Setting Font Attributes for the Windows Forms RichTextBox Control

The Windows Forms RichTextBox control has numerous options for formatting the text it displays. You can make the selected characters bold, underlined, or italic, using the SelectionFont property. You can also use this property to change the size and typeface of the selected characters. The SelectionColor property allows you to change the selected characters' color.

To change the appearance of characters

  • Set the SelectionFont property to an appropriate font.

    To enable users to set the font family, size, and typeface in an application, you would typically use the FontDialog component. For an overview, see Introduction to the Windows Forms FontDialog Component.

    ' Visual Basic
        RichTextBox1.SelectionFont = New Font("Tahoma", 12, FontStyle.Bold)
        RichTextBox1.SelectionColor = System.Drawing.Color.Red
        // C#
        richTextBox1.SelectionFont = new Font("Tahoma", 12, FontStyle.Bold);
        richTextBox1.SelectionColor = System.Drawing.Color.Red;
        // C++
        richTextBox1->SelectionFont =
        new System::Drawing::Font("Tahoma", 12, FontStyle::Bold);
        richTextBox1->SelectionColor = System::Drawing::Color::Red;
    Note   These properties only affect selected text, or, if no text is selected, the text that is typed at the current location of the insertion point. For information on selecting text programmatically, see TextBoxBase.Select Method.
