Hi,
What is the property CanBeSelectedInAddRange in UltraTreeNode about?
An exception that I am investigating in our program (null reference in Infragistics.Win.UltraWinTree.UltraTreeNode.get_UIElement()) seems to be related to it.
This crash happens when setting UltraTreeNode.Selected = true. If the property CanBeSelectedInAddRange is true when calling that code, it becomes false and the exception is thrown. This is the only connection between the crash and the state of the program that I was able to do.
This only happens with Infragistics 9.2 (previously we had 7.3) and I'm investigating to see if this bug is caused by our app. or by Infragistics. If you have any reason to believe this is an Infragistics bug I could try provide a stack and maybe fill a bug.
Thank you,
Alex
You were right, this seems to be indeed Infragistics problem and it has been fixed (in the April maintenance release, I think). It has a bug number TFS24418, and I wasn't even aware that we had license for the source code.
If it wasn;t happening in a previous version and it is now, then by definition it is our bug. If you can provide a simple sample or steps to reproduce, we can take a look and see what's going on.
