Why when changing the text in a textBox the forecolor is black and not green?

Question

In the form1 constructor i set the textBox forecolor to be in green:

cTextBox3.WaterMarkForeColor = Color.Green;
cTextBox3.WaterMarkActiveForeColor = Color.Green;
cTextBox3.ForeColor = Color.Green;
cTextBox3.WaterMark = "Browse To The File Location";

Then i have a button click event with openFileDialog

private void button6_Click(object sender, EventArgs e)
        {
            OpenFileDialog openFileDialog1 = new OpenFileDialog();
            openFileDialog1.InitialDirectory = "c:\\";
            openFileDialog1.Filter = "Json Files (*.json)|*.json";
            openFileDialog1.FilterIndex = 0;
            openFileDialog1.RestoreDirectory = true;
            openFileDialog1.Multiselect = true;
            if (openFileDialog1.ShowDialog() == DialogResult.OK)
            {
                cTextBox3.Text = openFileDialog1.FileName;
                w = new StreamWriter(AuthenticationFileName, true);
                w.WriteLine(cTextBox3.Text);
                w.Close();
            }

        }

In the designer i set the cTextBox3 ReadOnly property to true.

The problem is once the text of the openFileDialog1.FileName is assigned to the cTextBox3.Text the text is in black. And i want it to be in green. I tried to add before the line:

cTextBox3.Text = openFileDialog1.FileName;

All the colors changes like i did in the constructor to green i tried to set the cTextBox3 ReadOnly property to false set the colors again then set it to true again and still the text is in black.

This is due to visual styles. Unless you want to disable them completely, you'll need to also set the background color, for example:

tbx.ReadOnly = true;
tbx.BackColor = Color.White;
tbx.ForeColor = Color.Green;
