MVC 4 dynamic partial views and posted models RRS feed

  • Question

  • Hi,

    We are building an MVC 4 site with razor.  We have a view on the site that has a dropdown.  When one of the values is selected in this dropdown, some simple jquery calls a controller action which dynamically returns some data has a partial view.

        function change() {
            var value = $("#DataSourceId").val();

            if (value == 0 || isNaN(value))
                // clear the div
            else {
                $('#Data').load("@Url.Action("GetDatasourceData" , "Profiles" )", { id: value }, null);


    This data is used to populate a checkbox list with n values, so that a user can select one or more items they require.  It returns them like this:
                var model = new DatasourceData
                        ProfiledDataSourceList = pdsList,
                        AvailableSchemaList = pdscList

                return PartialView("Partials/_Data", model);

    These items are used to build a list of checkboxes one of more of which could be selected by a user.  

            @Html.CheckBoxListFor(x => Model.Items,
                                    x => x.AvailableSchemaList,
                                    x => x.Value,
                                    x => x.Name,
                                    x => x.SelectedSchemaList,

    The partial view is wrapped in a form submit block.  The aim is that when a user submits the form, their selections are captured by an action that has been decorated with a HttpPost attribute.

        @using (Html.BeginForm())   



    <input type="submit" id="submit" name="submit" value="Create"/>    



    We have a controller action that starts like so:


    public ActionResult Create(ProfileModel model)

    We would expect to have the selected items returns as part of the model parameter to the Create action.  What we find however is that no items are populated in our expected lists. When we inspect the post via Firebug, we find that checkboxes list selections do not appear to be submitted back to the action. I don't know if this is a problem with checkboxes selection or if it's because we're dynamically building the view/partial views at runtime, so when a post happens - the model can only be populated with objects that we on the page when it was loaded (rather that any dynamically created content).

     Is there a better way of doing this?
