View.CustomDraw Event

Occurs at the end of each update cycle, but before the drawable swaps its front and back buffers.

Syntax

public event System.EventHandler CustomDraw

Remarks

This event is fired when the view has finished rendering a map frame, but before the drawable swaps its buffers. This is where the application should perform any drawing of its own on top of the generated map.

Custom drawing can sometimes be done directly to the underlying graphics system used by the drawable; for instance it is possible to use the native OpenGL drawing APIs if the drawable is of the correct type. If possible, however, it is recommended to use the drawing methods of the drawable itself, which will work for all types of drawables. See Custom Native Rendering for more information.

The CustomDraw event is not supported in GlobeView.

You should not perform any other work in this event other than rendering to the view that fired the event. If you need to for example modify the view or camera parameters, or maybe modify and update another View, use the Updated event instead.
