ContenArea modification does not work

Vote:

I m trying to modify content area programmaticly, but can not get it work. By hooking save event on episerver, I should be able to modify the content area on savingContent.

this simple logic is to delete content items on contentarea but does not save and refresh backend page.

 var page = e.Content as StandardPage;
            if (page.MyContentArea != null && page.MyContentArea.Items.Any())
            {
                var clone = page.CreateWritableClone() as StandardPage;
                foreach (var contenAreaItem in page.MyContentArea.Items)
                {
                    clone.MyContentArea.Items.Remove(contenAreaItem);
                }

                DataFactory.Instance.Save(clone, SaveAction.Save, AccessLevel.NoAccess);
            }

any help appreciated

Hi,

Maybe you need to assign contentArea to property

var page = e.Content as StandardPage;
if (page.MyContentArea != null && page.MyContentArea.Items.Any())
{
	var contentArea = page.MyContentArea;
    var clone = page.CreateWritableClone() as StandardPage;
    foreach (var contenAreaItem in contentArea.Items)
    {
        contentArea.Items.Remove(contenAreaItem);
    }
	
	// assign contentArea to property
	page.MyContentArea = contentArea; 

    DataFactory.Instance.Save(clone, SaveAction.Save, AccessLevel.NoAccess);
}

If you do SavingContent (before the actual save) you shouldn't need to save yourself.

If you do SavedContent (after saving has been done) you need to.

I wasn't aware that you need to re-assign CA to the property to get it populated. Weird

That is the most common way I've seen to trigger IsModified on the CA.

EPiServer doesn't care about the value if IsModified is false

I look at CA as observable collection and any modification should set IsDirty/IsModified/IWantToSave/Whatever flag to true, so EPiServer storage engine knows what to do. Thanks for tip.
