How can i delete or remove a specific index of row from dropdown
答
在DropDownList的ListItemCollection上调用RemoveAt:

Call RemoveAt on the ListItemCollection of the DropDownList:
http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.listitemcollection.removeat.aspx[^]
e.g.
var index = 3;
dropDownList1.Items.RemoveAt(index);
