I ve just found a great way of doing that  In my example I m using a RichTextBox but it should work with any Control   public class DisabledRichTextBox   System Windows Forms RichTextBox          See  http   wiki winehq org List Of Windows Messages      private const int WM SETFOCUS     0x07      private const int WM ENABLE       0x0A      private const int WM SETCURSOR    0x20       protected override void WndProc ref System Windows Forms Message m                if    m Msg    WM SETFOCUS    m Msg    WM ENABLE    m Msg    WM SETCURSOR               base WndProc ref m             You can safely set Enabled   true and ReadOnly   false  and it will act like a label  preventing focus  user input  cursor change  without being actually disabled   See if it works for you  Greetings

You can try this  Override the OnPaint event of the TextBox        protected override void OnPaint PaintEventArgs e         SolidBrush drawBrush   new SolidBrush ForeColor     Use the ForeColor property         Draw string to screen       e Graphics DrawString Text  Font  drawBrush  0f 0f     Use the Font property     set the ControlStyles to  UserPaint   public MyTextBox    constructor           This call is required by the Windows Forms Form Designer       this SetStyle ControlStyles UserPaint true         InitializeComponent             TODO  Add any initialization after the InitForm call     Refrence  Or you can try this hack  In Enter event set the focus  int index this Controls IndexOf this textBox1    this Controls index-1  Focus      So your control will not focussed and behave like disabled

Setting the  Read Only  as  True  is the easiest method

In addition to the answer by  spoon16 and  Cheetah  I always set the tabstop property to False on the textbox to prevent the text from being selected by default   Alternatively  you can also do something like this   private void FormFoo Load            txtFoo Select 0  0       or   private void FormFoo Load            txtFoo SelectionLength   0

NOTE  see Cheetah s answer below as it identifies a prerequisite to get this solution to work   Setting the BackColor of the TextBox     I think what you really want to do is enable the TextBox and set the ReadOnly property to true   It s a bit tricky to change the color of the text in a disabled TextBox   I think you d probably have to subclass and override the OnPaint event   ReadOnly though should give you the same result as  Enabled and allow you to maintain control of the color and formatting of the TextBox   I think it will also still support selecting and copying text from the TextBox which is not possible with a disabled TextBox   Another simple alternative is to use a Label instead of a TextBox

If you want to display text that cannot be edited or selected you can simply use a label

Additionally  in order for ForeColor to be obeyed on a TextBox marked ReadOnly  you must explicitly set the BackColor   If you want to have it still use the default BackColor  you have to make the set explicit  as the designer is too smart for its own good here   It is sufficient to set the BackColor to its current value   I do this in the Load event for the form  like so   private void FormFoo Load            txtFoo BackColor   txtFoo BackColor
