The RadDropDownList will always show the first item, unless you speciifically set it to something else. In my view, it's not normal winforms practice to provide a blank entry as the first item that the user can deselect, and then go back to again. If you really need to have a default item, then this should be added to the datasource.
I hope this helps but let me know if you need more help.
