FontDialog

This Windows Forms control presents a font selection dialog box. With it, we can quickly give users the ability to select their favorite fonts.

We often use FontDialog with DialogResult. You can check the DialogResult returned by ShowDialog for the DialogResult.OK value.

First, add a FontDialog instance, and also a Button and a TextBox to an empty Windows Form. Then, double-click on the Button to insert the button1_Click event handler.

using System;
using System.Drawing;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            // Show the dialog.
            DialogResult result = fontDialog1.ShowDialog();
            // See if OK was pressed.
            if (result == DialogResult.OK)
            {
                // Get Font.
                Font font = fontDialog1.Font;
                // Set TextBox properties.
                this.textBox1.Text = string.Format("Font: {0}", font.Name);
                this.textBox1.Font = font;
            }
        }
    }
}

FixedPitchOnly

What does the FixedPitchOnly property on the FontDialog do? This changes the list of fonts in the dialog so that only the monospace ("fixed") ones are shown.

ShowColor

You can also change the ShowColor property to true—this adds a small color chooser to the FontDialog. Another option you have is the ColorDialog control, which offers more options.

The FontDialog control provides a complete font chooser. Because the dialog is built into Windows, its appearance may change depending on the version of Windows.
