MVC Html.CheckBox list and Jquery Post ?

I do not understand your comment about jQuery in previous solution comments.

If you want to receive an array (List<SomeClass>) in your control, you need to generate HTML similar to this:

<input name="MyArray[0].Role" value="MyKey" type="hidden" />

<input id="MyKey" name = "MyArray[0].Selected" type="checkbox" checked = "checked" value="true" />

<input name="MyArray[0].Selected" value="false" type="hidden" />

Indexes must start at 0 (at least with MVC 2) and must be consecutive. Your SomeClass will typically then have a property MyKey that would identify the checkbox and another property Selected which will give the state.

In my case, since I was only interested in checked items, it seems that I do not set the key for unselected items.

I do not have source code I uses here at home... The HTML fragment was found by "View source code" in Internet Explorer.

I think there might be an easier way to do it by having a list in the model and properly render a partial view with nested names.... but I haven't tried it yet.

i use this code when user click on button and work very good

[HttpPost]
        public ActionResult DocumentLabel(FormCollection model)
        {


            for (int i = 0; i < model.Count; i++)
            {
                AriaCRMEntities aria = new AriaCRMEntities();
                DocumentLabel label = new DocumentLabel();
                string lbl = model[i].ToString();
                string[] check = lbl.Split(',');

                bool chk = Convert.ToBoolean(check[0]);

                string name = model.Keys[i].ToString();
                string[] n = name.Split('_');
                string lblid = n[1];

                if (chk)
                {
                    label.LabelID_FK = Int32.Parse(lblid);
                    Guid id = Guid.NewGuid();
                    label.DocumentID_FK = id;

                    aria.DocumentLabels.AddObject(label);
                    aria.SaveChanges();
                }

            }


            return Content("0ok");
        }

but i want jquery post i need array check box whit select it to pass it to controller?

For jQuery, I do not understand well... Do you want that each time a check box is checked, a round trip is made to the server to post new values so that change are immediate?

If so, I think it would be best to have an action in your controller to just update the corresponding information on the server instead of posting all checkboxes.

If you still want to post the whole form then you might use something like

$(Your form selector here).submit();

and execute that code whenever a checkbox change. Assuming that you want to do it for all checkboxes on the web page, then it should not be hard to hook up the previous code to the appropriate event handler using jQuery.
