Hi Ron,

Never done that, check if the even gets hit when you open a user tree, if that event gets hit, you can use custom actions in the tree.

Cheers,

Richard

Hi Ron,

Yeah you should be able to do this with the following code:

    public class YourTreeEvent : ApplicationBase
    {
        public YourTreeEvent() {
            umbraco.cms.presentation.Trees.BaseTree.BeforeNodeRender += new umbraco.cms.presentation.Trees.BaseTree.BeforeNodeRenderEventHandler(BaseTree_BeforeNodeRender);        
        }

        void BaseTree_BeforeNodeRender(ref umbraco.cms.presentation.Trees.XmlTree sender, ref umbraco.cms.presentation.Trees.XmlTreeNode node, EventArgs e)
        {
            if (node.NodeType == "users" &&  node.Menu != null)
            {
                node.Menu.Insert(0, new YourActionHere());
                node.Menu.Insert(1, umbraco.BusinessLogic.Actions.ContextMenuSeperator.Instance);
            }
        }
    }

YourAction will be inserted as the first action in the context menu within the users-Tree.

NodeType would/could be "users", "userPermissions" or "userTypes" depending on where you want your action to appear. These are the TreeAlias(es) for the users-app (the Users-section).

Thanks @Richard and @Morten

I already tried that and the event only gets hit in the content section.
Any suggestions?

Ron

File a bug report at codeplex, the event really should fire on all trees, right?

@Morton

Have you used that code before or did you assume it would work?

Ron

@Ron

I assumed it worked as I have used in it in the content and media sections. I never used it with:

node.NodeType == "users"

but assumed it worked, since it has worked for me with:

node.NodeType == "media"

I can do a quick test for the users-section and post my result.
Otherwise I quess you would have to override the loadUsers-class, which is the class that loads the tree and adds actions.

- Morten

@Morton

The weard thing is that the loadUsers class inherits from BaseTree, so you would think it has to work.
Thanks for the quick test, then I'm sure its not just me :)

Ron

Yeah, your right. It doesn't hit the Event in the Users section.

But I think I would out why! If you look in the loadMedia and BaseContent classes, you'll find this piece of code in public override void Render(ref XmlTree Tree):

base.OnBeforeNodeRender(ref Tree, ref node, EventArgs.Empty);
if (node != null)
{
  Tree.Add(node);
}
base.OnAfterNodeRender(ref Tree, ref node, EventArgs.Empty);

So the events are only fired before and after the node has been added to the Tree.

So if you want it to work right now you have to override the loadUsers class or create a new tree loader for the users section.

{
  Tree.Add(node);
}
base.OnAfterNodeRender(ref Tree, ref node, EventArgs.Empty);

So the events are only fired before and after the node has been added to the Tree.

Damnit! Sorry about the triple posting :-S The post wasn't updating after hitting submit.

- Morten

But how can I make Umbraco use my new loadUsers after I override the event?
(Sorry I don't have much experience in that area.)

Ron

Yes it makes sence.

Don't like it tho. It's a shame that I need to change the core in order to get it working.
However it seems to be the only way to go.

Thanks a lot!

Ron

I agree, and maybe we should ask some of the core developers if there is any particular reason why the Users-section tree isn't firing the event.
...Or simply add it as an issue on Codeplex.

- Morten

HI Ron,

Great that it worked for you. There is a package Action that helps you update the apptree values when you need to create a package out of this. Check out http://packageactioncontrib.codeplex.com/ and http://www.prolificnotion.co.uk/update-application-tree-package-action-for-umbraco

Cheers,

Richard

Thanks Richard,

I choose not to change the tree. I just added an additional one.
That way I don't need to change Umbraco.

Ron

is working on a reply...
