This tip provides an example in which the content area of a single document interface application is switched between two or more UserControls.


This tip was created in response to a question in Quick Answers.

Using the code

The code contains a parent Form, containing a ToolStripContainer. The tool strip contains two buttons, used to switch between user controls. The user controls are added/removed to the container's Content property in response to button presses.

using System.Windows.Forms;

namespace RedCell.App.Example.UserControls
    /// <summary>
    /// The application's main form.
    /// </summary>
    public partial class MainForm : Form
        private readonly UserControl _christmasCarolControl;
        private readonly UserControl _greatExpectationsControl;

        /// <summary>
        /// Initializes a new instance of the <see cref="MainForm"> class.
        /// </see></summary>
        public MainForm()

            // Create a single instance of each child control.
            _christmasCarolControl = new ChristmasCarol {Dock = DockStyle.Fill};
            _greatExpectationsControl = new GreatExpectations { Dock = DockStyle.Fill };

        private void GreatExpectationsButton_Click(object sender, System.EventArgs e)

        private void ChristmasCarolButton_Click(object sender, System.EventArgs e)
