I am playing with events in Umbraco 7 but I have an event which seems not to be triggered.
What I am intending to do is cancel the deletion of content node called "Home".
But while debugging, it seems that ContentService_Deleting method isn't hit at all.
I tried ContentService.Saving (in another test) and that is wokring perfectly. So i thought that Deleting would work somewhat the same.
I wonder what I am doing wrong. Any help would be appreciated.
This is what I have:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Web;
using Umbraco.Core;
using Umbraco.Core.Events;
using Umbraco.Core.Models;
using Umbraco.Core.Publishing;
using Umbraco.Core.Services;
namespace CustomEvents
{
public class CustomEvents : ApplicationEventHandler
{
public CustomEvents()
{
ContentService.Deleting += ContentService_Deleting;
}
void ContentService_Deleting(IContentService sender, DeleteEventArgs<IContent> e)
{
foreach (var node in e.DeletedEntities)
{
if (node.Name == "Home")
{
e.Cancel = true;
}
}
}
Yes good point! I was thinking in the wrong direction. What I needed was ContentService.Trashing...overlooked that one.
Do you happen to know how I can force some kind of refresh after the trashing is cancelled? Because the node is visually deleted but it's still there after a refresh in the backend. That the node is still in place is a good thing of course that was my intention but a refresh somehow would be perfect.
Thanks a lot for pointing me in the right direction!
Sorry I don't think that is possible. The events aren't linked to the UI. You can show a cancel message in the speech bubble, but that's it probably. Please mark a post as the solution if it helped you.
Thanks Jeroen. I will try those examples. I just had my reservation because those post were many years old. But if it still applies I think that's fine.
Those examples don't work in Umbraco 7.2 - trying to cast the current handler as a page errors. I'm still trying to figure out how to (1) show a speech bubble inside of an event and (2) cancel the page / tree change, or refresh the entire page because removing a node from the tree when the node was not actually removed is misleading.
ContentService Deleting Event not firing

This is what I have:
Hello,
Did you try deleting it by emptying the recycle bin? Otherwise it might not be triggered because it's only being moved to the recycle bin.

Thanks for your quick reply! Is there somewhere documentation about the speech bubble?
Here are some links:
