Has any one successfully trapped the event of mouse scroll in a web browerser component?

I have two web browser controls i would like to scroll at the same time.

But there are no scroll events for web browsers.

**I would like to create an event something like this below? has any one done or seen this before?**

```
 private void webCompareSQL_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
                Document.Window.AttachEventHandler("OnScroll");            
        }

```

Here i would call my event and proceed with the code.

```
private void windowEvents_OnScroll()
{
int nPos = GetScrollPos(webCompareSQL.Handle, (int)ScrollBarType.SbVert); 
nPos <<= 16;
uint wParam = (uint)ScrollBarCommands.SB_THUMBPOSITION | (uint)nPos;
SendMessage(WebPrevSQL.Handle, (int)Message.WM_VSCROLL, new IntPtr(wParam), new IntPtr(0));        
}

```

I have found this code but don't know how to use it. its an event.

```
webCompareSQL.Document.Window.Scroll

```
