Bind MVC Grid with dropdown

[Dennis]

I have a dropdown and an mvc grid. When the Submit button is clicked it called a method passing in the value from the dropdown and populates a grid. The problem is when the sort or paging is clicked I cannot figure how to pass the value from the dropdown. The example shows no parameters being passed in the the grid filtering the results with a startswith (I don't want to do).

@using (Html.BeginForm("Filtering", "Home"))

{

    <p>

        <label for="startsWith">

            <strong>Contact Name</strong> starts with:</label>

        @Html.DropDownList("Classifications", ViewData["ClassificationItems"] as SelectList, new { style = "width:100px;" })

        <button class="t-button t-state-default" type="submit">

        Apply</button>

    </p>

     

     

}

@(Html.Telerik().Grid(Model)

        .Name("Home")

        .Columns(columns =>

        {

            columns.Bound(o => o.CodeID).Width(120);

            columns.Bound(o => o.Title).Width(200);

            columns.Bound(o => o.Status);

        })

                    .DataBinding(dataBinding => dataBinding.Ajax().Select("_Filtering", "Home")

            .Sortable(sorting => sorting

            .SortMode(GridSortMode.SingleColumn)

            .AllowUnsort(true)

            .OrderBy(order =>

                {

                    order.Add(o => o.CodeID);

                })

             )

             .Pageable()

 

        )

Controller:

public ActionResult Filtering(string classifications = "")
        {
            ViewData["ClassificationItems"] = new SelectList(Classifications.List, "ClassificationText", "ClassificationText", classifications);
            ViewData["SelectedCategory"] = classifications ?? "Type";

            var codModels = new List<CodeModel>();
            var model = _codeRepository.Search(classifications).ToModel();
            return View(model);
        }


        [GridAction]
        public ActionResult _Filtering(string selectedCategory = "")
        {
            return View(new GridModel<CodeModel>
            {
                Data = _codeRepository.Search(selectedCategory).ToModel()
            });
        }
