I was trying:


 cboClass.DisplayMember = ds.Tables("Classes").Columns
("ClassNumber").ToString '& " " & ds.Tables("classes").Columns
("ClassName").ToString

OR :
        String.Format("{0}  {1}", ds.Tables("Classes").Columns
("ClassNumber").ToString, ds.Tables("Classes").Columns
("ClassName").ToString)

and what is used for the selected value??

cboclass.selectedvalue= ds.Tables("Classes").Columns("Classid")


any help
