Note: The page was created before Map Suite 10. Map Suite 10.0 organized many classes into new namespaces and assemblies as well as had a few minor breaks in compatibility. The majority of previously built code should work without modification assuming the new namespaces are added. For guidance on upgrading your existing code, please check out MapSuite 10 Upgrade Guide.
This class inherits from InterativeOverlay abstract class. This specified overlay describle the TrackShape interative process with MapControl using Mouse or Keyborad.
Default constructor of the class. If you use this constructor, please set the properties correctly or it will use their default values.

This method draws the TrackInterativeOverlay.
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.
This method initializes the overlay canvas such as width, height and z-index for first time.

This property override the logic in its base class by watching the feature count in trackShapeLayer. If it is empty ,we can skip drawing it for better performance.

The default mode is TrackMode.None which means you cannot draw or edit features at client. By setting the mode to TrackMode.Point, TrackMode.Line, TrackMode.Polygon etc., you could add point, line or polygon to the FeatureOverlay. Setting the mode to TrackMode.Edit, you could edit the shapes at the client side.
