Thanks for the reply.
So, this feature, which worked in version 2013 and which been supported, doesn't work any more ?
Indeed, it's work with disabling navigateable, but i need it. And it was working before I update the version.
Can you give me what is the utility to use your grid in virtual if we can't select, navigate, create, update, delete, add large datas ? Just read data ?
I'm very tired to work with your product. All interesting features disappears in each update. And all your answers are : "Not supported", "Not a bug because we don't know how to fix it", "Write a workaround".
What is the vision for your grid ? Increase and improve features or it will be deprecate in future ?
I need to know where you want to go and check if we are still in an agreement.
