.NET ------ 省市县反向赋值

将选中的赋值到下拉框中，因为是三级联动的所以要注意调用触发下一级的方法

 首先将一个整的进行截取，分别赋值到对应的地方

        {
            string sGongSiGangWeiGuid = this.HidGongSiGangWeiGuid.Value;
            ITEM.Model.qdMis4.UGongSiGangWei mGw = _bllGongSiGangWei.GetModelSelUGongSiGangWei3("GongSi_Name,GongSi_4001_Name,GongSi_4001_Code,GongSi_Address,GongSi_Tel,GongSi_User,GangWei_Name,GangWei_Content,GangWei_UserSum", base.EnterpriseGuid,sGongSiGangWeiGuid);
            this.tbGongSi_Name.Text = mGw.GongSi_Name;
            this.tbGongSi_Tel.Text = mGw.GongSi_Tel;
            this.tbGongSi_User.Text = mGw.GongSi_User;     
            this.tbGongSi_Address.Text = mGw.GongSi_Address;
            this.tbGangWei_Name.Text = mGw.GangWei_Name;
            this.tbGangWei_Content.Text = mGw.GangWei_Content;

            this.ddlAreaSheng_GongSi_4001_Code.SelectedValue = mGw.GongSi_4001_Code.Substring(0, 18);
            ddlArea_GongSi_4001_Code_SelectedIndexChanged(ddlAreaSheng_GongSi_4001_Code, e);
            this.ddlAreaShi_GongSi_4001_Code.SelectedValue= mGw.GongSi_4001_Code.Substring(0, 27);
            ddlArea_GongSi_4001_Code_SelectedIndexChanged(ddlAreaShi_GongSi_4001_Code, e);
            this.ddlAreaXian_GongSi_4001_Code.SelectedValue= mGw.GongSi_4001_Code.Substring(0, 36);


        }

联动的方法

    protected void ddlArea_GongSi_4001_Code_SelectedIndexChanged(object sender, EventArgs e)
    {
        DropDownList ddl = (DropDownList)sender;
        if (ddl.ID == "ddlAreaSheng_GongSi_4001_Code")
        {
            ddlAreaShi_GongSi_4001_Code.Items.Clear();
            ddlAreaXian_GongSi_4001_Code.Items.Clear();
            string scode = ddl.SelectedValue;
            List<ITEM.Model.qdCnt4.FourCollsType> mList = _bllTypeColls.Get_Ex_FourCollsTypeList_CodeDown("TypeCollCode,TypeCollName", base.EnterpriseGuid, 4001, scode, 3,(float)_iFlag);
            ddlAreaShi_GongSi_4001_Code.DataTextField = "TypeCollName";
            ddlAreaShi_GongSi_4001_Code.DataValueField = "TypeCollCode";
            ddlAreaShi_GongSi_4001_Code.DataSource = mList;
            ddlAreaShi_GongSi_4001_Code.DataBind();
            ddlAreaShi_GongSi_4001_Code.Items.Insert(0, new ListItem());
        }
        else if (ddl.ID == "ddlAreaShi_GongSi_4001_Code")
        {
            ddlAreaXian_GongSi_4001_Code.Items.Clear();
            string scode = ddl.SelectedValue;
            List<ITEM.Model.qdCnt4.FourCollsType> mList = _bllTypeColls.Get_Ex_FourCollsTypeList_CodeDown("TypeCollCode,TypeCollName", base.EnterpriseGuid, 4001, scode, 4,(float)_iFlag);
            ddlAreaXian_GongSi_4001_Code.DataTextField = "TypeCollName";
            ddlAreaXian_GongSi_4001_Code.DataValueField = "TypeCollCode";
            ddlAreaXian_GongSi_4001_Code.DataSource = mList;
            ddlAreaXian_GongSi_4001_Code.DataBind();
            ddlAreaXian_GongSi_4001_Code.Items.Insert(0, new ListItem());
        }
    }

保存的时候省市县追加到一块

        if (this.ddlAreaXian_GongSi_4001_Code.SelectedValue == string.Empty)
        {
            uXueShengJiuYe.GongSi_4001_Code = string.Empty;
            uXueShengJiuYe.GongSi_4001_Name = string.Empty;
          
        }
        else
        {
            uXueShengJiuYe.GongSi_4001_Code = this.ddlAreaXian_GongSi_4001_Code.SelectedValue;

            uXueShengJiuYe.GongSi_4001_Name = this.ddlAreaSheng_GongSi_4001_Code.SelectedItem.Text.Replace("┊", "").Replace("┈", "") + "/" + this.ddlAreaShi_GongSi_4001_Code.SelectedItem.Text.Replace("┊", "").Replace("┈", "") + "/" + this.ddlAreaXian_GongSi_4001_Code.SelectedItem.Text.Replace("┊", "").Replace("┈", "");
        }
