            MainMenu mainMenu = new MainMenu();
            MenuItem fileMenuItem = new MenuItem();
            System.EventHandler temp = new System.EventHandler(fileNewMenuItem_Click);
            fileMenuItem = new MenuItem("&New", temp);
             mainMenu.MenuItems.Add(fileMenuItem);
            this.Menu = mainMenu;

 private void fileNewMenuItem_Click(Object sender, EventArgs e)
        {
            MessageBox.Show("You clicked the File -- New menu.", "The Event Information");
        }

Hi,
  How can I add a menu eent handler dynamically.I want to read the function name as a string from the table.
  this means the function name is going to be a string and so the arguments.

instead of:
System.EventHandler temp = new System.EventHandler(fileNewMenuItem_Click);

try:
fileNewMenuItem.Click += new System.EventHandler(fileNewMenuItem_Click);


check out the code that Visual Studio creates for you.

This should work:

  {
    string temp = "fileNewMenuItem_Click";
    EventHandler handler = (EventHandler)Delegate.CreateDelegate(typeof(EventHandler), this, temp);

    handler(null, null);
  }

  void fileNewMenuItem_Click(object sender, EventArgs e)
  {
  }

if fileNewMenuItem_Click is a static method use,

  EventHandler handler = (EventHandler)Delegate.CreateDelegate(typeof(EventHandler), typeof(CLASS_NAME), temp);
