Question

我有两个文本框和一个下拉列表。我已经通过Ajax.BeginForm（）方法使用它们的id将textboxes的值传递给controller action方法。但是如何传递dropdownlist的值，因为它没有由id定义。这是我的代码：

DeliveryIndex.cshtml：

height: 50px

控制器：

@using (Ajax.BeginForm("CustomerFilter", "Delivery", new System.Web.Mvc.Ajax.AjaxOptions
{
    InsertionMode = System.Web.Mvc.Ajax.InsertionMode.Replace,
    HttpMethod = "POST",
    UpdateTargetId = "deliverylist"
 }))
{               
<input id="from" name="from" type="text" />

<input id="to" name="to" type="text" />

@Html.DropDownList("CUS_NAME",null,"--Select Customer--",new { @Style = "WIDTH:169PX" })

<input type="submit" value="View" id="BtnSubmit" />
}

Answer 1

根据您的示例，参数应该可以CUS_NAME。

将您的操作更改为：

[HttpPost]
public ActionResult CustomerFilter(string from, string to, string CUS_NAME)
{     
....   
}

将通过它，但我会建议使用强类型视图模型。

举个例子：

查看模型

public class FooViewModel
{
  public string From { get;set; }
  public string To { get;set; }
  // represents the selected value
  public string CusName { get;set; }
  public List<Customer> AvailableCustomers { get;set;}
}

public class Customer 
{
  public int Id { get;set;}
  public string Name { get;set;}
}

<强>动作

[HttpPost]
public ActionResult CustomerFilter(FooViewModel model)
{     
 ....   
}

查看

@model FooViewModel @using (Ajax.BeginForm("CustomerFilter", "Delivery", new System.Web.Mvc.Ajax.AjaxOptions { InsertionMode = System.Web.Mvc.Ajax.InsertionMode.Replace, HttpMethod = "POST", UpdateTargetId = "deliverylist" })) { @Html.TextBoxFor(m => m.From) @Html.TextBoxFor(m => m.To) @Html.DropDownListFor(m => m.CusName, new SelectList(model.AvailableCustomers, "Id", "Name"),"--Select Customer--",new { @Style = "WIDTH:169PX" }) <input type="submit" value="View" id="BtnSubmit" /> }

<强>更新根据Stephen Muecke的评论，我已经更新了模型以包含一系列选项。
