DropDownList 绑定的俩种写法
前台界面view 视图@using (Html.BeginForm("Index", "CustomerInformation", FormMethod.Get))
{
<p>客户名称: @Html.TextBox("SearchString") <br />
风险级别: @Html.DropDownList("dow_riskLevel_C","") @Html.Hidden("dow_riskLevel")
入围情况: @Html.DropDownList("dow_finalistCase_C","") @Html.Hidden("dow_finalistCase")
客户策略: @Html.DropDownList("dow_customerStrategy_C","") @Html.Hidden("customerStrategy_C")
省份: @Html.DropDownList("dow_province_C","") @Html.Hidden("province_C")
<input type="submit" value="查找" id="selectBtn"/></p>
}
后台Controller 数据组织用 俩种方式 组织绑定
//风险级别下拉框 数据整理 去掉重复项
var dow_riskLevel_C = from dr in db.DownSet
where dr.modelName == "客户信息" && dr.modelField == "风险级别"
select dr.modelvalue;
dow_riskLevel_C = dow_riskLevel_C.Distinct();
ViewBag.dow_riskLevel_C = new SelectList(dow_riskLevel_C, "modelvalue");
//入围情况下拉框 数据整理 去掉重复项
var dow_finalistCase_C = from df in db.DownSet
where df.modelName == "客户信息" && df.modelField == "入围情况"
select df.modelvalue;
dow_finalistCase_C = dow_finalistCase_C.Distinct();
List<SelectListItem> items = new List<SelectListItem>();
foreach (var item in dow_finalistCase_C)
{
items.Add(new SelectListItem { Text = item, Value = item });
}
ViewBag.dow_finalistCase_C = items;
