For the Single-line Textbox (edit textbox uicontrol with Max=1) , all undocumented callback (FocusGainedCallback, FocusLostCallback,...) work perfectly. However, when I try with Multi-line Textbox (edit textbox uicontrol with Max=2), these callbacks have no effect. Someone know to to fix it ?

You are asking about Java object callbacks accessed using undocumented methods. Their behaviour within MATLAB is undocumented and can change from release to release and does not have to be consistent even within one release.
You could ask Yair at the above link. He might at least know the reason for the problem.
