LIstbox in MVC 2
I am having a Employee Table. From that i want to load the Employee Nam开发者_开发知识库es in a List Box. I dont know from where i should start. Kindly guide me.
As always start by defining the view model that will represent your data:
public class Employee
{
public string Id { get; set; }
public string Name { get; set; }
}
public class MyViewModel
{
public string SelectedEmployeeId { get; set; }
public IEnumerable<Employee> Employees { get; set; }
}
Then the controller which will manipulate the model:
public class HomeController : Controller
{
public ActionResult Index()
{
var model = new MyViewModel
{
// TODO: Instead of hardcoding fetch from your repository
Employees = Enumerable.Range(1, 5).Select(i => new Employee
{
Id = i.ToString(),
Name = "employee " + i
})
};
return View(model);
}
}
And finally generate a dropdown list in the view:
<%: Html.DropDownListFor(
x => x.SelectedEmployeeId,
new SelectList(Model.Employees, "Id", "Name")
) %>
If you want to allow multiple selections a.k.a ListBox a few changes are necessary. First you need an array of employee ids in your model:
public class MyViewModel
{
public string[] SelectedEmployeeIds { get; set; }
public IEnumerable<Employee> Employees { get; set; }
}
And then use the ListBoxFor
helper in the view:
<%: Html.ListBoxFor(
x => x.SelectedEmployeeIds,
new SelectList(Model.Employees, "Id", "Name")
) %>
you could also try my AjaxDropdown helper and populate your listbox via jquery Ajax (you don't have to know anything about jquery)
