Hi Jaya,
I'll see if I can create a small app that repro's the problem but I suspect it's somewhere in my code.
The treeView's SelectedNode property always throws a 'null reference' exception when the treeView is disposed and then instantiated a second time.
>Hi Mark,
Thank you for using Syncfusion products.
I am afraid that I could not able to reproduce this issue at my end.
Could you please send me the Customized TreeViewAdv class file and details to reproduce the issue. This will help us to analyze the issue further.
Please have a look at the below sample and let me know if I missed anything.
