    Getting name of nearest ancestor of specific document type

    @CurrentPage.AncestorsOrSelf("Sektion").Last().Name

    Gets me the name of the nearest page of the Doc Type "Sektion".
    But if no ancestor exists of this doc type, i get an error.

    How do i check if an ancestor of the doc type "Sektion" actually exists?

    Hi Cluas,

    Maybe you could do something like this:

    if(CurrentPage.AncestorsOrSelf("Sektion")!= null){ 
        @CurrentPage.AncestorsOrSelf("Sektion").Last().Name
    }

    Hope this helps,

    /Dennis

    Hi,

    You need to check that the ancestor is not null before attempting to get any properties from it.

    So try something like:

    var sektion = @CurrentPage.AncestorsOrSelf("Sektion").Last();

    var sektionName = (sektion != null) ? sektion.Name : string.Empty;

    Cheers,

    Maff

    Using either of your suggestions i get:

     

    Sequence contains no elements

    Try using CurrentPage.AncestorsOrSelf("Sektion").Count() > 0 :-)
