Draw(GeoCanvas)

• This method draws the Overlay.

• This method is the concrete wrapper for the abstract method DrawCore. This method draws the representation of the overlay based on the extent you provided. As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.

DrawCore(GeoCanvas)

• This method draws the GoogleMapsOverlay.

• This method draws the representation of the overlay based on the extent you provided. When implementing this abstract method, consider each feature and its column data values. You can use the full power of the GeoCanvas to do the drawing. If you need column data for a feature, be sure to override the GetRequiredColumnNamesCore and add the columns you need to the collection. In many of the styles, we add properties that allow the user to specify which field they need; then, in the GetRequiredColumnNamesCore, we read that property and add it to the collection.
