MVC RadioButton

本文介绍如何创建radiobutton.

Step 1: 创建一个类用于获取所有的选项。

public class Company
    {
        public string SelectedDepartment { get; set; }

        public List<Department> Departments
        {
            get
            {
                SampleDataContext db = new SampleDataContext();
                return db.Departments.ToList();
            }
        }
    }

Step 2: 在controller文件里写入httpget and httppost方法。

[HttpGet]
public ActionResult Index()
{
    Company company = new Company();
    return View(company);
}

[HttpPost]
public string Index(Company company)
{
    if (string.IsNullOrEmpty(company.SelectedDepartment))
    {
        return "You didn't select any department.";
    }
    else
    {
        return "You selected department with ID = " + company.SelectedDepartment;
    }
}

Step 3: 在view里显示radiobutton

@using (Html.BeginForm())
{
    foreach (var department in Model.Departments)
    {
        @Html.RadioButtonFor(m => m.SelectedDepartment, department.DepartmentID,
        (department.IsSelected.HasValue && department.IsSelected.Value) ? new {@checked = "checked"} : null) @department.Name <text>&nbsp;</text>
    }
    <br />
    <br />
    
    <input type="submit" value="Submit" />
}
