private void richTextBox1_KeyUp(object sender, KeyEventArgs e) { string word; FontStyle fs; if (start > -1 && end > start && e.KeyData == Keys.Space) { word = richTextBox1.Text.Substring(start+1, end - (start+1)); if (word.ToUpper().Contains("X")) { fs = FontStyle.Bold; richTextBox1.Select(start, end); richTextBox1.SelectionColor = Color.Red; richTextBox1.SelectionFont = new Font(richTextBox1.SelectionFont, fs); richTextBox1.Select(end + 1, 0); } start = end; fs = FontStyle.Regular; richTextBox1.SelectionColor = Color.Black; richTextBox1.SelectionFont = new Font(richTextBox1.SelectionFont, fs); } } private void richText1_KeyPress(object sender, KeyPressEventArgs e) { if (e.KeyChar == ' ') { if (start == -1) start = richTextBox1.TextLength; if (start >= 0 && richTextBox1.TextLength > start) end = richTextBox1.TextLength; } } This is just an example of how you can do it but you have a lot of work to do to get it to work for ALL conditions, for example you may need to track every single word position that contains an X in it, this could be done with an array of Points eg Point p = new Point(x, y); x being the start of the word, y being the end but then you would need to know about paragraphs, line number etc .....

Try like this. RichTextBox Richtxt = new RichTextBox(); Richtxt.Width = 100; Richtxt.Height = 50; Richtxt.ForeColor = Color.Green; Richtxt.Text = "RichTextBox"; Richtxt.Name = "RichTextBox"; Controls.Add(Richtxt);
