Hello Developer,
We have observed that after updation of Infragistic version 16.1.20161.1000 to 16.2.20162.1006 our tool occured crashing. Crashing is related with control XamDataTree.From our side we simple reinitilize list which contaion objects then we call OnPropertyChanged.Here i have attached details of crashing.So please give us feedback what is wrong.This issue is very critial for our customer.
With Best Regards
Nadeem

Hello Nadeem,
There was an issue with the XamDataTree in version 16.2.20162.1006 in which the XamDataTree was not handling initialization of its nodes correctly. This issue was found rather quickly in version 16.2 and has since been fixed.
In order to receive this fix, I would recommend downloading the most recent service release for version 2016.2 and installing it. To do so, you can follow the steps below:
1. View My Keys and Downloads: https://www.infragistics.com/my-account/keys-and-downloads2. Log in to the Infragistics web site if you are not already logged in.3. Select the product you would like to download a service release for (in this case 2016.2).4. Select the “Service Releases” tab.5. Select the download (e.g. Infragistics Xamarin.Forms 2015 - Service Release)
Please let me know if you have any other questions or concerns on this matter.
