Introduction

This is based on article at http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2384558&SiteID=1&mode=1 where I extended the code provided by Zhi-Xin Ye in the post to create a CheckListBox that supports ReadOnly. Unlike CheckedListBox control which can only be Disabled.

Using the code

        private void Form1_Load(object sender, EventArgs e)
        {
            //ReadOnly CheckListBox
            checkListBox1.BackColor = Color.FromKnownColor(KnownColor.ControlLight);
            checkListBox1.SelectionMode = SelectionMode.None;

            CheckBox[] boxes = new CheckBox[100];
            for (int i = 0; i < 100; i++)
            {
                CheckBox box = new CheckBox();
                box.Checked = true;
                box.Enabled = false;
                box.Text = "box" + i.ToString();
                boxes[i] = box;
            }
            checkListBox1.AddCheckBoxes(boxes);

            //Normal CheckListBox
            boxes = new CheckBox[100];
            for (int i = 0; i < 100; i++)
            {
                CheckBox box = new CheckBox();
                box.Text = "box" + i.ToString();
                boxes[i] = box;
            }
            checkListBox2.AddCheckBoxes(boxes);
        } 

  

Points of Interest

Like I mentioned, mouse wheel scroll is quite slow and there"s flickering when I use scrollbar. This is just a start, hopefully I will be able to make it better in future.
