This project is read-only.


this helper will create a list of checkboxes, you can call it like this:

<%=Html.AjaxCheckBoxList("Fruits") %>
<%=Html.AjaxCheckBoxList("Fruits", controller: "FruitsAjaxCheckBoxList") %>

it requires a controller to get it's data from, if the controller's name is not specified it will search for Prop + "AjaxCheckBoxList" (Fruits + CheckBoxList)
the controller must have an Action GetItems with a keys parameter and it should return a Json made from an IEnumerable<SelectListItem>
    public class FruitsAjaxCheckBoxListController : Controller
        public ActionResult GetItems(IEnumerable<int> keys)
            keys = keys ?? new List<int>();
            var res = repo.GetAll().Select(o =>
                                        new SelectListItem
                                                Text = o.Name,
                                                Value = o.Id.ToString(),
                                                Selected = (keys.Contains(o.Id))
            return Json(res);

you can also call it like this:
<%=Html.EditorFor(o => o.Fruits) %>

for this in your ViewModel you will need to do something like this:
[AjaxRadioList(Controller = "FruitsAjaxCheckBoxList")]
public IEnumerable<int> TheFruits { get; set; }

public IEnumerable<int> Fruits { get; set; }

just like the AjaxDropdown you can bind it with other inputs by specifying the ParentId in the attribute or in the helper's parameters
