Recently I've got a question from a colleague: "Have you had a situation when somebody was trying to manipulate you  or your behavior? What can be the best way to stop/resist this sort of attitude? Stop any interaction with the person?" From my perspective manipulation, generally, has to aspects to it:

1. Other person wants you to do something (which is not necessarily a bad thing).
2. She wants to make you do it in a sort of "covert" way, which I would generally call a bad thing in professional environment.

When it comes to response to manipulation, all things being equal, I would have a conversation with a person saying something along the lines of "Hey, I've noticed that you try to trick me into something and don't like you doing that. If you need something from me, let's discuss, but don't try to trick me."

This kind of feedback serves two purposes: (a) letting other party know that you've noticed manipulation and don't like it (who does?); (b) showing a better way to do business with you. If a case is not helpless, this should help.

What do you do when somebody tries to manipulate you?
