Getting a property from the nearest ancestor of document type
Im trying to do som recursivenes. I need to pull a value from a property from the nearest ancestor of two document types. Which ever is nearest...
@if (CurrentPage.HasValue("Kontaktpersoner")){
<p>CurrentPage has kontaktperson</p>
} else if (CurrentPage.AncestorsOrSelf("Sektion").First().HasValue("Kontaktpersoner")){
<p>Ancestor of doctype Sektion has kontaktperson</p>
} else if (CurrentPage.AncestorsOrSelf("Afdeling").First().HasValue("Kontaktpersoner"){ <p>Acncestor of doctype Afdeling has kontaktperson</p>
} else {
<p>No node has kontaktperson</p>
}
But this throws an error if both document types dont exist in the Ancestoror self scope.
@{ if (CurrentPage.HasValue("Kontaktpersoner", true)){ <p>CurrentPage has kontaktperson</p> } }
Then it will look recursively for the property value in ancestors. So if current page doesn´t have the property value then it will go up in the tree, until it found it.

How do i fix this?
Hi Claus,
If you do something like this:
@{if (CurrentPage.HasValue("Kontaktpersoner", true)){
<p>CurrentPage has kontaktperson</p>
}
}
Then it will look recursively for the property value in ancestors. So if current page doesn´t have the property value then it will go up in the tree, until it found it.
Hope this helps,

That was clean! and it works like a charm. I just cut my view in less than half.
Thanks a lot :)
