C# Removing Submenu Item Image Margins

Question

See the linked screenshot below.

In short, I need those little white boxes to disappear - they're supposed to house an image, but there is no image, and so I'd rather they disappear.

I've accomplished this using the follow code:

foreach (ToolStripMenuItem menuItem in mnuMain.Items)
   ((ToolStripDropDownMenu)menuItem.DropDown).ShowImageMargin = false;

This works for what I guess are the main items, but not the sub-items, as you can see in the picture.

I've tried a few variations on the above code to try and get it to capture everything instead of just the first level items, but no luck.

What am I doing wrong?

You should do that for sub items too. To do so, you can use this code:

private void Form1_Load(object sender, EventArgs e)
{
    SetValuesOnSubItems(this.menuStrip1.Items.OfType<ToolStripMenuItem>().ToList());
}

private void SetValuesOnSubItems(List<ToolStripMenuItem> items)
{
    items.ForEach(item =>
            {
                var dropdown = (ToolStripDropDownMenu)item.DropDown;
                if (dropdown != null)
                {
                    dropdown.ShowImageMargin = false;
                    SetValuesOnSubItems(item.DropDownItems.OfType<ToolStripMenuItem>().ToList());
                }
            });
}
