I'm getting NullRefference exception. To reproduce run attached project, select left bottom cell, press enter. How can I avoid this exception?

Hi Dmitry,

Thanks for using Syncfusion products.

Please create the direct trac incident for the first exception (select left bottom cell, press enter)

I could not able to replicate the second exception(click on column header).
• Can you please give me some more details?

Please let me know if you need any more details.

Thanks
Ganesan
