Namespace: System.Windows.Forms

Not applicable.

ToolStripContainer is similar to SplitContainer. It uses four docked side panels (instances of ToolStripPanel) and one central panel (an instance of ToolStripContentPanel) to create a typical arrangement. You cannot remove the side panels, but you can hide them by setting their respective TopToolStripPanelVisible, BottomToolStripPanelVisible, LeftToolStripPanelVisible, and RightToolStripPanelVisible properties to false. By default, each of these properties is true at design time. Also at design time, the ToolStripContainer appears with its top panel already expanded. You can neither remove nor hide the ToolStripContentPanel. You can arrange one or more ToolStrip, MenuStrip, or StatusStrip controls in the side panels, and you can use the central panel for other controls. The ToolStripContentPanel also provides a way to get renderer support into the body of your form for a consistent appearance.

ToolStripContainer does not support Multiple Document Interface (MDI) applications. Use ToolStripPanel for MDI applications.

The following code example demonstrates adding a ToolStripContainer and a ToolStrip to a Windows Forms, adding items to the ToolStrip, and adding the ToolStrip to the TopToolStripPanel of the ToolStripContainer.

using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

public class Form1 : Form
    private ToolStripContainer toolStripContainer1;
    private ToolStrip toolStrip1;

    public Form1()
    static void Main()
        Application.Run(new Form1());

    private void InitializeComponent()
        toolStripContainer1 = new System.Windows.Forms.ToolStripContainer();
        toolStrip1 = new System.Windows.Forms.ToolStrip();
        // Add items to the ToolStrip.
        // Add the ToolStrip to the top panel of the ToolStripContainer.
        // Add the ToolStripContainer to the form.
