Get cardname along with cardcode usuing Choose From List Button

Hi,

I am using Choose From List button in my form. If I click the button then I can see the matrix containing business partners list and if I choose any business partner from that list then I can see the business partners id or cardcode from ocrd table in the corresponding textbox.

But I want the business partner's name or cardname also should come simultaneously in the next textbox of my form. Can some one provide me any code help for this process.

Regards,

Sudeshna.
