We currently use the Syncfusion v126.96.36.199. We created the TreeViewAdv which contains a node with a depth around 20. It causes the problem "Unhandled exception" and I checked the call stack, the final function is "Syncfusion.Shared.Base.dll!Syncfusion.Drawing.DrawingUtils.NCPaintHelper ... Unknown". Please see the attached file for more details.
Please let me know the solution for this case.
If you have any question, please do not hesitate to let me know.
Thank you very much!
