MenuItem::PerformClick Method ()
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
You can use this menu to activate a menu item through code without passing any event information. For example, if you want to activate a menu item based on an action that occurs in your application, you can call the PerformClick method for that MenuItem.
In this example you programmatically click a menu item by using the PerformClick method. First, you create a main menu (mainMenu1) and add to it two menu items, menuItem1 (File) and menuItem2 (Edit). You also use the Click event to send data to the event handler when a menu item is clicked. Then you use the PerformClick method to click the File menu item. When you start the application, the File menu item is activated, and a message box that contains the text "The File menu is clicked." 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 = gcnew MainMenu; // Create empty menu item objects. MenuItem^ menuItem1 = gcnew MenuItem; MenuItem^ menuItem2 = gcnew 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->Click += gcnew System::EventHandler( this, &Form1::menuItem1_Click ); menuItem2->Click += gcnew System::EventHandler( this, &Form1::menuItem2_Click ); // Assign mainMenu1 to the form. this->Menu = mainMenu1; // Perform a click on the File menu item. menuItem1->PerformClick(); } private: void menuItem1_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ ) { MessageBox::Show( "You clicked the File menu.", "The Event Information" ); } void menuItem2_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ ) { MessageBox::Show( "You clicked the Edit menu.", "The Event Information" ); }
