MenuItem.PerformSelect Method
Assembly: System.Windows.Forms (in system.windows.forms.dll)
In this example you programmatically select a menu item by using the PerformSelect method. First, you create a main menu (mainMenu1) and add to it two menu items, menuItem1 (File) and menuItem2 (Edit). You also use the Select event to send data to the event handler when a menu item is selected. Then you use the PerformSelect method to select the File menu item. When you start the application, the File menu item is selected, and a message box that contains the text "The File menu is selected." appears on the screen. The example requires that you have created a Form named Form1.
public void CreateMyMenu() { // Create a main menu object. MainMenu mainMenu1 = new MainMenu(); // Create empty menu item objects. MenuItem menuItem1 = new MenuItem(); MenuItem menuItem2 = new MenuItem(); // Set the caption of the menu items. menuItem1.Text = "&File"; menuItem2.Text = "&Edit"; // Add the menu items to the main menu. mainMenu1.MenuItems.Add(menuItem1); mainMenu1.MenuItems.Add(menuItem2); // Add functionality to the menu items. menuItem1.Select += new System.EventHandler(this.menuItem1_Select); menuItem2.Select += new System.EventHandler(this.menuItem2_Select); // Assign mainMenu1 to the form. this.Menu=mainMenu1; // Select the File menu item. menuItem1.PerformSelect(); } private void menuItem1_Select(object sender, System.EventArgs e) { MessageBox.Show("You selected the File menu.","The Event Information"); } private void menuItem2_Select(object sender, System.EventArgs e) { MessageBox.Show("You selected the Edit menu.","The Event Information"); }

public void CreateMyMenu()
{
// Create a main menu object.
MainMenu mainMenu1 = new MainMenu();
// Create empty menu item objects.
MenuItem menuItem1 = new MenuItem();
MenuItem menuItem2 = new MenuItem();
// Set the caption of the menu items.
menuItem1.set_Text("&File");
menuItem2.set_Text("&Edit");
// Add the menu items to the main menu.
mainMenu1.get_MenuItems().Add(menuItem1);
mainMenu1.get_MenuItems().Add(menuItem2);
// Add functionality to the menu items.
menuItem1.add_Select(new System.EventHandler(this.menuItem1_Select));
menuItem2.add_Select(new System.EventHandler(this.menuItem2_Select));
// Assign mainMenu1 to the form.
this.set_Menu(mainMenu1);
// Select the File menu item.
menuItem1.PerformSelect();
} //CreateMyMenu
private void menuItem1_Select(Object sender, System.EventArgs e)
{
MessageBox.Show("You selected the File menu.", "The Event Information");
} //menuItem1_Select
private void menuItem2_Select(Object sender, System.EventArgs e)
{
MessageBox.Show("You selected the Edit menu.", "The Event Information");
} //menuItem2_Select
