When you set the property of a TextBox control to ReadOnly true the text becomes grayed out. That's the default behavior.

If you have a requirement to show it in Red, then you shouldn't set the ReadOnly property but rather handle the TextChanged events manually and keep the old value intact. But i don't recommend it.

@BrianSnow - Well, because it tends to get messy if you start working in the code-behind rather than having your UI encapsulated and loosely coupled to the logic behind. – dutzu Apr 20 '15 at 08:05
A better approach would be to have the texbox with the behavior you want as a custom control (in case you intend on reusing it) – dutzu Apr 20 '15 at 08:11

A simpler solution is just to set the textbox BackColor to itself. that is textBox1.BackColor = textBox1.BackColor; textBox1.ForeColor = Color.Red; textBox1.ReadOnly = true; This sets the colors to custom – davehay Jul 13 '16 at 09:07

Try to cancel the event for KeyPress:

textBox1.Text = "Test";
textBox1.ForeColor = Color.Red;
textBox1.KeyPress += new KeyPressEventHandler(textBox1_KeyPress);

void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
 e.Handled = true;
}

ReadOnly property always greyed the control out. This is default behaviour.

what you can do to a read-only textbox is (first change it to read/write) you can override the KeyPress() event of the said TextBox and ignore all the inputs from there onwards.

This should help you:

textBox1.BackColor = Color.FromKnownColor(KnownColor.Control);
textBox1.ForeColor = Color.Red;
textBox1.ReadOnly = true;

Use a RichTextBox. When it is read only, it continue displaying the text in the color
