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> </text>
}
<br />
<br /> <input type="submit" value="Submit" />
}
