基于对ListBox的CheckListBox支持只读

{A}{S0}简介
{A2}我扩展提供支持只读不像CheckedListBox控件只能被禁用后，以创建一个CheckListBox叶志新代码这是基于。使用代码
演示项目包含如下的代码:

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);

}
