ListBox - Access Selected Item Fields

Hi

I am using a ListBox connected to a SqlDataSource, the datasource returns 4 fields from my table.

I know I can access the DataTextField and the DataValueField of the selected item but is there a way to access the other 2 fields in the selected item?

Assume for example that there is 4 textboxes on the webpage and once the users selects an item in the ListBox I want to display the 4 field values of the selected item in the various textboxes.

Regards
