SavingContent event - update block content

SavingContent event - update block content - values not updated

Hi!

I am updating content on a block in the SavingContent event.

    [InitializableModule]
    [ModuleDependency(typeof(EPiServer.Web.InitializationModule))]
    public class BlockEventsInitialization : IInitializableModule
    {
        private IContentEvents _events;

        public void Initialize(InitializationEngine context)
        {
            _events = ServiceLocator.Current.GetInstance();

            _events.SavingContent += SavingContent;
        }

        private void SavingContent(object sender, ContentEventArgs e)
        {
            var block = e.Content as MyTestBlock;

            if (block != null)
            {
                block.Text = "New text";

                e.Content = block as IContent;
            }
        }

        public void Uninitialize(InitializationEngine context)
        {
            _events.SavingContent -= SavingContent;
        }
    }

In my case I am replacing blocks in a ContentArea, this is just a small example with the same result.

The Text property does not say "New text" until I reload the page, hitting "Ready to Publish", actually publish the block or go to another block/page and then go back the block I am updating.

I do not want to publish my changes, just save.

Anyone have an idea how to update values without reloading or publish the block?

This should do the trick for you:

Hi Magnus

You need to call CreateWritableClone and update the returned instance. By default all content is readonly for performance. I'm actually a little surprised an exception wasn't thrown. Something like this should do the trick:

var updateBlock = block.CreateWritableClone();
updateBlock.Text = "New Text";
e.Content = updateBlock as IContent;

Thanks for the response Aniket and David!

Setting e.Content with a CreateWritableClone() gives the same result, David.

Simplest possible scenario gives the same result:

        private void SavingContent(object sender, ContentEventArgs e)
        {
            e.Content.Name = "New name";
        }

The new value is not presented in the "All Properties" view until I do one of these:

A page refresh
Ready to Publish
Publish Changes
Navigate to another page/block and back

PS. Just to be clear; I am only referring to the "All Properties"-view and not "On-Page Editing"-view.

Best regards
Magnus

might be related to the case when value set on the client side is not the same that was mutated on the server. resulting in some weird dojo-mojo caching thingies?!

Did anyone find a solution to this? I'm attempting similar property changes on SavingConent and not having luck with the All Properties view refreshing afterwards

Valdis, I think weird dojo-mojo caching thingies is going to be the name of my next band. Lol!

Does anyone found and answer for this? Looking at similar problem.

I've been able to tell that that after save and event completing, server returns field with updated value. So seems like some events on UI are not taking that information into account.
