Q: dropdown list, no selected value

I am populating dropdown list with binding dataset, and dropdown list shows
first item by default when application is launched, is there any way I can
set it be empty and let user select one?

You have a choice of adding an empty row to either ddl itself or to the
bound dataset.

Call this in Page_Load(or some other handler):
ListItem li = new ListItem("-1", "");
myDDL.Items.InsertAt(0, li);
