Hi John,


ListBox doesnot provide a interface for your to manipulate the scrollbar
directly. As a workaround, you can try sending WM_VSCROLL message via
PInvoke. For
example:


Class Win32
{
[DllImport("User32.Dll")]
public static extern bool SendMessage(IntPtr hWnd,int Msg,int
wParam,int lParam);
public const int WM_VSCROLL = 0x0115;
public const int SB_LINEDOWN = 1;



}


Win32.SendMessage(listBox1.Handle,Win32.WM_VSCROLL,Win32.SB_LINEDOWN,0);

Hope this helps.


Regards,

Luke

Googling "listbox onscroll", this thread is the third hit in the list. Your post linking to google is about as helpful as tits on a bull. Let's assume everyone was a giant douchenozzle like yourself, and in reply to every question simply posted a link to google... we'd have a results list of google search links. Congratulations on contributing to useless recursion. :cheers:

Thanks, Luke. This is the sort of information which someone who DOES search for a particular topic expects to find.
