从ASP.Net MVC中的Dropdownlist访问值 [英] Accessing values from Dropdownlist in ASP.Net MVC

问题描述

大家好，

请帮我如何从下拉列表中访问所选值，并在Asp.net MVC中将值插入数据库



在控制器中：

Hi Guys,
please help me how to access selected value from the dropdownlist and to insert value into database in Asp.net MVC

In controller:

List<int> li = new List<int>();
            for (int i = 20; i < 50; i++)
            {
                li.Add(i);

            }
            ViewData["j"] = new SelectList(li);

在视图中

In view

<%=Html.LabelFor(Model=>Model.age) %>
                <%=Html.DropDownList("j")%>

在模型中

In model

public class details
{
[DisplayName("Age")]
        public int age { get; set; }

}

推荐答案

您始终可以从HttpPost的Request对象获取数据

例如。

You can always get the data from Request object at HttpPost
eg.

var value1 = Request["SimpleProp1"];
var value2 = Request["SimpleProp2"];
var value3 = Request["ComplexProp1.SimpleProp1"];

<![CDATA[<%=Html.DropDownList(Model=>Model.age)%>]]>

public Actionview PostAction(Model model)
{
    //selected combobox value
    int age = model.age;
}

In View You have to do something like this

@Html.DropdownListFor(Model=>Model.age,new SelectListItem{@ViewBag.j,DataFieldId,DataFieldValue},"Select Text");

i have shown you genral format,use like this. This will surely help you.
