C# 页面加载后设置HtmlSelect时出现问题

我有一个C自定义控件，用于显示地址表单。在控件上，我有一个选择来选择您的状态。在pageload上，我为select设置了默认值。我有一个公开的公共方法，在这里我传递一个变量来分配所有的地址信息

我的问题是，当我运行我的方法时，选择不会更新为具有正确的选择值。有什么想法吗

下面是隐藏的代码：

    public partial class AddressFieldSet : System.Web.UI.UserControl
    {
        //Credentials
        static String EpicorWSLogin = ConfigurationManager.AppSettings["EpicorWSLogin"].ToString();
        static String EpicorWSPassword = ConfigurationManager.AppSettings["EpicorWSPassword"].ToString();
        static String EpicorWSDomain = ConfigurationManager.AppSettings["EpicorWSDomain"].ToString();
        NetworkCredential myCredentials = new NetworkCredential(EpicorWSLogin, EpicorWSPassword, EpicorWSDomain);

        private epicor_Organization.OrganizationFullDataSet.PhysicalAddressRow _Address;

        protected void Page_Load(object sender, EventArgs e)
        {
            //Load Address Data
            epicor_ValueListEntry.ValueListEntry ValueListEntryWS = new epicor_ValueListEntry.ValueListEntry();
            ValueListEntryWS.Credentials = myCredentials;

            region.DataSource = ValueListEntryWS.GetByListID(ValueListName.PhysicalAddressRegion).ValueListEntry.Select("", "Description ASC");
            region.DataTextField = "Description";
            region.DataValueField = "Entry";
            region.DataBind();

            country.DataSource = ValueListEntryWS.GetByListID(ValueListName.PhysicalAddressCountry).ValueListEntry;
            country.DataTextField = "Entry";
            country.DataValueField = "ValueListEntryID";
            country.DataBind();

            //Set some inteligent defaults for the state/country dropdown
            country.Value = Clientele.Modules.Party.Interface.Country.USA.ToString();
            region.Value = "MD";
        }

        public void Set(epicor_Organization.OrganizationFullDataSet.PhysicalAddressRow Address)
        {
            _Address = Address;

            address1.Value = Address["Address1"].ToString();
            address2.Value = Address["Address2"].ToString();
            address3.Value = Address["Address3"].ToString();
            city.Value = Address["City"].ToString();
            zip.Value = Address["PostalCode"].ToString();
            region.Value = Address["Region_"].ToString();
            country.Value = Address["CountryID"].ToString();
        }

        public epicor_Organization.OrganizationFullDataSet.PhysicalAddressRow Get()
        {
            _Address["Address1"]=address1.Value;
            _Address["Address2"]= address2.Value;
            _Address["Address3"]=address3.Value ;
            _Address["City"] = city.Value;
            _Address["PostalCode"] = zip.Value;
            _Address["Region"] = region.Value;
            _Address["CountryID"] = country.Value;

            return _Address;
        }

    }
}

从父控件，我在其Page_Load事件中调用Set函数。除“我的选择”之外的所有数据都设置正确

我的问题是无法在页面加载事件后设置select的值吗？我怎样才能避开这个问题呢？

我已经弄明白了。Page_Load事件在我的Set方法之后触发。我将Page_Load事件替换为Page_Init，一切都很好。
