We usually advise against disabling the row virtualization in RadGridView, especially if you're planning on using the control with a big amount of data.
That said, I'm not sure I understand your scenario completely, but RadGridView exposes the option to apply different data templates on cells using a CellTemplateSelector without interference with the virtualization. In case this is something that might fulfill your requirements, please go through the respective article here
If you still decide to disable the recycling, you can achieve it by setting the EnableRowVirtualization property
I hope this is helpful.
