    to list the nodes divided per year i use this query but i havenm't the results

    Hi. The "GroupBy" method could be helpful:

    @{
     var yearGroups =  Model.Children.GroupBy("DisplayDate.Year");
     foreach(var yearGroup in yearGroups) {
            <h2>@ yearGroup.Key</h2>
            foreach(var node in  yearGroup) {
                <p>@node.Name</p>
            }
        }
    }

    Hi. I have got the name "displayDate" from your own query. Your code lets to guess that it's supposed to be some custom property of your document type. Isn't that?

    The "Year" is just a property of the System.DateTime .NET type, so .GroupBy("DisplayDate.Year") should group the list of nodes by the year part of "DisplayDate".

    This is my entire script:

    @inherits umbraco.MacroEngines.DynamicNodeContext
    @{
        int pageSize; // How many items per page
        int page; // The page we are viewing

        /* Set up parameters */
        
        if (!int.TryParse(Parameter.PageSize, out pageSize))
        {
            pageSize = 6;
        }

        if (!int.TryParse(Request.QueryString["page"], out page))
        {
            page = 1;
        }

        /* This is your basic query to select the nodes you want */

        var nodes = Model.Descendants.Where("catCount > 2").OrderBy("displayDate desc");
        
        int totalNodes = nodes.Count();
        int totalPages = (int)Math.Ceiling((double)totalNodes / (double)pageSize);
        
        /* Bounds checking */
        
        if (page > totalPages)
        {
            page = totalPages;  
        }
        else if (page < 1)
        {
            page = 1;
        }
    }

    <h2>Found @totalNodes results. Showing Page @page of @totalPages</h2>

    <ul>
        @foreach (var item in nodes.Skip((page - 1) * pageSize).Take(pageSize))
        {
            <li><a href="@item.Url">@item.TitoloNews</a> (@item.DisplayDate.ToShortDateString())</li>
        }
    </ul>

    <ul class="paging">
        @for (int p = 1; p < totalPages + 1; p++)
        {
            string selected = (p == page) ? "selected" : String.Empty;
            <li class="@selected"><a href="?page=@p" title="Go to page @p of results">@p</a></li>
        }
    </ul>

     

    The content tree is:

    Homepage-

       Notizie (DT folder)
         Year (DT Folder)
            Node (DT page)

     

    when i start this script i have 0 results
    This is my problem!

     

    Thanks for your patience

    gabriele
