Hi Carlos

If I understand your question correctly you should be able to use Distinct like Tom does in this post perhaps? http://our.umbraco.org/forum/developers/razor/27295-Find-and-count-unique-values-in-a-dynamicNodeList-

Jan, I actually found what I was looking for. I found another post 
http://our.umbraco.org/forum/developers/razor/19020-Is-there-something-like-'GroupBy'?p=0#comment120345 

And took it apart.  This is what I did using a part of their example. I think I was missing a step somewhere. Thanks for getting back to me.  If you have a simpler way or if you see antying that is not necessary in the code, please let me know.  

string creatorList = "";

<ul>
      @foreach(dynamic node in @Model.NodeById(1089).Descendants("ScienceResearchUpdatesPost").OrderBy("CreatorName"))
      {
        if (creatorList != node.CreatorName)
        {
          <li>@node.CreatorName</li>    
        }
        creatorList = node.CreatorName;
      }
      </ul>  

Jan,

One more question. Now that I have the CreatorName list.  I was wondering how I would build a Querystring to show the nodes only shown by a selected name.

I am using the base pagination Macro and currently have all items of the certain NodeTypeAlias listing.  I now have all of the CreatorNames 

How would I filter these once a name is selected?

I tried to make a simple query string but I don't know what to do with it after I have made it.  Any help is appreciated.

This is my build query string

var baseNode = @Model.AncestorOrSelf("DWTBlogLanding");
  <h3>@Dictionary.DWTAuthors</h3>
      string creatorList = "";
  <ul>
      @foreach(dynamic node in @Model.NodeById(1089).Descendants("ScienceResearchUpdatesPost").OrderBy("CreatorName"))
      {
        if (creatorList != node.CreatorName)
        {
          <li><a href="@[email protected]">@node.CreatorName</a></li>    
        }
        creatorList = node.CreatorName;
      }

     </ul>

Here is my base page that lists the posts of that NodeTypeAlias.

  var pagesToList = @Model.NodeById(1089).Descendants("ScienceResearchUpdatesPost").OrderBy("CreateDate desc");

  // configuration
  var itemsPerPage = String.IsNullOrEmpty(Parameter.ItemsPerPage) ? 3 : int.Parse(Parameter.ItemsPerPage);
  var previousLabel = String.IsNullOrEmpty(Parameter.PreviousLabel) ? "Previous" : Parameter.PreviousLabel;
  var nextLabel = String.IsNullOrEmpty(Parameter.NextLabel) ? "Next" : Parameter.NextLabel;

  // paging calculations
  var numberOfItems = pagesToList.Count();
  int currentPage = 1;
  if (!int.TryParse(HttpContext.Current.Request.QueryString["Page"], out currentPage)) {
    currentPage = 1;
  }
  currentPage--;
  var numberOfPages = numberOfItems % itemsPerPage == 0 ? Math.Ceiling((decimal)(numberOfItems / itemsPerPage)) : Math.Ceiling((decimal)(numberOfItems / itemsPerPage))+1; 

  <p>
    Total Items: @numberOfItems <br />
    Items per Page: @itemsPerPage<br />
    Pages: @numberOfPages;<br />
    Current Page: @(currentPage)
  </p>

 var baseNode = @Model.AncestorOrSelf("DWTBlogLanding");
  
  
  <ul class="dwtPostList">
    @foreach(var item in pagesToList.Skip(currentPage*itemsPerPage).Take(itemsPerPage))
    {

     <li>

    }
    
    var Pages = Enumerable.Range(1, (int)numberOfPages);
    foreach(var number in Pages) {
      if (number-1 != currentPage) {
      <a href="?page=@number">@number</a>
      } else {
      <span class="dwtPagingCurrent">@number</span>
      }

    }

    if (currentPage < Pages.Count()-1) {
      <a href="?page=@(currentPage+2)">@nextLabel &raquo;</a>
    } else {
      <span class="pagingDisabled">@nextLabel &raquo;</span>
    }
  }

  </div> 

is working on a reply...
