sorry i've made a mistake
the FindByText method belongs to ListItemCollect ion class, so the code should be

subject.Items.F indByText("C++" )...

try this

DropDownList1.S electedIndex = DropDownList1.I tems.IndexOf(Dr opDownList1.Ite ms.FindByValue( <value>))
'DropDownList1. SelectedIndex = DropDownList1.I tems.IndexOf(Dr opDownList1.Ite ms.FindByText(< Text>))
