Determine if comboBox selectedIndex is changed programatically or by user?

Hey all

I have a comboBox, and I am using the selectedIndexChanged event to know when it has been changed.  I populate it with a list of choices when the user enters a row in a datagridview.  This means that the selectedIndexChanged event fires everytime the user enters a new row in the datagridview, not when the user changes the comboBox as I intended.  I would like to be able to determine when the index is changed by the user, filtering out when it's changed by the program.

I read a reply by TheLearnedOne who said the key was to handle the mouseDown and mouseUp events, but I don't know how to do this.  Could anyone post a short example?

Thanks,
