给下拉框写cs代码

  protected override void onl oad(EventArgs e)
    {
        base.OnLoad(e);
       Control.Click += Control_Click;
        container.DataChanged += container_DataChanged;
        Control0.Click += Control0_Click;
        string sql1 = @"select mfgordername from mfgorder";
        DataTable dt1 = CamstarHelper.GetDatatable(sql1);
        if (dt1 != null && dt1.Rows.Count > 0)
        {
            RecordSet rsNamedObject = new RecordSet();
            // 创建一个Header数组
           Header[] rsHeaders = new Header[1];
            // 创建一个Row数组
            Row[] rsRows = new Row[dt1.Rows.Count];
            // 设置Header信息
            rsHeaders[0] = new Header();
            rsHeaders[0].TypeCode = TypeCode.String;
            rsHeaders[0].Name = "Name";
            // 设置RecordSet的Header
            rsNamedObject.Headers = rsHeaders;
            // 遍历DataTable的每一行，创建Row对象并设置值
            for (int x = 0; x < dt1.Rows.Count; x++)
            {
                rsRows[x] = new Row();
                rsRows[x].Values = new string[] { dt1.Rows[x]["mfgordername"].ToString() };
            }
            // 设置RecordSet的Rows
            rsNamedObject.Rows = rsRows;
            // 调用SetSelectionValues方法设置下拉列表的值
            mfgorder.SetSelectionValues(rsNamedObject);
        }
    }
