Using ContextMenu with TreeView

[Ben Hayat]

As of SL4, do we still need to set the plugin Windowless equals to True in order to use ContextMenu?
And is that requirement for using Context Menu for any UIElement?

Thanks!

Hi Ben,

With Silverlight 4 you don't need to use the Windowless parameter anymore. RadContextMenu opens on MouseRightButtonUp. If you want to change the event on which RadContextMenu opens, you can do that by modifying the EventName property.

Hey Kiro, good to see you. Thanks for confirmation.
I tried it without the Windowless and worked fine and kind of confirmed my thoughts that as of SL 4, this may not be needed but all the docs and blogs still point to having Windowless. And that's why I raised the question.

Perhaps some of the docs need update.
Thank you again.

Hi Ben,

Thanks for pointing out this inconsistency. I've logged this in PITS under the name "Documentation: Modify TreeView's ContextMenu help section so that it no longer uses Windowless" and we'll try to fix it as soon as possible.
Besides the help page, have you seen other places where we advocate the usage of Windowless? I've also updated your Telerik points accordingly.

Kind regards,

Hi Kiro;

Besides the help page, have you seen other places where we advocate the usage of Windowless?

Yes, here is also a blog post that says the same. You can see it right above the picture of browser in the blog.
http://blogs.telerik.com/valerihristov/posts/09-04-27/attaching_a_contextmenu_on_a_treeview_with_radcontrols_for_silverlight.aspx

In the online help, I saw several reference to it. There was the place of introduction, in the "How to" and somewhere else. And the repetition confused me more.

Kiro, I had posted another thread that if we could get a sample using WCF RIA services and QueryableDomainServiceCollectionView working with TreeView in Self-referencing mode.
I just want to see some guideline how to the the "Best Practice" using this new collection with TreeView in Self-referencing mode. Here is the post. It would be greatly appreciated, since the How To's don't cover the WCF Ria services and new collection.
http://www.telerik.com/community/forums/silverlight/treeview/radtreeview-usin-queryabledomainservicecollectionview.aspx

The points that I'm trying to put all together to make them work tegether:
a) Using WCF RIA Services
b) Using QueryableDomainServiceCollectionView
c) Using TreeView with above two
d) Including LoadOnDemand
e) Using "Prepared Item"
f) and etc.

As you can see, there are a lot of things that need to get cordinated.

Thanks again!

Hi Ben,

Thanks for pointing our these inconsistencies. We will fix the help pages and blog posts as soon as possible.

As for your request for an example "using WCF RIA services and QueryableDomainServiceCollectionViewSelf-referencing mode" working with TreeView in , I've added an item in our PITS under the name "TreeView: Integration example containing self-referencing hierarchy and QueryableDomainServiceCollectionView". This item will be available for tracking and voting tomorrow the latest.
Since our Q1 2011 release is right around the corner, I don't think that we will be able to prepare such an example before the official release, which is scheduled for the second half of March. However, once we release Q1 2011 we'll start working on the integration example.

Thanks Kiro for submitting my request. BTW, I never got those "Points" that you had mentioned in above post.

Looking forward to the new beta coming out.
Thanks!
