                if (DetailsView1.CurrentMode == DetailsViewMode.Edit)

                    ddlLast((DropDownList)DetailsView1.FindControl("sf_last"));
                    ((DropDownList)DetailsView1.FindControl("sf_last")).SelectedValue = ((Label)DetailsView1.FindControl("tmpLast")).Text;
                }

        protected void ddlLast(DropDownList myddlLast)
        {
            myddlLast.Items.Add(new ListItem("15天", "15"));
            myddlLast.Items.Add(new ListItem("30天", "30"));
            myddlLast.Items.Add(new ListItem("半年", "180"));
            myddlLast.Items.Add(new ListItem("1年", "365"));
