Is there a way to get the scrollbar height and width?

Question

I'm trying to get the height and width of the scrollbars that are displayed on a ListView. Is there an easy way to do this? I did some google'ing and it looks like it might be a system setting. I'm just not sure where to look.

Answer 1

Yes, it is a system setting. Use SystemInformation.HorizontalScrollBarHeight and SystemInformation.VerticalScrollBarWidth.

Namespace: System.Windows.Forms

Answer 2

On .Net CF, where SystemInformation.HorizontalScrollBarHeight and SystemInformation.VerticalScrollBarWidth don't exist, some P/Invoke is required:

public sealed class Native
{
    public static Int32 GetVerticalScrollbarWidth()
    {
        return GetSystemMetrics(SM_CXVSCROLL);
    }

    public Int32 GetHorizontalScrollbarHeight()
    {
        return GetSystemMetrics(SM_CYHSCROLL);
    }

    [DllImport("coredll.dll", SetLastError = true)]
    public static extern Int32 GetSystemMetrics(Int32 index);

    public const Int32
        SM_CXVSCROLL = 2,
        SM_CYHSCROLL = 3;
}
