MenuStrip Class

Note: This class is new in the .NET Framework version 2.0.

Provides a menu system for a form.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

[ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch)] 
[ComVisibleAttribute(true)] 
public class MenuStrip : ToolStrip
/** @attribute ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch) */ 
/** @attribute ComVisibleAttribute(true) */ 
public class MenuStrip extends ToolStrip
ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch) 
ComVisibleAttribute(true) 
public class MenuStrip extends ToolStrip

The MenuStrip control represents the container for the menu structure of a form. You can add ToolStripMenuItem objects to the MenuStrip that represent the individual menu commands in the menu structure. Each ToolStripMenuItem can be a command for your application or a parent menu for other submenu items.

MenuStrip is the container for ToolStripMenuItem, ToolStripComboBox, ToolStripSeparator, and ToolStripTextBox objects.

Although MenuStrip replaces and adds functionality to the MainMenu control of previous versions, MainMenu is retained for both backward compatibility and future use if you choose.

The following code example demonstrates a MenuStrip in a multiple-document interface (MDI) scenario.

// This code example demonstrates how to use ToolStripPanel
// controls with a multiple document interface (MDI).
public class Form1 : Form
{
    public Form1()
    {
        // Make the Form an MDI parent.
        this.IsMdiContainer = true;

        // Create ToolStripPanel controls.
        ToolStripPanel tspTop = new ToolStripPanel();
        ToolStripPanel tspBottom = new ToolStripPanel();
        ToolStripPanel tspLeft = new ToolStripPanel();
        ToolStripPanel tspRight = new ToolStripPanel();

        // Dock the ToolStripPanel controls to the edges of the form.
        tspTop.Dock = DockStyle.Top;
        tspBottom.Dock = DockStyle.Bottom;
        tspLeft.Dock = DockStyle.Left;
        tspRight.Dock = DockStyle.Right;

        // Create ToolStrip controls to move among the 
        // ToolStripPanel controls.

        // Create the "Top" ToolStrip control and add
        // to the corresponding ToolStripPanel.
        ToolStrip tsTop = new ToolStrip();
        tsTop.Items.Add("Top");
        tspTop.Join(tsTop);

        // Create the "Bottom" ToolStrip control and add
        // to the corresponding ToolStripPanel.
        ToolStrip tsBottom = new ToolStrip();
        tsBottom.Items.Add("Bottom");
        tspBottom.Join(tsBottom);

        // Create the "Right" ToolStrip control and add
        // to the corresponding ToolStripPanel.
        ToolStrip tsRight = new ToolStrip();
        tsRight.Items.Add("Right");
        tspRight.Join(tsRight);

        // Create the "Left" ToolStrip control and add
        // to the corresponding ToolStripPanel.
        ToolStrip tsLeft = new ToolStrip();
        tsLeft.Items.Add("Left");
        tspLeft.Join(tsLeft);

        // Create a MenuStrip control with a new window.
        MenuStrip ms = new MenuStrip();
        ToolStripMenuItem windowMenu = new ToolStripMenuItem("Window");
        ToolStripMenuItem windowNewMenu = new ToolStripMenuItem("New", null, new EventHandler(windowNewMenu_Click));
        windowMenu.DropDownItems.Add(windowNewMenu);
        ((ToolStripDropDownMenu)(windowMenu.DropDown)).ShowImageMargin = false;
        ((ToolStripDropDownMenu)(windowMenu.DropDown)).ShowCheckMargin = true;

        // Assign the ToolStripMenuItem that displays 
        // the list of child forms.
        ms.MdiWindowListItem = windowMenu;

        // Add the window ToolStripMenuItem to the MenuStrip.
        ms.Items.Add(windowMenu);

        // Dock the MenuStrip to the top of the form.
        ms.Dock = DockStyle.Top;

        // The Form.MainMenuStrip property determines the merge target.
        this.MainMenuStrip = ms;

        // Add the ToolStripPanels to the form in reverse order.
        this.Controls.Add(tspRight);
        this.Controls.Add(tspLeft);
        this.Controls.Add(tspBottom);
        this.Controls.Add(tspTop);

        // Add the MenuStrip last.
        // This is important for correct placement in the z-order.
        this.Controls.Add(ms);
    }

    // This event handler is invoked when 
    // the "New" ToolStripMenuItem is clicked.
    // It creates a new Form and sets its MdiParent 
    // property to the main form.
    void windowNewMenu_Click(object sender, EventArgs e)
    {
        Form f = new Form();
        f.MdiParent = this;
        f.Text = "Form - " + this.MdiChildren.Length.ToString();
        f.Show();
    }
