Ok, I found something really cool today!

I have multiple checkboxes that the user can select, and I was struggling to retrieve the selected values in my controller.

Luckily, mvc offers some great assistence; check out this code:

<% using (Html.BeginForm("ShowData", "Home")) {  %>
  <% foreach (var o in ViewData.Model) { %>
    <input type="checkbox" name="selectedObjects" value="<%=o.Id%>">
    <%= o.Name %>
  <%}%>
  <input type="submit" value="Submit" />
<%}%>

and all the selected items are available in a typed array!

public ActionResult ShowData(Guid[] selectedObjects) {
    foreach (Guid guid in selectedObjects) {
       

    }
}

so, the trick is to use the same name for the controls, and the posted values are automagically put in an array.

Nice :)
