Disable default zoom functionality on GoView


I want to disable default zoom functionality on GoView while scrolling mouse scroll button with pressing Ctrl key.
How can i do it?
Thanks & Regards

[code] [Serializable]
public class NoZoomToolManager : GoToolManager {
public NoZoomToolManager(GoView view) : base(view) { }

public override void DoMouseWheel() {
  if (this.LastInput.Control) return;  // ignore wheel events when modified by Control key

Replace the standard GoToolManager by:

goView1.Tool = goView1.DefaultTool = new NoZoomToolManager(goView1);
