Thank you for writing.
Currently, the export and print mechanisms of RadGridView do not export the RightToLeft layout of the grid. This is because they work with the data layer of RadGridView and they do not know how the data is actually represented in the UI. We have plans on improving the export and printing support, but currently they are not scheduled and I cannot give you a specific time frame. We will have your feedback in mind when we make our plans for the implementation.
I hope this will be useful. Should you have further questions, I would be glad to help.
All the best,
the Telerik team
