Get every parent unless DokumentType != ProductGroup
Hello,

I'm really new to razor only changed some of the existing umbraco .cshtml files so far and encountered a problem when trying to build my own templates now.

I want to create a template for a "ProductGroup", each ProductGroup can have children of Type "ProductGroup" or "Product". In a live example it would maybe look like this:

expandable Items (ProductGroup) => Ink (ProductGroup) => someInkCartridges (Product) => Paper (ProductGroup) => somePaperTypes (Product)

I hope it's unterstandable.

What I know want is that when I'm on the Page for a Product, in the top example lets take the somePaperTypes-Page, I want a navigation to be displayed with the different Parent.Names and give the customer the option to klick on them as a anker-tag. So for our example it should look like this: expandable Items => Paper => SomePaperTypes Als three should be anker tags of course.

Here my code I've got so far, but it only works for .Children at the moment:
```
@{
    var groups = Model.Children;

    <ul>
    @foreach (var g in groups)
    {
        <li>
            <a href="@g.Url">@g.Name =></a>
        </li>
    }
        <li>
            <a href="@Model.Url">@Model.Name</a>
        </li>
    </ul>

}
```
How can I change the code know to achieve this with the parents until the parents DocumentType is not of type "ProductGroup" ||/or "Product"?

Best Regards,

Chris

I think I'm following what you need..

Try this (adjusting the .Level > 1 to be relevant to your node structure):
```
var parentNodes = Model.Content.Ancestors().OrderBy("Level");

foreach (var curAncestor in parentNodes)
{
    if (curAncestor.Level > 1)
    {
        <h2>@curAncestor.Name</h2>
    }
}
```

@Steve: .OrderBy("Level") Thats what I was looking for, it now works as intendet! Thanks.

edit: final code:

@{
    var productgroups = @Model.AncestorsOrSelf("ProductGroup").OrderBy("Level");

    <ul class="productgrouplist">
    @foreach (var pg in productgroups)
    {
            <li>
                <a href="@pg.Url">@pg.Name =></a>
            </li>
    }
        <li>
            <a href="@Model.Url">@Model.Name</a>
        </li>
    </ul>
}

What had me scratching my head was I was sure there was a method to get all Ancestors up to a certain level rather than from a level. There is the Up() traversing method which you can say .. Model.Content.Up(3) and go up 3 levels but this is no good for a traversa as it only returns the node at that particular levell!

I guess this might be a more succinct way of doing what you want too - also shows how to filter out document types.
```
var parentNodes = Model.Content.Ancestors().Where(x => x.DocumentTypeAlias != "ProductGroup" && x.Level > 1).OrderBy("Level");
```
Glad you've sorted it.
