Im new in sharepoint and i have something to do in sharepoint 2010.
Here is the case;
I have two multiple selection list box that is connected to each other. When i select one of the choices in multiple selection list box1 the corresponding choices appears in multiple selection listbox2 which is perfectly ok What i want to achieve is that when i unselect the choices in multiple selection listbox1 the corresponding choices in multiple selection listbox2 must be clear or remove.
I try to manipulate it in the Add Rule section but it is not succesful. Do you have any other way you can show me? Or any code ?
Thak you in advance and i would greatly appreciate your help.
