    copied!<p>I have the following view that has tow dropdowns and one button:</p> <pre><code>@model RoomReservation.Webb.Models.HomeViewModel @{ ViewBag.Title = ""; Layout = "~/Views/Shared/_Layout.cshtml"; } &lt;h2&gt;Index&lt;/h2&gt; &lt;fieldset&gt; &lt;legend&gt;Select a city and a hotel&lt;/legend&gt; &lt;br /&gt; &lt;br /&gt; &lt;br /&gt; @Html.DropDownListFor(x=&gt;x.City_DDL_ID, new SelectList(Model.AllCities, "Value", "Text"),"...pick a city..." ) &lt;br /&gt; &lt;br /&gt; @Html.DropDownListFor(x =&gt; x.Hotel_DDL_ID, Enumerable.Empty&lt;SelectListItem&gt;(), "...pick a hotel...", new { disabled = "disabled"}) &lt;br /&gt; &lt;br /&gt; &lt;input id="SearchButton" type="submit" onclick="window.location.href='/Home/SearchForRooms'" disabled="disabled"/&gt; &lt;/fieldset&gt; &lt;script type="text/javascript" language="javascript"&gt; $('#City_DDL_ID').change(function () { var selectedCity = $(this).val(); if (selectedCity != null &amp;&amp; selectedCity != '-1') { $.getJSON('@Url.Action("GetHotels")', { id: selectedCity }, function (hotels) { var hotelsSelect = $('#Hotel_DDL_ID'); hotelsSelect.empty(); $.each(hotels, function (index, hotel) { hotelsSelect.append($('&lt;option/&gt;', { value: hotel.Value, text: hotel.Text })); }); $('#Hotel_DDL_ID').attr('disabled', false); $('#SearchButton').attr('disabled', false); }); } }); &lt;/script&gt; &lt;script type="text/javascript" language="javascript"&gt; function onsubmitclcik() { var SecondDrpId = $('#Hotel_DDL_ID').val(); window.location.href = '/Home/SearchForRooms?parameter=' + SecondDrpId; </code></pre> <p>} </p> <p>I would like to get a value from second dropdown so that I can give it as paramater to my method f**ired from the button atribute "onclick". It is now working (above script). But my action still gets null parameter. Here is the code:</p> <pre><code>public ActionResult SearchForRooms(int SecondDrpId) { if (SecondDrpId &gt; -1) return View(); //Here goes some model, not important else return RedirectToRoute("Home/Index"); } </code></pre> <p>Here is the Chrome parameter: Request URL:http://localhost:22191/Home/SearchForRooms?parameter=3 Request Method:GET thank you**</p>
