关于mvc @Html.DropDownList绑定问题

[Nemo_XP]

绑定代码和效果如图.


我想让下拉框一列的选中值是从数据库循环取出来的,而不是默认的请选择,请问该怎么处理

这里面只是说怎么绑定的, 我是想在循环绑定dropdownlist数据的时候,再给这个下拉框赋一个model属性的值.

解决了. 启发网页:https://q.cnblogs.com/q/73902/ 解决思路:在每个循环中创建下拉框数据源 代码: Controller IList<GoodsQuestionTypeModel> listData = goodsQuestionManageService.GetQuestionTypeList(); listData.Insert(0, new GoodsQuestionTypeModel() { GoodsQuestionTypeId = 0, TypeName = "请选择" }); //SelectList typeData = new SelectList(listData, "GoodsQuestionTypeId", "TypeName"); //ViewBag.GoodsQuestionTypeData = typeData; ViewBag.TypeList = listData; view: foreach (var entity in Model) { SelectList typeData = new SelectList(ViewBag.TypeList, "GoodsQuestionTypeId", "TypeName",entity.GoodsQuestionTypeId); <td>@Html.DropDownList("GoodsQuestionTypeId", typeData, new { @class = "form-control input-sm" })</td> }

感谢二楼的热心.另外谁有办法在循环绑定的时候就能赋值,而不是通过循环修改数据源的处理,麻烦私密我.谢了.
