Hi,
Subclass the ListView control and then add the method for horizontal scrolling as given by Ken over here
Code Snippet
[DllImport("user32")]
static extern IntPtr SendMessage(IntPtr Handle, Int32 msg, IntPtr wParam,
IntPtr lParam);
protected void ScrollH(int pixelsToScroll)
{
const Int32 LVM_FIRST = 0x1000;
const Int32 LVM_SCROLL = LVM_FIRST + 20;
SendMessage(lvwList.Handle, LVM_SCROLL, (IntPtr) pixelsToScroll,
IntPtr.Zero);
}
To know when the user scrolls horizonatally, you'll need to capture the
WM_HSCROLL message in the WndProc() method, e.g.
protected override void WndProc(ref Message m)
{
const Int32 WM_HSCROLL = 0x114;
if (m.Msg == WM_HSCROLL)
HandleHorizontalScroll();
base.WndProc(ref m);
}
HTH,
