C# ListView Disable Horizontal Scrollbar

There is a much simpler way to eliminate the lower scroll bar and have the vertical showing. It consists of making sure the header and if no header the rows are the width of the listview.Width - 4 and if the vertical scroll bar is show then listview.Width - Scrollbar.Width - 4;

the following code demostrates how to:

lv.Columns[0].Width = lv.Width - 4 - SystemInformation.VerticalScrollBarWidth;

@bennyyboi's answer is unsafe, as it unbalances the stack. you should use the following code instead for the DllImport:

[System.Runtime.InteropServices.DllImport("user32", CallingConvention=System.Runtime.InteropServices.CallingConvention.Winapi)]
[return: System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.Bool)]

private static extern bool ShowScrollBar(IntPtr hwnd, int wBar, [System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.Bool)] bool bShow);

Andreas Reiff covers this in his comment above after looking again, so I guess here it is all nicely formatted.

You could try something like this, I used in a project once and it worked:

[DllImport ("user32")]
private static extern long ShowScrollBar (long hwnd , long wBar, long bShow);
long SB_HORZ = 0;
long SB_VERT = 1;
long SB_BOTH = 3;

private void HideHorizontalScrollBar ()
{
    ShowScrollBar(listView1.Handle.ToInt64(), SB_HORZ, 0);
}

Hope it helps.
