ContextMenuStrip drawn improperly above specified Control

Question

I am trying to create a specialized toolbar for my application, it consists of a few buttons which when clicked should show a ContextMenuStrip above them with a few choices. It seems that I cannot get this menu to be drawn in the proper position.

Below is a SSCCE that reproduces the problem and here are a few pictures showing the problem.

Any ideas on how to fix this?

Answer 1

Ahh, it seems my knowledge of English has led me astray.

Positions the ToolStripDropDown relative to the specified control at the specified location and with the specified direction relative to the parent control. (Inherited from ToolStripDropDown.)

This:

contextMenuStrip1.Show(fromControl, fromControl.Location, ToolStripDropDownDirection.AboveRight);

Should be this:

Point origin = new Point(0, 0);
contextMenuStrip1.Show(fromControl, origin, ToolStripDropDownDirection.AboveRight);
