MVC Dropdownlist数据绑定 默认值
@Html.DropDownList("Data", (SelectList)ViewBag.Data, new { @class = "form-control chosen-select-disable_search", data_placeholder = "请选择..." })
List Data= new List(); Data.Add(new SelectListItem { Text = "AA", Value = "1" }); Data.Add(new SelectListItem { Text = "BB", Value = "2", Selected = true }); ViewBag.Data= Data;
按照上面的代码给Dropdownlist数据源设置了默认值,但实际上预览的时候并没有绑定默认值。后来研究发现,ViewBag的参数名和Dropdownlist的name不能重名
将cshtml中的代码改为下面这样既可。
@Html.DropDownList("Data1", (SelectList)ViewBag.Data, new { @class = "form-control chosen-select-disable_search", data_placeholder = "请选择..." })
