Answer 4

if (e.Item.ItemType == ListItemType.Item||e.Item.ItemType==ListItemType.AlternatingItem||e.Item.ItemType==ListItemType.EditItem)
        {
            DropDownList myDrop = e.Item.FindControl("drpList") as DropDownList;
       }
protected void myDrop_SelectedIndexChanged(object sender,EventArgs e)
    {
        Response.Write(((DropDownList)sender).SelectedIndex.ToString());
    }
