I have a page type that store some options, and I want to use them in a property (SelectOne) of a block type. When create a block, that property will get options from parent page (get in SelectionFactory). I tried to get current page by IPageRouteHelper but always return the HomePage

        public IEnumerable<ISelectItem> GetSelections(ExtendedMetadata metadata)
        {
            var currentContent = metadata.FindOwnerContent();
            var currentPage = currentContent;
            if (currentContent is BlockData)
            {
                currentPage = _pageRouteHelper.Service.Page;
            }
            return GetColorOptions(currentPage);
        }

Thanks for your help.

Hi Ten Ten,

Quite simply we don't have this context in the selection factory, you're editing a block which has no direct relationship to a page. Is there a way you can rethink what you're trying to achieve?

The only "sort of" work-around I can this of is if you can ensure that the blocks are always created "For this page", then you could retrieve the page like this:

public IEnumerable<ISelectItem> GetSelections(ExtendedMetadata metadata)
{
    var content = metadata.FindOwnerContent();

    ContentAssetFolder assetFolder;

    if (!_contentLoader.Service.TryGet(content.ParentLink, out assetFolder))
    {
        // Return defaults here
        return new ISelectItem[0];
    }

    PageData page;

    if (!_contentLoader.Service.TryGet(assetFolder.ContentOwnerID, out page))
    {
        // Return defaults here
        return new ISelectItem[0];
    }

    return GetColorOptions(currentPage);
}

This feels kind of brittle though, so depends how important the integrity of the color selection is.
