Adding AddRange method to ShapesList

[frankvandenbergh]

First of all: best wishes and thanks for this component

I make use of OpenStreetMap. Setting markers is a bit slow (I've about 2000 markers, with about all different icons). Is the code below correct or is there a better approach or could you add an AddRange method?

<OpenStreetMap>
    <Layers>
        <Layer @ref="_layer" LayerType="LayerType.Vector" SourceType="SourceType.Vector">
        </Layer>
    </Layers>
</OpenStreetMap>


private void DrawSensorData()
{
    if (sensorData != null && sensorData.Count > 0)
    {
        _layer.ShapesList.Clear();
        int radius2 = 13;
        foreach (var sensor in sensorData)
        {
            Marker marker2;
            string svg = "data:image/svg+xml;utf8, " + MarkerHelper.CreateSensorSvg(SelectedParticulate, sensor.Value);
            marker2 = new Marker(new Coordinate(sensor.Longitude, sensor.Latitude), svg, radius2 * 2, radius2 * 2, radius2, radius2);
            marker2.Popup = true;
            marker2.Properties.Add("SensorId", sensor.Id);
            marker2.Properties.Add("Value", sensor.Value);
            marker2.Properties.Add("MinValue", sensor.MinValue);
            marker2.Properties.Add("MaxValue", sensor.MaxValue);
            marker2.Properties.Add("Address", sensor.Address);

            _layer.ShapesList.Add(marker2);
        }
    }
}

Indeed ShapesList or LayersList are both ObservableCollection so adding one at a time trigger the event each time, when you know you have a complete list it could be better to add everything once.

2.4.0 released with a AddRange method on ShapesList Collection for bulk inserts.
