How to get dropdownList selected Item from CSHTML page.

<div class="editor-field">
            @Html.DropDownList("ROUTE_GROUP_ID", String.Empty)
            @Html.ValidationMessageFor(model => model.ROUTE_GROUP_ID)
        </div>

Answer 1

If you want its value in jquery you can do like this

$('#ROUTE_GROUP_ID').val();

or if you want its value in controller you can access it from

Request.Form["ROUTE_GROUP_ID"]

or if your controller have a formcollection object then access the value like

formcollectionobj["ROUTE_GROUP_ID"]
