Blazor Map Property ZoomFactor doesn't appear to work when bound to property.

I am writing an Blazor Server application that allows the map to go to a particular longitude and latitude when I click on an entry in a datagrid. I'd like the map zoomed out a little at the start but zoom in when an entry in the datagrid is clicked.

I'm using version

This works perfectly for longitude and latitude but not for zoomFactor. The zoom remains fixed.


        <MapsZoomSettings Enable="true" ZoomFactor="@ZoomFactor" MaxZoom="20"></MapsZoomSettings>

        <MapsCenterPosition Latitude="@MapLatitude" Longitude="@MapLongitude"></MapsCenterPosition>


            <MapsLayer UrlTemplate="https://tile.openstreetmap.org/level/tileX/tileY.png" TValue="string">


                    <MapsMarker Visible="true" Height="25" Width="15" DataSource="Cities" TValue="City">






public void RowSelectHandler(RowSelectEventArgs args)


MapLatitude = args.Data.Latitude;

MapLongitude = args.Data.Longitude;

ZoomFactor = 12;


public double MapLatitude { get; set; } = 25.54244147012483;

public double MapLongitude { get; set; } = -89.62646484375;

public double ZoomFactor { get; set; } = 4;
