You can change the text color of the TextBox with the ForeColor property, but you can not display portions of text in a different color. You will need a RichTextBox, or something similar, for that.

To change the text color of a TextBox control:

TextBox2.ForeColor = System.Drawing.Color.Red;
TextBox2.Text += string.Format("{0}\nNot working\n\n ", link);
