标题: 下拉列表选中项改变form表单控件
前端页面：
F.Panel().ShowBorder(false).ShowHeader(false).ID("panelTop").Layout(LayoutType.HBox).Items(
                              F.DropDownList().ID("PointSelect").DataTextField("Value").DataValueField("Key").Width(120).DataSource(ViewBag.ddlPoint),
                              F.DropDownList().ID("Record").Required(true).DataTextField("Value").DataValueField("Key").AutoSelectFirstItem(false).EmptyText("点击选择记载项")
                              .OnSelectedIndexChanged(Url.Action("DoSearchPaging"), "DataEnterGrid", new Parameter("Layout_detailId", "F.ui.Layout_detailId.getText().replace(/<[^>]+>/g, '')"),new Parameter("recordId", "F.ui.Record.getValue()"))
                              .Width(150).MarginLeft(5).DataSource(ViewBag.recordName),
                              F.Form().ID("diffInputForm").Width(150).MarginLeft(5).Layout(LayoutType.Fit).ShowBorder(false).ShowHeader(false).Items(ViewBag.DiffInput),

Controller：
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult DoSearchPaging(FormCollection values, long? Layout_detailId, long? recordId)
      {
         DoPageRefresh(values, Layout_detailId, recordId);
         return UIHelper.Result();
      }

public void DoPageRefresh(FormCollection values, long? Layout_detailId, long? recordId)
      {
   Pager pagerDatas = new Pager(values.GetFineUIGridPageIndex("DataEnterGrid") + 1, AppSettingsUtility.DefaultGridPageSize);
            var datasDatas = bll.GetListByPager<R_recordvalueEntity>(pagerDatas, a => a.RecordId == recordId && a.LayoutDetailId ==             Layout_detailId, PagerSortDirection.ASC, w => w.Id)
                                          .Select(b => new { b.Id, b.Point, b.Value, b.RecordId, b.EnterDate, b.Images, b.Comments }).ToList();
            List<FormInfoMode2> Form2 = new List<FormInfoMode2>();
            for (var i = 0; i < datasDatas.Count(); i++)
            {
                  FormInfoMode2 Form = new FormInfoMode2();
                  Form.Id = datasDatas.Id;
                  Form.Point = datasDatas.Point;
                  Form.Value = datasDatas.Value;
                  Form.RecordId = datasDatas.RecordId;
                  Form.EnterDate = datasDatas.EnterDate;
                  Form.Images = datasDatas.Images;
                  Form.Comments = datasDatas.Comments;
                  Form.RecordName = bll.GetEntity<R_recordEntity>(w => w.id == datasDatas.RecordId).record_name;
                  Form2.Add(Form);
            }
            var gridDatas = UIHelper.Grid("DataEnterGrid");
            gridDatas.RecordCount(pagerDatas.RecordCount);
            gridDatas.DataSource(Form2, values.GetFineUIGridFields("DataEnterGrid"));
            //根据记载项类型添加不同的数据录入框
            ViewBag.DiffInput = ChooseDiffTypeInput(recordId);
}
怎么才能给返回去？

ViewBag只能页面初始化时使用，ViewBag表示的是从Controller到View的数据传递。

如果只有数字输入框和文本输入框等几个有限的控件切换，可以用显示隐藏的方式最简单
