for example i have three company microsoft, oracle and apple for column a , now for column b for micrsoft i have ms office , windows and sqlserver, for oracle oracle server,oracle dbms and oracle report server and for apple applesoftware, apple textpad and apple games.... for ms office in column c i have ms access , ms doc, and ms excel.
take a look at previous pic... i selected column b and c in different rows while there column a is not selected.... so how they are dependent in that row....
I know its difficult to understand by reading.... So i think posting a pic help you.... Take a look i can select data in multiple row, while i want to make dependent combo box , b depend on a and c on b.... but here i can select data freely. i want to restrict user to select data according to a combo box in that row ....
There are three combo boxes... a . b and c .... i have attached them with with jtable. now there are choices in a combo box on which items are dependted on b combo box , e.g for choice "one" in a , b combo box contain 1,2,3. Problem is when if i select any choice in a combo box, the b combo box getitems not only in the row in which i m working but also in all table rows....
Its because i m trying hard to get the logic.... I havent got a single answer yet which has explained things very clear......I just want a single explained answer.... :-(
