Hello fellow Umbraco'ers,

I'm working on www.roldskov.sp34k.dk as an online product catalogue. Right now I'm working on a sort of price filtering but I can't seem to figure out how to complete it.

If you look here you'll notice some price ranges on the left sidebar.

What functionality I'm trying to go for

What I wish to accomplish is to count how many products there is in a price range and if there is none, then it shouldn't be displayed.

Sidebare filtering is made like this

   <ul id="priceFilter" class="section sidebarList">
                <li @(String.IsNullOrEmpty(selectedpriceRange) ? currentClass : "")>
                    <a href="@CurrentPage.Url@queryStringBuilder("priceRange", "")">Alle priser</a>
                </li>
                @{  var priceRanges = new Dictionary<int, int>();
                    priceRanges.Add(0, 4999);
                    priceRanges.Add(5000, 9999);
                    priceRanges.Add(10000, 14999);
                    priceRanges.Add(15000, 24999);
                    priceRanges.Add(25000, 34999);
                    priceRanges.Add(35000, 44999);
                    priceRanges.Add(45000, 54999);
                    priceRanges.Add(55000, 95000);
                }
                @foreach (KeyValuePair<int, int> range in priceRanges)
                {
                    <li>
                        <a href="@CurrentPage.Url@queryStringBuilder("priceRange", string.Format("{0}-{1}", range.Key, range.Value))">
                            @string.Format("{0} - {1}", range.Key, range.Value)
                        </a>
                    </li>
                }
            </ul>

Products are being written out like this:

    <div id="categoryCollection">
                    @if (!string.IsNullOrEmpty(selectedpriceRange) && selectedpriceRange.Contains("-"))
                    {
                        string[] priceArray = selectedpriceRange.Split('-');
                        int minPrice = 0;
                        int maxPrice = 0;
                        if (priceArray.Count() == 2 && int.TryParse(priceArray[0], out minPrice) && int.TryParse(priceArray[1], out maxPrice))
                        {
                            selectedItems.AddRange(productTypes
                                .Where(x => x.HasValue("price") &&
                                x.GetPropertyValue<int>("price") > minPrice &&
                                x.GetPropertyValue<int>("price") < maxPrice)
                                .Skip((page - 1) * pageSize).Take(pageSize));

                            foreach (var item in selectedItems.Skip((page - 1) * pageSize).Take(pageSize))
                            {
                                @buildItemProduct(item);
                            }
                        }
                    }
                    else
                    {
                        foreach (IPublishedContent item in productTypes.Skip((page - 1) * pageSize).Take(pageSize))
                        {

                            @buildItemProduct(item)
                        }

                    }
                </div>
