Examples

The following code example is a simple program that applies visual styles in each of the four areas specified by the VisualStyleState values. To enable visual styles in a certain area, click the option button (also known as a radio button) that represents the area you want to enable, and click the Update VisualStyleState button to observe the changes in the window.

C#
using System;
using System.Drawing;
using System.Windows.Forms;
using System.Windows.Forms.VisualStyles;

namespace VisualStyleStateSample
{
    class Form1 : Form
    {
        Button button1 = new Button();
        RadioButton radioButton1 = new RadioButton();
        RadioButton radioButton2 = new RadioButton();
        RadioButton radioButton3 = new RadioButton();
        RadioButton radioButton4 = new RadioButton();

        public Form1()
        {
            button1.AutoSize = true;
            button1.Location = new Point(10, 10);
            button1.Text = "Update VisualStyleState";
            button1.Click += new EventHandler(button1_Click);

            radioButton1.Location = new Point(10, 50);
            radioButton1.AutoSize = true;
            radioButton1.Text = "Apply styles to client area only";

            radioButton2.Location = new Point(10, 70);
            radioButton2.AutoSize = true;
            radioButton2.Text = "Apply styles to nonclient area only";

            radioButton3.Location = new Point(10, 90);
            radioButton3.AutoSize = true;
            radioButton3.Text = "Apply styles to client and nonclient areas";

            radioButton4.Location = new Point(10, 110);
            radioButton4.AutoSize = true;
            radioButton4.Text = "Disable styles in all areas";

            this.Text = "VisualStyleState Test";
            this.Controls.AddRange(new Control[] { button1,  
                radioButton1, radioButton2, radioButton3, radioButton4});
        }

        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.Run(new Form1());
        }

        void button1_Click(object sender, EventArgs e)
        {
            if (radioButton1.Checked)
            {
                Application.VisualStyleState =
                    VisualStyleState.ClientAreaEnabled;
            }
            else if (radioButton2.Checked)
            {
                Application.VisualStyleState =
                    VisualStyleState.NonClientAreaEnabled;
            }
            else if (radioButton3.Checked)
            {
                Application.VisualStyleState =
                    VisualStyleState.ClientAndNonClientAreasEnabled;
            }
            else if (radioButton4.Checked)
            {
                Application.VisualStyleState =
                    VisualStyleState.NoneEnabled;
            }

            // Repaint the form and all child controls.
            this.Invalidate(true);
        }
    }
}
