Templates, (partial) views and macros

Umbraco 7

Hi,

I have the following code to list children of document type "carsList" in a partial view macro, and it works as just expected.

@inherits Umbraco.Web.Macros.PartialViewMacroPage

@{
    var numberOfVehicles = Model.MacroParameters["numberOfVehicles"].ToString() != null ? Model.MacroParameters["numberOfVehicles"].ToString() : "4";
    int numberOfVehiclesInt = numberOfVehicles.AsInt();
    var vehicles = Model.Content.AncestorOrSelf(1).Descendants("carsList").FirstOrDefault().Children;
}

@if (vehicles.Where(x => x.IsVisible()).Any())
{
    foreach (var vehicle in vehicles.RandomOrder().Take(numberOfVehiclesInt))
    {
        <h2>@vehicle.Name</h2>
    }
}

However, I would like to add vehicles to this list from a document type called "motorcyclesList". I tried by changing to following

var vehicles = Model.Content.AncestorOrSelf(1).Descendants().Where(x => x.DocumentTypeAlias == "carsList" || x.DocumentTypeAlias == "motorcyclesList").FirstOrDefault().Children;

but this still only list the cars.

Any suggestions?

Hi Marcus

Try to remove FirstOrDefault from your code:
```
var vehicles = Model.Content.AncestorOrSelf(1).Descendants().Where(x => x.DocumentTypeAlias == "carsList" || x.DocumentTypeAlias == "motorcyclesList").Children;
```

Hi Alex,

I tried remove FirstOrDefault but then I cant get the children (got the error message "Cannot assign method group to an implicitly-typed variable").

Any ideas :)

Hi Marcus

Idea:

var vehiclesFolders = Model.Content.AncestorOrSelf(1).Descendants().Where(x => x.DocumentTypeAlias == "carsList" || x.DocumentTypeAlias == "motorcyclesList");

    var vehicles = new List<IPublishedContent>();

    foreach (var vehiclesFolder in vehiclesFolders)
    {
        vehicles.AddRange(vehiclesFolder.Children);
    }
