Infragistics2.WebUI.UltraWebNavigator

We have old Infragistics2.WebUI.UltraWebNavigator.v7.1 in use.  It is erroring out during Tree expanding/scrolling with 

1119.3333740234375 is not a valid value for Int32.

What is the last version of UltraWebNavigator?  I don't see the same namespace in 2021 version.  I would like to try the last version of the control if possible, then try any replacement in newer namespace if it was replaced.  Thanks.

Hello,

Since the classic controls were retired after v11.1, I recommend you upgrading to it, in order to see if the issue still exist in it. Please keep in mind that v11.1 is out of the support scope so it will not receive any bug fixes.

If the issue still exists in v11.1 I would recommend you upgrading to the newest version, however this process would take some effort since the new controls have new/changed functionalities and properties, so changes in the code are necessary. Below you can find a forum thread where I have provided further details on the migration from the classic controls to their new equivalents:

Please let me know if you have any questions.
