User Changed Themes At Runtime

My entire site is set to the bootstrap theme, is it possible to set something up that allows the user to select what theme they want to use while using the site through a dropdown list that contains premade themes made available through the standard set that is offered from Syncfusion for most of its components including the grid.

<Dropdown>      @Html.EJ().DropDownList("DropDownList1").Datasource((IEnumerable<object>)ViewData["LocalDataSource"]).DropDownListFields(Df => Df.Text("Text")).ClientSideEvents(e=>e.Change("change"))      <GRID>   @(Html.EJ().Grid<object>("FlatGrid")           .Datasource((IEnumerable<object>)ViewBag.datasource)                             .AllowPaging()    /*Paging Enabled*/                 .SelectionType(SelectionType.Single)            .AllowResizing()                          .AllowFiltering()                                              .Columns(col =>           {             . . .                       }))   </div>      <Change Event>   <script>        function change(args) {                     var link = window.document.getElementsByTagName('link'); //get the link of css file           var value = args.value; // get the dropdown value           $(link).attr('rel='nofollow' href', "/Content/ej/web/" + value + "/ej.web.all.min.css") // Change the theme       }   </script>

Works great thanks for the help!
