You'll have to use the old TrackPopupMenu or TrackPopupMenuEx API calls for
that. You can use menu.show(...) to show a menu at a specific position, but
as you have found, you cannot align the menu or get the size of the menu
before calling it.

I don't want to position the context menu to the right of the button I
want to align it. I want both right hand sides to be in line with each other.
Part of my problem is I am unable to retrieve the width of the context
menu.
<an*******@discussions.microsoft.com> wrote in message
news:a0****************************@phx.gbl... Use the following code in the click event of the button:
System.Drawing.Point pos = new System.Drawing.Point
(yourButton.Width + 10, 0);
this.contextMenu1.Show(this.yourButton, pos);
This will show the context menu 10 pixels to right of the
button. You can set the height appropriately. The code
above aligns the top of the menu with the top of the
button.
Thanks

This is very simple and for the life of me the solution
escapes me.
How can I align a context menu to the right button of a
button?
