ThinkGeo.MapSuite.MvcEdition.FeatureSourceMarkerOverlay
<!– Class –> Represents a MarkerOverlay that dynamically creates markers from the feature source specified.
Remarks
The <strong>FeatureSourceMarkerOverlay</strong> generates markers from the features retrieved from its <strong>FeatureSource</strong>. Thus, you need to set the <strong>FeatureSource</strong> property before the marker overlay can create the markers. The <strong>ZoomLevelSet</strong> property is an entrance for you to define the marker styles on zoomlevels.
