Remarks

The ::CreatePreSketchFeedback() method is called by the controller to initiate the creation of a custom feedback object associated to the EditSketchExtension.

This feedback object will be used prior that of the feedback object associated to the Edit Sketch.

Use this method to create your PreSketchFeedback object and pass it out so the Editor can use it.

[C#]

ESRI.ArcGIS.Display.IDisplayFeedback IEditSketchExtension2.CreatePreSketchFeedback()
{
  //m_editor has a reference to IEditor.
  IEditSketch editSketch = m_editor as IEditSketch;
  IPointCollection points = editSketch.Geometry as IPointCollection;

  //customFeedback is a custom feedback object.
  DispFeedback customFeedback = new DispFeedback();
  customFeedback.StartPt = points.get_Point(0);

  return customFeedback;
}
