Hello J.T,
The TreeViewAdv can have upto 249 level childs. We could not reproduce any issue in the 43rd level. Also we have checked for 64th level without any issues, everything works fine. If you are still facing this problem please give us some sample which reproduces that issue so that it will be useful for us to help you.
Please let us know if you need further clarifications.

Hi J.T,

We have analyzed the scenario which you have mentioned. We tried with adding the child nodes upto 255 level and we dint get any exception. But after adding all when we try to open each child node we get exception in the 50th level. Sorry for the inconvenience caused.
This behavior is same as in Microsoft TreeView, we have tested with microsoft tree view and it stops in the 50th level itself. In our TreeViewAdv also it stops at 50th level after we handled that exception. This is the limitation in ItemsControl which we have inherited in TreeViewAdv actually. We have fixed that exception and the fixed assemblies will be available in our volume 2 release which is scheduled by the end of this month. If in case of any urgency please do create a support incident in Direct Track so that we can send you custom build assemblies.

Hi J.T,

We apologize for the inconvenience caused.

This was not incorporated in Vol2 release due to instability of the control and we would be fixing this issue in our Vol3 release.We will post the status of the issue once it has been incorporated.
