I am trying to connect 2 field. example In particular list.
There are 2 column (Car and model).
Car --> Audi, BMW, Mercedes Model --> Audi A3, Audi A5, BMW X3, BMW X5, Mercedes c250, Mercedes c300
lets say user select Audi in Car then in model list should only display Audi A3, Audi A5 in list box.
Your advice will be highly appreciated.
