    Getting Nodes By Level & DocType

    I am trying to create a simple navigation but seem to be struggling... This is not working when I thought it should?  Any tips appreciated.

    @inherits umbraco.MacroEngines.DynamicNodeContext
@{     
    var level = String.IsNullOrEmpty(Parameter.Level) ? 1 : int.Parse(Parameter.Level);
    var bCategories = @Model.AncestorOrSelf(level);

    if (bCategories != null) {
        <ul id="mainnavigation">
            @foreach (var cat in bCategories.Children("nodeTypeAlias == \"BusinessCategory\"").Where("Visible").OrderBy("SortOrder")) 
            {
                <li><a href="@cat.Url">@cat.Name</a></li>
            }
        </ul>
    }
}

    I keep getting the error

    Cannot invoke a non-delegate type

    Seems its where I call the DocType that is causing an issue, if I remove

    ("nodeTypeAlias == \"BusinessCategory\"")

    It works, but defeats te object as I need to filter by both level AND DcoType

    Got it working in the end

    @inherits umbraco.MacroEngines.DynamicNodeContext
@{     
    var level = String.IsNullOrEmpty(Parameter.Level) ? 1 : int.Parse(Parameter.Level);
    var bCategories = @Model.AncestorOrSelf(level);

    if (bCategories != null) {
        <ul id="mainnavigation">
            @foreach (var cat in bCategories.Children.Where("nodeTypeAlias == \"BusinessCategory\"").Where("Visible").OrderBy("SortOrder")) 
            {
                <li><a href="@cat.Url">@cat.Name</a></li>
            }
        </ul>
    }
}

    It's populating dynamicnodelists on nodetypealias - so this should actually also work (and I think orderby should be the default sort order, ?):

    @foreach (var cat in bCategories.BusinessCategory.Where("Visible"))

    What if there are multiple nodeTypeAliases to check for?  Would Lee's solution be the correct way to do it then?

    Thanks,

    You just saved my ass with:

    Where("nodeTypeAlias == \"BusinessCategory\"")

    I really needed to find a way in razor to stop all my DateFolders showing in nagivation.

    Thanks

    Paul
