我在從ASP.Net MVC窗體中獲取SelectListItem \ DropDwown選定值的值時遇到了一些困難。無法獲取SelectListItem DropDownFor選定的值
我檢查了過去的答案,並通過這些已經看過,並沒有成功
- Get selected item in DropDownList ASP.NET MVC
- Asp.Net MVC with Drop Down List, and SelectListItem Assistance
我也查了一些其他的答案太,我不能回去權現在
我的代碼在控制器中是
public ActionResult QuickSearch()
{
var ddlValues = new List<DropDownValues>
{
new DropDownValues { Text= "5", Value = 5},
new DropDownValues { Text= "10", Value = 5}
};
var model = new QuickSearchViewModel();
model.Distance = ddlValues.Select(x => new SelectListItem {Text = x.Text, Value = x.Value.ToString() });
//var model = new QuickSearchViewModel()
//{
// Distance = from value in ddlValues
// select new SelectListItem
// {
// Text = value.Text,
// Value = value.Value.ToString()
// }
//};
return PartialView(model);
}
[HttpPost]
public ActionResult QuickSearch(QuickSearchViewModel model)
{
if (ModelState.IsValid)
{
return RedirectToAction("QuickSearch", "Search", model);
}
return PartialView(model);
}
填充選擇列表的代碼工作得很好,並且觸發HttpPost事件的按鈕也按預期工作。
但是對於我的生活,除非我使用Ajax,否則我無法獲得選定的值,除非必須這樣做,否則我不想這樣做,因爲我希望這樣可以將主控制器重定向到搜索控制器。
這是局部視圖
@model SP.DABB.WebUI.Models.QuickSearchViewModel
@using(Html.BeginForm("QuickSearch", "Home", FormMethod.Post))
{
<div class="form-group">
<div class="col-md-6 col-lg-6">
@Html.LabelFor(x => x.PostCode)
</div>
<div class="col-md-6 col-lg-6">
@Html.TextBoxFor(x => x.PostCode, new { @class = "form-control" })
</div>
</div>
<div class="form-group">
<div class="col-md-6 col-lg-6">
@Html.LabelFor(m => m.Distance, new { @class = "control-label" })
</div>
<div class="col-md-6 col-lg-6">
@Html.DropDownListFor(m => m.Distance, new SelectList(Model.Distance, "Value", "Text"), new { @class = "form-control" })
@*@Html.DropDownListFor(m => m.Distance, Model.Distance, new { @class = "form-control" })*@
</div>
</div>
<br /><br />
<div class="form-group">
<div class="col-xs-12 col-sm-12 col-md-6 col-lg-6 pull-right">
@*<input type="button" id="bttnQuickSearch" class="btn btn-info pull-right" value="Perform Quick Search"/>*@
<button type="submit" id="bttnQuickSearch" class="btn btn-info pull-right">Search</button>
</div>
</div>
}
的剃刀\ HTML - 編輯 - 查看型號上架
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace SP.DABB.WebUI.Models
{
public class QuickSearchViewModel
{
[Display(Name = "Your Postcode")]
[StringLength(maximumLength:8, MinimumLength = 5, ErrorMessage = "Please provide your full postcode.")]
public string PostCode { get; set; }
[Display(Name = "Distance")]
public IEnumerable<SelectListItem> Distance { get; set; }
public int SelectedDistance { get; set; }
public QuickSearchViewModel()
{
Distance = new List<SelectListItem>();
}
}
}
任何及所有的幫助是非常讚賞。
