How To Map A Combo Box Value To It's Index

I have DataSet "ds", that has a table with two columns and 11 rows. First columns is "ID" second column "name". I need to fill a combo box, with all teh names in "name" column. This i can do with

foreach(DataRow d as ds.Tables[0].Rows){ cmbBox.Items.add(d.ToString());}

But i need to map each name in the combo box to it's "ID" (in the table). Assume ID = 10000 has the name = "Mark", then if the user selects "Mark", i can store it's "ID" 1000 to a variable. How do i map the "ID" to "Name"?PS: Appologies for C# code !
