Question

When a WinForm element is disabled, it sort of grays out. Is it possible to disable an element, but adjust the disabled style so it still looks enabled (not grayed out)?

Answer 1

Preventing a focusable control from taking the focus takes a number of counter-measures. You will have to include a control that does take the focus for this class to be resist all attempts:

using System;
using System.Windows.Forms;

class RichLabel : RichTextBox {
    public RichLabel() {
        this.ReadOnly = true;
        this.TabStop = false;
        this.SetStyle(ControlStyles.Selectable, false);
    }
    protected override void OnEnter(EventArgs e) {
        if (!DesignMode) this.Parent.SelectNextControl(this, true, true, true, true);
        base.OnEnter(e);
    }
    protected override void WndProc(ref Message m) {
        if (m.Msg < 0x201 || m.Msg > 0x20e)
            base.WndProc(ref m);
    }
}
