I want to delete block with broken links from my page. Fx we use EPi Server Commerce, and sometime a product is deleted from the PIM in Commerce and I need to remove all the Blocks that had that product referred.
But something is 'wonky'...
Some blocks sometimes still exists after I've tried to delete them. If I put a new block in the ContentArea, it seems to remove the old values and the ContentArea is fine again. It's like EPi server does not see my change as a change and doesnt publish anything.
private void CleanNonExistingBlocks(PageData page)
{
page = page.CreateWritableClone();
var type = page.GetType();
var props = type.GetProperties();
bool isPageDirty = false;
foreach (var propertyInfo in props)
{
if (propertyInfo.PropertyType != typeof(ContentArea))
continue;
ContentArea value = propertyInfo.GetValue(page, null) as ContentArea;
if (value == null)
continue;
List<ContentAreaItem> list = value.Items.ToList();
bool isListDirty = false;
foreach (var contentAreaItem in list.ToList())
{
IContent found;
if (_contentRepository.TryGet<IContent>(contentAreaItem.ContentLink, out found))
continue;
isPageDirty = true;
isListDirty = true;
list.RemoveAll(c => c.Equals(contentAreaItem));
}
if (isListDirty)
{
value.Items.Clear();
foreach (ContentAreaItem contentAreaItem in list)
value.Items.Add(contentAreaItem);
propertyInfo.SetValue(page, value);
}
}
if (isPageDirty)
{
_contentRepository.Save(page, SaveAction.Publish, AccessLevel.NoAccess);
_outputMessages.Add(page.Name + " - ");
}
}
The problem is you are using .NET Reflection API:s and not EPiServers API. See this questions accepted answer for an example of how to work with ContentArea in code:
