Hello Telerik team,
With the below grid settings I select multiple cells of the grid keeping the Ctrl button pressed.
Now, on click of Ctrl + C, I get a System.NullReferenceException {"Object reference not set to an instance of an object."}
Please find the stack trace of the exception.
I donot get this exception on setting the selection unit to fullrow.
Please help with this matter.
Thanks,
Regards,
Mausami
