The problem here is that DropDownList1.SelectedItem is of Type ListItem and does not immediately return the selected Value..

you have several options here ... If your looking for the DDL's selected text you can use :..
DropDownList1.SelectedItem.Text

Or if your looking for the Value behind you can use either:.
DropDownList1.SelectedItem.Value
DropDownList1.SelectedValue

NOTE : All the above returned types are string....
