Answer 1

myDropDown.SelectedIndex = 
    myDropDown.Items.IndexOf(myDropDown.Items.FindByValue("myValue"))

Answer 2

If you know that the dropdownlist contains the value you're looking to select, use:

ddl.SelectedValue = "2";

If you're not sure if the value exists, use (or you'll get a null reference exception):

ListItem selectedListItem = ddl.Items.FindByValue("2");

if (selectedListItem != null)
{
    selectedListItem.Selected = true;
};
