ToolStripMenuItem items show in the incorrect location

Question

I have a ToolStripMenuItem that contain submenus to select from. The problem is that they are displaying in the wrong place:

I have this code that I used for the submenu (this was for the ToolStripCombobox -Thank you Reza for the solution-) of the above items but I'm having a hard time tweaking in to make it work for the ToolStripMenuItem as it does not contain a Control.Parent.GetType() :

private void Form_Load(object sender, EventArgs e)
    {
        var item = toolStripComboBox;
        var createControl = item.Control.Parent.GetType().GetMethod("CreateControl",
            System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
        createControl.Invoke(item.Control.Parent, new object[] { true });

As always, any help is appreciated.

I think the root of your whole problem is your using the form load event handler instead of the form constructor. When I run the following code, the menu items are in exactly the right place when the form loads:

public Form1()
{
    InitializeComponent();
    ToolStripComboBox item1 = new ToolStripComboBox();
    item1.Items.AddRange(new object[]
    {
        "One",
        "Two",
        "Thtree"
    });
    item1.DropDownStyle = ComboBoxStyle.Simple;
    menuStrip1.Items.Add(item1);
    ToolStripMenuItem item2 = new ToolStripMenuItem();
    item2.Text = "Four";
    menuStrip1.Items.Add(item2);
}
