Undo Deleted Note and Fire Undo Pre- and Post-Notify Events Example (C#)

This example demonstrates firing Undo pre- and post-notification events in a drawing document.

//---------------------------------------------------------------------------

// Preconditions: Open:

// <SolidWorks_install_dir>\samples\tutorial\driveworksxpress\mobile gantry.slddrw.

//

// The right-side note in Drawing View 3 is selected and then deleted.

// The latter action is then undone and pre- and post-notification

// events are fired indicating that an undo action is about to occur

// and has occurred.

//

// Postconditions: None
