public bool EndDrawWhenLostFocus { get; set; }
true to automatically cancel all designers in an AnnAutomation when the automation loses focus; otherwise, it is false. The default value is true.
When multiple AnnAutomation objects are used in the automation, use the AnnAutomation.Active property to set one of the automations as the active one. The active automation will then process all of the mouse, touch and keyboard events. The rest of the automations are in an inactive state and will not process any events.
When an automation becomes inactive, it can have designers that are still running (for example, an edit designer selecting an object). By setting the value of CancelInactiveDesigners to true, you can cancel (or abort) all the designers in an inactive automation. This has the effect of causing all currently selected objects in the inactive automation to become de-selected.
