Hi

Does the TreeView in the web support Templates for the detail view?

Regards

Andrew

Very interesting... I have done something similar in some of my applications already.  Do all of the items in the tree have to correspond to a BO type?  Essentially what I do now in my application is place a ListView of the business objects in the NavBar.  Would I be able to set it up so that a root node would be the type of business object and then children nodes be the actual business objects (instead of a listview)?

I recently investigated how to get a TreeList in an ASP.NET XAF app and all the references seemed concerned with navigating views.

What I need is a way to navigate data.  For example, let say you have a client project task management app, so your top data nodes would be client companies, under each of which you'd have their projects, and under each project you'd have the tasks, and under each tasks you'd have time entries or something.  Clicking on a node should show say a ListView of that node's child data (clicking a project node would show a ListView of the project's tasks, for example) or a DetailView for the node (the project's details, for example).

Will this new feature do this hierarchical data navigation in addition to View navigation?

Looks great!  I'm looking forward to it.

Hi Oliver.

How is the syntax to use that?

regards

This is great. Looks great. Will be of immediate use. Thank you.

However PLEASE PLEAAAASE dont forget the basics and old promises. We really need recurrence in the Scheduler Module and integration of other common Devexpress components such as the RTF component.

Boris you can have reflexive data in a view ( see tv.devexpress.com/XAFtreelisthierarchies.movie ) but to show a fixed hierarchical relationship (Client-Project-Task) I suspect you would probably have to build a special purpose view.

Great ! Looking forward to this. An absolute must for complex applications with many BO's.

Andrew - you mean for the nodes? The term "detail view" has a certain meaning for XAF, so I'm a bit confused. In any case I don't know the answer right now, but perhaps somebody from the team does if you can clarify.

Steven - the general architecture of our "navigation items" hasn't changed, afaik, so you'll be able to integrate all sorts of things in the tree just like you always could with the navbar.

Boris - I think what you describe is what we already support for Windows Forms, but not yet for the web. This will be supported in 9.2, but it wasn't quite ready for screenshots yet.

Alain - the syntax? Where? It's a model thing - NavigationItems can now be arranged to create a hierarchy, which is then reflected in the navigation UI.

Luc - we never forget anything, we prioritize :-)

I know Oliver ... but that's is really sad to see that the Scheduler module was the first one out and yet still unfinished. Recurrence is such an important need, how can it not be prioritized more than that? Am not disapointed to have chosen XAF, but that particular point is a little bit sour.

"This will be supported in 9.2" - that's great news!  I'd love to see a DevExpress TV clip illustrating the feature once it comes out :-)

Thanks Oliver

I refer to use an attribute at class level to specify the arrangement, this can help to classes generator.

I am very happy to see useful new things in XAF! But the list is still long! My missing points:

- Search functionality

- Multi step (Wizard like) GUI

Very well! Why don't add a search textbox like Apple Spotlight? It's very usefull! I hope that all item of tree is checked by security system and the position can be defined as an attribute of the class!

yes,  as Steven Rasmussen said, i hope every treeNode can easily corresponded with an Business object.

  And all the treeData can be lazy-loaded...

Just a suggestion but you may want to put tags on this post (XAF, 2009.2, etc).

We're just about to release v2009.2 and it would be a good idea to have an "accumulator"

Are you going to supply the source for these examples with the release? I would like to see how you configured this.

This feature is so cool I was going to do something like that myself but then you guys turned out to do it for me.

Gary - yeah, source code of these samples is included.

I can't see ur source ?????
