如何从MVC动作的下拉列表中获取多个属性值？ [英] How to fetch multiple attribute value from drop down list in MVC action?

问题描述

我正在尝试使用mvc操作中的单个下拉列表获取多个属性值，但我无法通过单个下拉列表获取复杂数据。

请提供任何解决方案。

您的反馈意见将不胜感激。



我的尝试：



公共类ViewModelMain

{

public ViewModelSubfunctiona Drp {get;组; }



public List< viewmodelsubfunctiona> ListFunc {get;组; }

}



公共类ViewModelSubfunctiona

{

public int Id { get; set;}

public string Name {get; set;}

public int FuncId {get; set;}

}





[HttpGet]

公共ActionResult索引（）

{

var data = GetList（）;



ViewModelMain model = new ViewModelMain（）;

model.ListFunc = data;

返回查看（型号）;

}



[HttpPost]

公共ActionResult索引（ViewModelMain模型）

{



返回查看（）;

}



public List< ViewModelSubfunctiona> GetList（）

{

List< ViewModelSubfunctiona> _list = new List< ViewModelSubfunctiona>（）;

_list.Add（new ViewModelSubfunctiona {Id = 1，Name =A，FuncId = 1}）;

_list .Add（new ViewModelSubfunctiona {Id = 2，Name =B，FuncId = 1}）;

_list.Add（new ViewModelSubfunctiona {Id = 3，Name =C，FuncId = 1 }）;

_list.Add（new ViewModelSubfunctiona {Id = 4，Name =D，FuncId = 2}）;

_list.Add（new ViewModelSubfunctiona {Id = 5，Name =E，FuncId = 2}）;

_list.Add（new ViewModelSubfunctiona {Id = 6，Name =F，FuncId = 2}）;

返回_list;

}





查看：@model Test.Controllers.ViewModelMain

@ Html.DropDownListFor（x => x.Drp，new SelectList（Model.ListFunc，Id，Name），，new {@ maxlength =20，@ style =}）

I am trying to fetch multiple attribute value with single drop down list in mvc action but i am not able to fetch complex data with single drop down list.
Please provide any solution.
Your feedback will be appreciated.

What I have tried:

public class ViewModelMain
{
public ViewModelSubfunctiona Drp { get; set; }

public List<viewmodelsubfunctiona> ListFunc { get; set; }
}

public class ViewModelSubfunctiona
{
public int Id{get;set;}
public string Name{get;set;}
public int FuncId{get;set;}
}


[HttpGet]
public ActionResult Index()
{
var data = GetList();

ViewModelMain model = new ViewModelMain();
model.ListFunc = data;
return View(model);
}

[HttpPost]
public ActionResult Index(ViewModelMain model)
{

return View();
}

public List<ViewModelSubfunctiona> GetList()
{
List<ViewModelSubfunctiona> _list = new List<ViewModelSubfunctiona>();
_list.Add(new ViewModelSubfunctiona { Id = 1, Name = "A", FuncId = 1 });
_list.Add(new ViewModelSubfunctiona { Id =2, Name = "B", FuncId = 1 });
_list.Add(new ViewModelSubfunctiona { Id = 3, Name = "C", FuncId = 1 });
_list.Add(new ViewModelSubfunctiona { Id = 4, Name = "D", FuncId = 2 });
_list.Add(new ViewModelSubfunctiona { Id = 5, Name = "E", FuncId = 2 });
_list.Add(new ViewModelSubfunctiona { Id = 6, Name = "F", FuncId =2 });
return _list;
}


View:@model Test.Controllers.ViewModelMain
@Html.DropDownListFor(x => x.Drp, new SelectList(Model.ListFunc,"Id","Name"),"", new { @maxlength="20", @style="" })
