Solution 3

ListItem itemToRemove = myDropDown.Items.FindByValue("value");
if (itemToRemove != null)
{
    myDropDown.Items.Remove(itemToRemove);
}
Or if you know the index of the item to remove, use RemoveAt method :

myDropDown.Items.RemoveAt(0);

You are "answering" your own question and tell to yourself "very nice". It it cheating or what?
