fetching more than one row from a table after selecting one value from the dropdown

Hi Experts,

How can we fetch more than one row from a table after selecting one value from the dropdown.

The scenario is that I have some entries in the dropdown like below

  A               B               C        

11256          VID          911256  

11256          VID          811256

11256          SONY      11256

The 'B' values are there in the dropdown. I have removed the duplicate entries from the dropdown so now the dropdownlist has only two values.for eg- 'VID' and'SONY'. So now, after selecting 'VID' from the dropdown I should get all the 'C' values. After this the "C' values are to be passed to other methods to fetch some data from other tables.

Request your help on this.

Thanks,

Preeetam Narkhede.
