Hi all, I have a basic blog set up with paging and category/archive navigation. The paging currently works for All blog posts, but not for within categories. Can anyone advise me how I'd do this? My current code:

    @inherits Umbraco.Web.Mvc.UmbracoTemplatePage

@{
    var rootNode = Model.Content.AncestorOrSelf(1);
    var blog = rootNode.Children.First(x => x.DocumentTypeAlias == "blogMaster");
    var blogCategoriesFolder = blog.Children.First(x => x.DocumentTypeAlias == "blogCategoriesFolder");
    var blogPostsFolder = blog.Children.First(x => x.DocumentTypeAlias == "blogPostsFolder");
    var blogPosts = blogPostsFolder.Children().Where(x => x.IsDocumentType("blogPost")).OrderByDescending(x => x.CreateDate);

    // PAGINATION
    var pageSize = 3;
    var page = 1; int.TryParse(Request.QueryString["page"], out page);
    var totalPages = (int)Math.Ceiling((double)blogPosts.Count() / (double)pageSize);
    string pageURL = blog.Url + "?page=";
}

@if (blogPosts.Count() > 0)
{
    if (page > totalPages)
    {
        page = totalPages;
    }
    if (page < 1)
    {
        page = 1;
    }

    <div id="categories">
        @foreach (var blogPost in blogPosts.Skip((page - 1) * pageSize).Take(pageSize))
        {
            if (Request.Url.ToString().Contains("?category"))
            {
                var blogPostCategoryList = blogPost.GetPropertyValue<IEnumerable<IPublishedContent>>("postCategories");

                foreach (var blogCategory in blogPostCategoryList)
                {
                    string currentURL = Request.Url.ToString();
                    string blogCategoryURL = blogCategory.Id.ToString();

                    if (currentURL.Contains(blogCategoryURL))
                    {
                        <div class="item">
                            <a href="@blogPost.Url">@blogPost.Name</a>
                            <p>@blogPost.GetPropertyValue("postDate").ToString()</p>
                        </div>
                    }
                }
            }
            else
            {
                <div class="item">
                    <a href="@blogPost.Url">@blogPost.Name</a>
                    <p>@blogPost.GetPropertyValue("postDate").ToString()</p>
                </div>
            }
        }
    </div>

    if (totalPages > 1)
    {
        <nav aria-label="Page navigation example">
            <ul class="pagination">
                @if (page > 1)
                    {
                    <li class="page-item">
                        <a href="@pageURL@(page - 1)" class="page-link" aria-label="Previous">
                            <span aria-hidden="true">&laquo;</span>
                            <span class="sr-only">Previous</span>
                        </a>
                    </li>
                }

                @for (int p = 1; p < totalPages + 1; p++)
                    {
                        var active = (p == page) ? "active" : string.Empty;

                    <li class="page-item @(Html.Raw(active))">
                        <a href="@pageURL@p" class="page-link">@p</a>
                    </li>
                }

                @if (page < totalPages)
                    {
                    <li class="page-item">
                        <a href="@pageURL@(page + 1)" class="page-link" aria-label="Previous">
                            <span aria-hidden="true">&raquo;</span>
                            <span class="sr-only">Previous</span>
                        </a>
                    </li>
                }
            </ul>
        </nav>
    }

}
else
{
    <p>No posts found</p>
}

Thank you
