Hi,

We face a strange StackOverflow exception on the load of the data to the XamTreeGrid. I've localized from all data the specific item which causing this problem. Unfortunately I am not able to progress further since rest of code is at Infragistics. So I would need a help to determine the problem root cause.

I've created a sample which reproducing this problem but it still contains a lot of company code so please open for this a private case so I can upload files.

My investigation: Making this child item as first level node fixes the problem. Changing a single documentation value from null to a value also fixing this problem. The value is not used directly in the tree node template so no NullReferences exceptions received only final one causing to crash the whole application.

The part of stack trace:
