Add RadTreeNode to multiple RadTreeViews

[Xavier Hutchinson]

Hi,

I have some code that generates a tree of nodes and then adds them to a supplied RadTreeView, however it seems that the built Tree of RadTreeNode isnt able to be added to more than one RadTreeView.

I wanted to display it in multiple TreeViews without having to create a new Tree of RadTreeNode for each one as it can be taxing on my SQL server and client Processing.

Thanks,

Xavier.


(The TreeView registering / unregistering methods are at the bottom.)
Apologies for the messy code file... its been a rush job and I havent cleaned up yet ^^

Hi Xavier Hutchinson,

Thank you for writing. By design RadTreeNodes are removed from their parent collection if they are added to another parent collection, and hence the only way to achieve this is to create new nodes.

Adding a node to multiple tree views is not possible because the nodes consist of a visual and a logical part, with the logical part tightly coupled to the RadTreeView control. Doing so, if it was possible, will result in visual state corruption and other strange behavior.

You will probably have to do an iteration over your application design in order to address this case appropriately.

We are ready to assist you should you have other questions.

All the best,
Victor
