Menu.MenuItemCollection.Add Method (String, EventHandler)

.NET Framework 1.1

Adds a new MenuItem to the end of the current menu with a specified caption and a specified event handler for the Click event.

[Visual Basic]
Overloads Public Overridable Function Add( _
   ByVal caption As String, _
   ByVal onClick As EventHandler _
) As MenuItem
[C#]
public virtual MenuItem Add(
 string caption,
 EventHandler onClick
);
[C++]
public: virtual MenuItem* Add(
 String* caption,
 EventHandler* onClick
);
[JScript]
public function Add(
   caption : String,
 onClick : EventHandler
) : MenuItem;

Parameters

caption
The caption of the menu item.
onClick
An EventHandler that represents the event handler that is called when the item is clicked by the user or when a user, presses an accelerator or shortcut key for the menu item.

Return Value

A MenuItem that represents the menu item being added to the collection.

Remarks

A MenuItem can only be contained in one menu at a time, and cannot be added more than once to the same menu. To reuse a MenuItem in more than one menu, use the CloneMenu method of the MenuItem class. To remove a MenuItem that you have previously added, use the Remove method.

This version of the Add method allows you to specify a caption for the menu item and a delegate to handle the Click event. You can use this version of the Add method if your application already has an event handler to handle the Click event.

Note   The Click event is not raised for a MenuItem that contains submenu items.

Example

[Visual Basic, C#, C++] The following example uses the derived class MainMenu to create a main menu, mainMenu1, that has two MenuItem objects added to its MenuItems collection. The code uses this version of the Add method to define an event handler for the Click event of the second menu item added to the collection. The code then assigns mainMenu1 to the Menu property of the Form. This example assumes that the code defined in this example is located within a form.

[Visual Basic] 
Private Sub InitializeMyMainMenu()
    ' Create the MainMenu.
    Dim mainMenu1 As New MainMenu()
       
    ' Use the MenuItems property to call the Add method
    ' to add two new MenuItem objects to the MainMenu. 
    mainMenu1.MenuItems.Add("&File")
    mainMenu1.MenuItems.Add("&Edit", _
       New EventHandler(AddressOf menuItem2_Click))
       
    ' Assign mainMenu1 to the form.
    Me.Menu = mainMenu1
End Sub    
   
Protected Sub menuItem2_Click(sender As System.Object, e As System.EventArgs)
    ' Insert code to handle Click event.
End Sub


[C#] 
private void InitializeMyMainMenu()
{
   // Create the MainMenu.
   MainMenu mainMenu1 = new MainMenu();
   
   /* Use the MenuItems property to call the Add method
      to add two new MenuItem objects to the MainMenu. */
   mainMenu1.MenuItems.Add ("&File");
   mainMenu1.MenuItems.Add ("&Edit", new EventHandler (menuItem2_Click));

   // Assign mainMenu1 to the form.
   this.Menu = mainMenu1;
}

protected void menuItem2_Click(System.Object sender, System.EventArgs e)
{
   // Insert code to handle Click event.
}


[C++] 
private:
 void InitializeMyMainMenu()
 {
    // Create the MainMenu.
    MainMenu* mainMenu1 = new MainMenu();
    
    /* Use the MenuItems property to call the Add method
       to add two new MenuItem objects to the MainMenu. */
    mainMenu1->MenuItems->Add (S"&File");
    mainMenu1->MenuItems->Add (S"&Edit", new EventHandler (this, &Form1::menuItem2_Click));
 
    // Assign mainMenu1 to the form.
    this->Menu = mainMenu1;
 }
 
protected:
 void menuItem2_Click(System::Object* /*sender*/, System::EventArgs* /*e*/)
 {
    // Insert code to handle Click event.
 }
