Properties

Name

String: Returns the name of the property that has changed.

One of "zoom", "tilt", "mapTypeId", "center", "bounds", "heading" or "projection".

Value

Object: Returns the new value of the property.

The type depends on Name: a LatLng for "center", a LatLngBounds for "bounds", a number for "zoom", "tilt" and "heading", and a string for "mapTypeId". It can be null when the client cannot serialize the value.

Tracking the zoom level and the center of the map:

private void googleMap1_MapPropertyChanged(object sender, MapPropertyChangedEventArgs e)
{
    switch (e.Name)
    {
        case "zoom":
            this.labelZoom.Text = "Zoom: " + Convert.ToInt32(e.Value);
            break;

        case "center":
            var center = (LatLng)e.Value;
            this.labelCenter.Text = $"{center.Lat:F4}, {center.Lng:F4}";
            break;
    }
}
