Refer - DropDownList.SelectedIndex Property[^], which says...

Quote:
The index of the selected item in the DropDownList control. The default value is 0, which selects the first item in the list.

The indexes for the items in the DropDownList control are zero-based.

So, both the -1 and 0 will result the same.
