How to display custom context menu during create feature task?

Question

I have a created a custom context menu using ICommandBar and am displaying it on create feature mouse-down right click. I am constructing a point collection on each mouse down and then creating a polyline. For each point I am refreshing using EditSketch.RefreshSketch().

On right click, I created a custom context menu to finish the sketch. Sometimes, I get the default "Sketch Tool/Select Elements" context menu, which I do not want to get on right click.

The code that I'm using to display the context menu:

public override void OnMouseDown(int Button, int Shift, int X, int Y)
{
  if (Button == 2)
  {
    _objContextMenu.Popup(0, 0);
  }
}

You need to 'short circuit' the OnContextMenu and tell ArcGIS that everything's sorted.

public override bool OnContextMenu(int X, int Y)

{
      return true; // or allow some condition where the context menu is allowed
}
