Transparent Popup for winforms

I'm trying to show a popup when clicking on a cell in a grid. The popup has a usercontrol which contains an Element Host. I'm trying to make the popup transparent so I can see whats on the grid beneath but it doesn't seem to work. I'm using a ToolStripDropDown to show the popup.

Here is my code for the popup

ToolStripDropDown popup = new ToolStripDropDown();
popup.BackColor = Color.Transparent;
UserControl2 userControl = new UserControl2(popup);
userControl.Show();
popup.Margin = Padding.Empty;
popup.Padding = Padding.Empty;
ToolStripControlHost host = new ToolStripControlHost(userControl);
host.BackColor = Color.Transparent;
host.Margin = Padding.Empty;
host.Padding = Padding.Empty;
popup.Items.Add(host);

and here is the code for the UserControl itself

public partial class UserControl2 : UserControl
{
    private ToolStripDropDown popup;
    public UserControl2(ToolStripDropDown toolStrip)
    {
        InitializeComponent();
        SetStyle(ControlStyles.SupportsTransparentBackColor, true);
        this.BackColor = Color.Transparent;
        popup = toolStrip;

        this.elementHost1.BackColorTransparent = true;
    }
}

and this is the resultenter image description here

Can someone tell what I'm doing wrong here, is there any way to show a transparent popup. The popup will eventually host a transparent WPF Control.

Thanks.
