Infragistics control XamDataTreeNode IsExpanded regiter to PropertyChanged

Question

I'm using Infragistics control called XamDataTree. XamDataTree holds a collection of XamDataTreeNode. After inserting all XamDataTreeNode items to XamDataTree. I am doing for-each on the collection and changing the IsExpanded property of each one of the nodes. As a result of that, Infragitics code behind register node.PropertyChanged. This registration cause to memory leak because there is no unregistered operation.

Does any one knows why unregistered doesn't being called ?

thanks

If you have a memory leak due to the control you should contact Infragistics support with an example so they can address the issue.

If the memory leak is only specific to your application then you should post code that you are using as part of your question so others can see what is being done.
