MDIWindowListITem Not Working

This one has really got me stumped. I have certain forms that are being instantiated. When I instantiate a form i make it a child of the mdi form by

form1.MdiParent = this;

I have set the MDIWindowListITem property of my menustrip to a toolstripmenuitem

However this toolstripmenuitem does not show the mdi child form when it is instantiated

Does any one have any ideas on this?

Any inputs/ leads / hints would be most welcome. I am using .net framework 3.5

Regards

You have to write your code so that it is added manually I believe.

See the example here for pointers:

MSDN help on ToolStripPanel

Edit

You're right ignore my previous entry here's the code for a very simple MDI app that appears to do what your after.

It is just two blank forms. Form1 has IsMDIContainer=true. It also has menuStrip1, which contains two items "new" (newToolStripMenuItem) and "windows" (windowsToolStripMenuItem). Clicking new will open a new child window. I have set the MDIWindowListItem of menuStrip1 to windowsMenuStripItem. When a new child window is opened clicking on windowsMenuStripItem produces a drop down that shows all windows open.

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        private int count;
        public Form1()
        {
            InitializeComponent();
        }

        private void newToolStripMenuItem_Click(object sender, EventArgs e)
        {
            count++;
            //Set a window title text as this is what is shown in the window list.
            Form2 newForm = new Form2() { Text = string.Format("Window {0}", count) };
            newForm.MdiParent = this;
            newForm.Show();//<--- this needed to show window in list.
        }
    }
}

There is no code in Form2.

The child windows only show below windowMenuStripItem once Form.Show() has been called. Without this they do not show in the list.
