Checkbox on the header of a Listview

[Natural_Demon]

i have made this piece of code, to a checkbox on the header: wel not realy on the headr, but situated there. (class ColumnHeader doesn't provide much, like for example: OnpaintEvent. but i need some help with the special effects. if you hoover the mouse over the header, the mousehover effect of the header hides the checkbox, bringing it to the background. i would like to have the checkbox ontop @ all time. using windows 7.

using System;
using System.Drawing;
using System.Runtime.InteropServices;
using System.Windows.Forms;

namespace Listview_Colum_header_checkbox
{
    class CCehckBox : CheckBox
    {
        public CCehckBox()
        {
            Width = 14;
            Height = 14;
            //a
            //ValidationConstraints.Visible
            //AutoValidate.EnablePreventFocusChange;
        }

        protected override void OnPaint(PaintEventArgs pevent)
        {
            Invalidate();
            base.OnPaint(pevent);
        }
    }

    class CListViewHeader : ColumnHeader
    {
        void CListViewHeader()
        {
        }
    }

    class CListview : ListView
    {
        private readonly CCehckBox _cCehckBox = new CCehckBox();
        private readonly ColumnHeader _header1 = new ColumnHeader();
        private readonly ColumnHeader _header2 = new ColumnHeader();
        private readonly ColumnHeader _header3 = new ColumnHeader();

        #region  PInvoke Declarations

        [DllImport("user32")]
        private static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);

        #endregion

        public CListview()
        {
            View = View.Details;

            _header1 = Columns.Add("Name");
            _header1.Width = (Location.X + 5) + 6;
            _header1.AutoResize(ColumnHeaderAutoResizeStyle.ColumnContent);
            _header1.Name = "CheckBox";
            _header1.DisplayIndex = 0;

            _header2 = Columns.Add("bah");
            _header2.Width = (Width - 20) - 50;

            _header3 = Columns.Add("boh");
            _header3.Width = 50;

            var wijd = _cCehckBox.Width;
            var hoog = _cCehckBox.Height;
            _cCehckBox.Location = new Point(Location.X+ 5, Location.Y + 5);
        }


        protected override void OnColumnWidthChanged(ColumnWidthChangedEventArgs e)
        {
            
            if(e.ColumnIndex == 0)
            {
                //MessageBox.Show(e.ColumnIndex.ToString());

Imho, your best bet would be to use a class derived from ColumnHeader[^]. /ravi

i tried that, but it doesn't look 'ColumnHeader' it provides me the nessesary properties to do this.
