When I set a TextBox to Readonly or set Enabled to false, the text color is gray. How can I force it to be the color specified in the ForeColor property of the TextBox?

You can download a VB.NET sample.

Override the OnPaint event of the TextBox. For example:

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
}

Note: You need to set the ControlStyles to "UserPaint" in the constructor.

public MyTextBox()
{
  // This call is required by the Windows.Forms Form Designer.
  SetStyle( ControlStyles.UserPaint, true );
  InitializeComponent();
}
