Add block to ContentArea programmatically C# Episerver 11.x


Hi Team,

I was trying to add the blocks to the ContentArea programmatically and used the following code.

DisplayOption threw an exception of type 'System.NotImplementedException'

//Save the page

contentRepository.Save(myPage, EPiServer.DataAccess.SaveAction.Publish,EPiServer.Security.AccessLevel.Read);

//Save the Block

ContentAssetHelper contentAssetFolder = ServiceLocator.Current.GetInstance<ContentAssetHelper>();
var contentAsset = contentAssetFolder.GetOrCreateAssetFolder(myPage.ContentLink);

var newBlock = contentRepository.GetDefault<RawHTML>(parentLink: contentAsset.ContentLink);

var writableClonePage = (InnerPage)myPage.CreateWritableClone();

var rep = ServiceLocator.Current.GetInstance<IContentRepository>();

newBlock.HTMLContent = new XhtmlString(WebUtility.HtmlDecode(c.Content));

IContent icontentBlock = (IContent)newBlock;
icontentBlock.Name = c.PaneName;

ContentReference savedReference = rep.Save(icontentBlock, SaveAction.Publish, AccessLevel.NoAccess);

//Add the Block to ContentArea

var AddblockItem = new ContentAreaItem
ContentGuid = Guid.NewGuid(),
ContentLink = savedReference

rep.Save((IContent)writableClonePage, SaveAction.Publish, AccessLevel.Read);

Can you please help me where I made a mistake?

Hi Praful,

I am getting error((DisplayOption threw an exception of type 'System.NotImplementedException')) on this below line.




It looks like your Content Area is null?

Could you add the following line:

writableClonePage.ContentArea = new ContentArea();

Also, where did you get this code sample from? You shouldn't set:

ContentGuid = Guid.NewGuid()

Hi, most probably the solution is what Jake suggested you in his comments. I did the same mistake to not initialize the content area type property. Before adding items into that, you can check if the content area is null then initialize it, otherwise you can just add items.

Please let us know if that not fixes your issue.
