Question

I have a Telerik MVC Grid where there is a column Names , Gender , Age . I am going to use a ListBox which is bound to Gender ( coming from SQL 2k8 Table” Person”. I am using Entity Framework, POCO classes , Repository Pattern ). Then there is a Image button as ” Search ” .

When a user selects few values from ListBox and then hits the ” Search” Button Telerik MVC Grid which is on the same page ( I am rendering a User control which has actual Telerik MVC Grid) should be populated .

how to do this ? how to pass the selected ListBox values back to controller Action ” SearchPerson” . There is a way of doing this using JQuery . But i dont know how to do this . Please help me

                    return PartialView("SearchVoucherNum", ervm);
                }


            }
            else
            {
                ERAViewModel eras = this.WorkerService.SearchByPIN(era.Eras.PIN);
                return PartialView("SearchVoucherNum", eras);
            }
        }
        catch (Exception ex)
        {
            bool reThrow = ExceptionPolicyWrapper.HandleException(ex, ExceptionPolicies.MVCPolicy);
            if (reThrow)
                throw;
        }
        return null;
    }

The best way to do this is to use jQuery.

You need your listBox and to bind your grid in AJAX.

Here’s some sample code I have in an application :

View

<div class="content-box-filter">
        <label>Filter:</label>
        <%= Html.DropDownList("Years", Model.Years) %>
    </div>
    <div class="content-box">
        <div class="content-box-header">
            <h3>News</h3></div>
        <div class="content-box-content">
            <%= Html.Telerik().Grid<News>()
                    .Name("Grid")
                    .Columns(colums =>
                     {
                         colums.Bound(c => c.Title).Title("Titre").ClientTemplate("<a href=\"" + Url.Action(MVC.News.Modifier()) + "/<#=IdValue#>\" ><#=Title#></a>");
                         colums.Bound(c => c.Title).Title("Inscriptions").ClientTemplate("<a href=\"" + Url.Action(MVC.News.Inscriptions()) + "/<#=IdValue#>\" >fichier excel</a>");
                         colums.Bound(c => c.Published).Title("Publiée").HeaderHtmlAttributes(new { @class = "center-text" }).HtmlAttributes(new { @class = "center-text" }).ClientTemplate("<img src=\"../Content/images/icons/<#=Published#>.png\" alt=\"<#=Published#>\" />");
                         colums.Bound(c => c.CreationDate).Title("Date").HeaderHtmlAttributes(new { @class = "center-text" }).HtmlAttributes(new { @class = "center-text" }).Format("{0:MM/dd/yyyy}");
                         colums.Bound(c => c.IdValue).Title(" ").HeaderHtmlAttributes(new { @class = "center-text" }).HtmlAttributes(new { @class = "center-text" }).ClientTemplate("<a href=\"" + Url.Action(MVC.News.Modifier()) + "/<#=IdValue#>\" title=\"Modifier\" ><img src=\"../Content/images/icons/pencil.png\" alt=\"Modifier\" /></a>");
                         colums.Bound(c => c.IdValue).Title(" ").HeaderHtmlAttributes(new { @class = "center-text" }).HtmlAttributes(new { @class = "center-text" }).Format("<a id=\"deleteLink{0}\" href=\"#\" title=\"Supprimer\" onclick=\"if(confirm('Voulez-vous vraiment supprimer cette nouvelle?')){ return deleteNews('{0}');} else { return false;};\"><img src=\"../Content/images/icons/cross.png\" alt=\"Supprimer\" /></a>");
                     })
                    .DataBinding(d => d.Ajax().Select("ListAjax", "News", new { year = DateTime.Now.Year }))
                    .Sortable()
            %>
            <%= Html.AntiForgeryToken() %>
        </div>
    </div>
    <script type="text/javascript">
        var token = $('[name=__RequestVerificationToken]').val();
        $(document).ready(function() {
            $('#Years').val(<%=DateTime.Now.Year%>);
            $('#Years').change(function() {
                var grid = $('#Grid').data('tGrid');
                grid.rebind({ year: this.value });
            });
        });
        function deleteNews(newsId) {
            $.post('DeleteNews', { __RequestVerificationToken: token, id: newsId }, function(data) {
                if (data == 'true') {
                    $('#deleteLink' + newsId).parent().parent().remove();
                } 
                return false;
            });
            return false;
        };
    </script>

The NewsController action :

[GridAction]
        public virtual ActionResult ListAjax(int year)
        {
            var gridModel = new GridModel<News>();
            gridModel.Data = _newsRepo.GetByYear(year);
            return View(gridModel);
        }

Let me know if you still have question.
