This article is created for making multiple colored texts in a textbox. By using the SelectionText property in richtextbox we have created a sample application for multiple colored texts in Microsoft’s richtextbox control. Let us see how to make it in below code.
Font font = new Font("Tahoma", 8, FontStyle.Regular);
richTextBox1.SelectionFont = font;
richTextBox1.SelectionColor = Color.Red;
richTextBox1.SelectedText = Environment.NewLine + textBox1.Text;
By using the above code, we can make a multiple colored texts in our richtextbox. This is basically used for doing some chat application. We will have to show the other end of person’s text in different color in chat application. So that we can use this method. And we can create a simple method and calling in every time of showing the text in richtextbox with the parameters of like “textbox1.text, color,..etc”.
