how to change WinForm controls' text color programatically?

Hi again
You're rignt, if the textBox is readOnly it does't chage the foreColor. I have 2 solutions for you :)

1. (easy way) use label instead of "readOnly textBox" as I can see everything is same, the only diference is you can't select label;s text, and you can do that on the textBox's text...
2. (hard way) you need to write another class that inherits from System.Windows.Forms.TextBox and make some changes, and use it instead of regular textbox, like this:

class mojTextBox:System.Windows.Forms.TextBox

protected override void OnPaint(System.Windows.Forms.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

public mojTextBox()

this.SetStyle(System.Windows.Forms.ControlStyles.UserPaint, true);

//InitializeComponent();

attention, Aleksandar Ilioski:

Here's what I discovered through trial and error: it turns out that when a TextBox's ReadOnly property is set to true (as this one was), the Text property can be modified, but the ForeColor property can't. I even tried it in two different programs. It has been suggested that this sounds like a bug in .Net. I wonder if it's just a problem with my particular installation of VC# Express 2008.

Anyway, here's the form1.cs for a little test program that produces the error, at least on my computer. It's just a WinForm with one button and one TextBox.

using System;
using System.Windows.Forms;
 
namespace ChangeTextColor2
{
    public partial class TestForm : Form
    {
        public TestForm ()
        {
            InitializeComponent ();
            textBox1.Text = "This is the original text.";
        }
 
        private void btn_Click (object sender, EventArgs e)
        {
            textBox1.Text = "Now the text should be turned red.";
            textBox1.ForeColor = System.Drawing.Color.Red;
        }
    }
}

attention, Aleksander Ilioski:

Yes, I think that answers my question about how to get the compiler to recognize the color I want: by saying

this.ForeColor = System.Drawing.Color.Red

instead of

this.ForeColor = Red;

but it doesn't change the color of the text already displayed, even when I reassign the string displayed to the text field of the control. Can you tell me how to make the control redisplay the text in the new color?

this.ForeColor = System.Drawing.Color.Red;
//is this what you are lookng for?
