</SfMaps>
 
@code{
    protected SfMaps MapInstance { get; set; }
 
    protected MapDataSettings ShapeDataSource => new MapDataSettings
    {
        dataOptions = "assets/seat.json"
    };

    protected void OnItemSelect(ISelectionEventArgs args)
    {
        var dump = args.ShapeData?.ToString() ?? string.Empty; // should output something like -> {"seatno":12,"fill":"gray"}
        Console.WriteLine("OnItemSelect: {0}", dump);
    }
 
    protected class MapDataSettings
    {
        public string dataOptions { get; set; }
 
        public bool async => true;
 
        public string type => "GET";
    };
}

Please find the code snippet for the getting ShapeData below in the event. 

<SfMaps> 

    <MapsEvents OnItemSelect="OnItemSelect"/> 

    <MapsLayers> 

        <MapsLayer TValue="MapDataSettings" ShapeData='new {dataOptions= "https://cdn.syncfusion.com/maps/map-data/world-map.json"}'> 

            <MapsShapeSettings Fill="gray" ColorValuePath="fill"> 

                <MapsShapeBorder Color="#FFFFFF" Width="1"></MapsShapeBorder> 

            </MapsShapeSettings> 

            <MapsLayerSelectionSettings Enable="true" Opacity="1"></MapsLayerSelectionSettings> 

        </MapsLayer> 

    </MapsLayers> 

</SfMaps> 

  

We have created the sample application to demonstrate the same and it can be downloaded from the below link.

In the above sample, we have rendered a world map. When we select the shape in the map, the OnItemSelect event gets triggered.
