Are they all the same document type? If so you can do something like this:

// Get root node:
var root = Model.AncestorOrSelf();

// Get all descendants, filter by type:
var nodes = root.Descendants("RecipeItem").Where("Visible");

Hi Amir, here is my code:

They are all the same document type.

I collect a querystring (the repository name). 'rep' is a set of items where their repository equals the query.

But I need to collect all items if the query is "All'

@using umbraco.MacroEngines
@inherits umbraco.MacroEngines.DynamicNodeContext 
@{
if (!string.IsNullOrEmpty(Request.QueryString["RepositoryName"])) {
string collect = String.Format("{0}", Request.QueryString["RepositoryName"]);
DynamicNode rep = null;
if (collect == "All") {
rep = COLLECT ALL ITEMS SOMEHOW!
} else {
rep = CurrentModel.DescendantsOrSelf().Items.SingleOrDefault(x => x.Name == collect);
}

I've tried your idea but I get error. 

Thanks in advance.

Hi James,

I was about to suggest what Amir posted, but if you are getting an error perhaps it is because you both have a mismatch in what "Model" represents... If not, could you please post the exact error message you're getting?

My theory is that James appears to be using v6+ MVC razor, where "Model" is something of type RenderModel, while Amir appears to be posting pre-MVC code where "Model" is of type DynamicNode.

(Oh, actually James I see you are using "CurrentPage" not Model, which I think is of type DynamicPublishedContent, but the problem still seems to be due to a mismatch in that first line of code.)

How about this instead to fix...?

if (collect == "All")
{
    //COLLECT ALL ITEMS SOMEHOW!
    rep = CurrentModel.AncestorOrSelf().Descendants("recipeItem").Where("Visible"); // where recipeItem is the doc type alias
}
else
....

Good luck!

is working on a reply...
