How to add things to a menustrip programatically?

Answer 1

You can do this by taking advantage of the object sender parameter in the event handler. Most of this is off the top of my head so I'm only guessing that it will compile but it should get you started.

void AddMenuItem(string text, string action)
{
   ToolStripMenuItem item = new ToolStripMenuItem();
   item.Text = text;
   item.Click += new EventHandler(item_Click);
   item.Tag = action;

   //first option, inserts at the top
   //historyMenu.Items.Add(item);

   //second option, should insert at the end
   historyMenuItem.DropDownItems.Insert(historyMenuItem.DropDownItems.Count, item);
}

private void someHistoryMenuItem_Click(object sender, EventArgs e)
{
   ToolStripMenuItem menuItem = sender as ToolStripMenuItem;

   string args = menuItem.Tag.ToString();

   YourSpecialAction(args);
}

Answer 2

It's rather straight forward. You can do the following:

ToolStripMenuItem menuItem

foreach (string text in collectionOfText)
{
    ToolStripMenuItem foo = new ToolStripMenuItem(text);
    foo.Click += new EventHandler(ClickEvent);
    menuItem.DropDownItems.Add(foo);
}

Subsequently, if the Click event doesn't work (I had trouble where it wouldn't detect the correct menu item), you can add a "DropDownItemClicked" event to the menuItem. and to get the text of the item you clicked you do:

private void DropedDownItemClickedEvent(object sender, ToolStripItemClickedEventArgs e)
{
    string text = e.ClickedItem.Text;
}

I hope that helps.

Oh and don't forget to remove the Event as well. I forgot to do that with all the dynamic menus I had created and somehow ended up eating half my memory. :D
